Custom Optifine Entity Model not working?? | Blockbench | Page 1

subtle basin Apr 21, 2025, 5:27 PM

#

Anyone know how to make Custom Boat model texture packs with optifine? I'm using block bench.

I have exported the file as a JEM file. I created a pathway for entity, named the JEM model after the ID of the acacia boat resource pack, then created a seperate pathway into textures, with the texture of the model. Yet when I go into the game, the boat is the default version. The custom resource pack folder IS a proper resource pack folder as well. It has the pack meta, etc. So it works fine, just don't know why my boat textures and model aren't loading in? Maybe I have the name wrong??

I used CEM template, followed instructions properly, exported as JEM, exported texture file, made sure it was under the "Optifine entity" section.

I just don't know what I'm doign wrong

subtle basin Anyone know how to make Custom Boat model texture packs with optifine? I'm using...

This might be a stupid question but
do you have Optifine or EMF/ETF installed?
those are required for you to see a custom boat model

fierce wren This might be a stupid question but do you have Optifine or EMF/ETF installed? t...

I do not have them installed

#

But there are resource packs that have custom boat models that only require optifime

#

And they work fine without the EMF and ETF mods

fierce wren Apr 22, 2025, 1:03 PM

#

subtle basin But there are resource packs that have custom boat models that only require opti...

yes you need either only Optifine or both EMF and ETF
not all 3

#

ok so your boat model just doesn't show up at all?

subtle basin Apr 22, 2025, 1:05 PM

#

fierce wren ok so your boat model just doesn't show up at all?

no

#

it doesn't show up like AT ALL

fierce wren Apr 22, 2025, 1:05 PM

#

is your boat just boat.jem or is it a specific variant like oak_boat.jem

subtle basin Apr 22, 2025, 1:05 PM

#

its a specific variant

#

specifically the Raft with chest.jem

#

I also tried using boat.jem but nothing happened either

fierce wren Apr 22, 2025, 1:06 PM

#

ok interesting it saves it as chest_raft.jem

#

I'm not 100% sure if that's the correct name

#

I'm gonna boot up my game and test

subtle basin Apr 22, 2025, 1:07 PM

#

alr alr, i'll give it a try

#

just to double check, the file path should be resource pack > assets > minecraft > optifine > cem > chest_raft.jem

#

and then after minecraft, i need to put the texture of that into textures > entity and it should also be named chest_raft

fierce wren Apr 22, 2025, 1:09 PM

#

subtle basin just to double check, the file path should be resource pack > assets > minecraft...

yep that's all correct

subtle basin Apr 22, 2025, 1:10 PM

#

hmm, yeah that's what i got

fierce wren Apr 22, 2025, 1:12 PM

#

ok interesting so I'm using EMF and ETF which should functionally be the same as Optifine
and using chest_raft.jem does work

#

could you show your model in Blockbench with the whole screen?

subtle basin Apr 22, 2025, 1:13 PM

#

yeah sure

#

#

don't mind the texture names on the left. I changed them to "chest_raft" in the textures file path in my resource pack

fierce wren Apr 22, 2025, 1:15 PM

#

ah ok so yea there is an issue with this
have you seen the tutorial on the CEM template loader?

subtle basin Apr 22, 2025, 1:15 PM

#

I have

fierce wren Apr 22, 2025, 1:15 PM

#

all elements must be inside the root bones that were created as part of the template

subtle basin Apr 22, 2025, 1:15 PM

#

oh?

#

what does that mean

fierce wren Apr 22, 2025, 1:15 PM

#

are all those cubes inside the original folders?

#

these

subtle basin Apr 22, 2025, 1:16 PM

#

Oh

fierce wren Apr 22, 2025, 1:16 PM

#

cus otherwise they will not show up in the game

subtle basin Apr 22, 2025, 1:16 PM

#

I see

#

so

#

just to clarify

#

the only thing that matters is the blocks in the right file

#

size, etc does not matter

fierce wren Apr 22, 2025, 1:16 PM

#

basically

#

there is no size limit to entity models

#

that I know of

#

so yea recreate those 6 folders and name them exactly

subtle basin Apr 22, 2025, 1:17 PM

#

Can I chuck all the blocks into one file, or do I actually have to sort it properly

fierce wren Apr 22, 2025, 1:17 PM

#

you can put them all in one

#

and leave the others empty

#

just make sure they are all present

subtle basin Apr 22, 2025, 1:17 PM

#

ok, let me do it, give me like 3 mins and i'll get back to you whether it works or not

fierce wren Apr 22, 2025, 1:18 PM

#

alright 👍
I would recommend putting them all in the "bottom" folder so they don't have weird animations to deal with

subtle basin Apr 22, 2025, 1:21 PM

#

LMAOO

#

i mean

#

it definetely did something

#

subtle basin Apr 22, 2025, 1:22 PM

#

fierce wren alright 👍 I would recommend putting them all in the "bottom" folder so they do...

not sure what's happening here

fierce wren Apr 22, 2025, 1:25 PM

#

ohh
ok so in entity models, you can't rotate cubes, but you can rotate folders
so for every rotated cubes/group of cubes with the same angle, they must go in a folder

#

that might be a challenge since you have 430 cubes

subtle basin Apr 22, 2025, 1:26 PM

#

oh hellllll nah

#

so

#

how do i do that

#

because i can't create new folders

#

i only have 6 folders to work with

fierce wren Apr 22, 2025, 1:26 PM

#

not new root folders

#

but inside those folders you can do whatever you want

subtle basin Apr 22, 2025, 1:27 PM

#

oh

#

I see what you mean

#

so

#

should i reset all the rotated cubes to normal 90 degrees

#

THEN put them into a new folder

#

and then rotate them

fierce wren Apr 22, 2025, 1:27 PM

#

you can do I think ctrl shift g when you select cubes

fierce wren Apr 22, 2025, 1:27 PM

#

subtle basin should i reset all the rotated cubes to normal 90 degrees

probably yeah

#

I would save a copy first

#

so you can see what everything should be angled like

#

so yea not sure why Blockbench let you rotate individual cubes...

#

it should have some sort of warning message

subtle basin Apr 22, 2025, 1:29 PM

#

alright

#

i think im just going to create a new model

#

very similar

fierce wren Apr 22, 2025, 1:29 PM

#

that might be faster ngl

subtle basin Apr 22, 2025, 1:29 PM

#

because I can't be asked moving all those cubes lmao

#

430 cubes is crazy

#

although i don't actually have too many rotated cubes

fierce wren Apr 22, 2025, 1:29 PM

#

also one thing to note, the more faces you have on your model, the more laggy it is

subtle basin Apr 22, 2025, 1:30 PM

#

although, i DO have some rotated cubes inside the actual car itself

#

if i leave them in, will it still be bugged?

fierce wren Apr 22, 2025, 1:30 PM

#

I think yea their rotations will just be set to 0

#

one more thing, looks like your texture isn't working

subtle basin Apr 22, 2025, 1:31 PM

#

really? how so

fierce wren Apr 22, 2025, 1:31 PM

#

it's all purple and black

#

which means the game can't load it

subtle basin Apr 22, 2025, 1:31 PM

#

wait are you talking about the in game ss or in blocbench

#

ahh

fierce wren Apr 22, 2025, 1:31 PM

#

in the game

#

is your texture named "bamboo.png" in assets/minecraft/textures/entity/chest_boat?

subtle basin Apr 22, 2025, 1:32 PM

#

ohhh wait

#

i don't have that file path

#

i just put it straight into the entity folder

fierce wren Apr 22, 2025, 1:33 PM

#

ah ok
also, could you show the first few lines of your jem file in a text editor?

#

it should have info on the texture the model is using

subtle basin Apr 22, 2025, 1:35 PM

#

sure

#

subtle basin Apr 22, 2025, 1:36 PM

#

fierce wren it should have info on the texture the model is using

here u go

fierce wren Apr 22, 2025, 1:37 PM

#

ok you can remove the entire line that starts with "texture"

#

that's making it use a texture in the item folder which I don't think works

#

if you remove that line then it defaults to using the vanilla texture
which is the one in entity/chest_boat

#

well the one in the vanilla file location, which you are also replacing with this pack

subtle basin Apr 22, 2025, 2:32 PM

#

wait @fierce wren

#

what if instead of recreating a model, if i just put EVERY single rotated cube into a folder, and put that folder into the "bottom" folder

#

would that fix it maybe?

fierce wren Apr 22, 2025, 2:35 PM

#

well each set of cubes with a different angle needs its own folder

#

so not exactly

subtle basin Apr 22, 2025, 3:06 PM

#

just fixed it actually, im getting small progress but it's going really really well

#

slight issue with the positioning however

#

#

in block bench it looks normal

#

but in game (i haven't adjusted the texture yet, i jsut wanted to make sure the model was at least working first), its a bit weird

#

#

It's like rotated and positioned really weirdly @fierce wren

subtle basin Apr 22, 2025, 3:36 PM

#

ok @fierce wren

#

got the model done, the positioning is still weird

#

but i tried to apply the texture, but it comes back with this

#

subtle basin Apr 22, 2025, 3:54 PM

#

yeah not sure why the texture isn't working. I renamed the texture in the blockbench as chest_raft (same as what the CEM template texture is called).

I also changed the name of the texture in the entity folder multiple times to bamboo, chest_raft, etc. I even tried to put them into the folder like you said with entity > chest_boat

Afterwards, i deleted the entire texture line like you said as well.

The texture is still black

fierce wren Apr 22, 2025, 3:54 PM

#

ok I'm back lemme read all this

subtle basin Apr 22, 2025, 3:54 PM

#

and for some reason everytime I change the texture (even though it doesn't load), the position of the baot changes too

#

all good

fierce wren Apr 22, 2025, 3:55 PM

#

ok so it looks like the "bottom" folder has these rotations by default so you should try to replicate that

#

so 0, -90, -90

#

also when you save your model in Blockbench it probably re-added the texture line to the file

#

which you should remove so it uses the texture in entity/chest_boat

subtle basin Apr 22, 2025, 3:56 PM

#

fierce wren also when you save your model in Blockbench it probably re-added the texture lin...

i made sure that everytime i updated the model, i removed the line

fierce wren Apr 22, 2025, 3:57 PM

subtle basin Apr 22, 2025, 4:00 PM

#

wait

#

i'll double check the file

#

so delete the entire texture line

#

then in the chest_boat file

#

what should the texture name be called?

#

@fierce wren shouuld it be named chest_raft

#

also does this code look right:

#

ahh

#

there we go

#

the texture worked now

#

but the rotation is still off

subtle basin Apr 22, 2025, 4:03 PM

i also tried editing it like this, but this is what happens when i change it:

#

fierce wren Apr 22, 2025, 4:25 PM

#

ok so you can probably put everything inside a subfolder in bottom, and rotate it to counteract the bottom's rotation

subtle basin Apr 22, 2025, 4:25 PM

#

just tried that

#

doesn't seem to work

#

@fierce wren

#

this is what happens as soon as i move it

#

nvm smh it's a download

#

uhh

#

1 sec

#

Moving by arrows is fine

#

But this is what happens as soon as I try touching the actual element position

#

@fierce wren

fierce wren Apr 22, 2025, 4:31 PM

#

yeaaa the angled cubes move weirdly

subtle basin Apr 22, 2025, 4:33 PM

#

again, like i tried to just move the stuff around even tho it wont sit right with the player and looks weirdi n block bench

#

but if i moe the boat down

#

then refresh the pack

#

then the boat in game moves like north east or sum

#

instead of just down

#

like idk wtf to do

fierce wren Apr 22, 2025, 4:34 PM

#

Maybe I can take a look at the model
when you have things in rotated folders then translation gets weird

if you could that would literally be a life saver

#

📎 chest_raft_1111.bbmodel

#

Here's the model. Let me know if you do decide to take a look at it and see if you can figure out the problem with positioning it right. Because I'm literally so stuck

fierce wren Apr 22, 2025, 4:40 PM

#

ah ok I see what might be going on
you're trying to move the position of the "bottom" bone, but that will just be undone in the game to always be the default values
so trying to move the model by moving the root bone will just result in it moving in a weird way in a different direction

#

the bottom bone should stay at position -15 -1 -4

#

also you've sent a bbmodel, not a jem model

#

so it doesn't behave the same way when you edit it

#

in jem models, the position of the group is independant of the position of the cubes inside it

#

but when I try to change the group position in the bbmodel it also messes with the cube positions

subtle basin Apr 22, 2025, 4:46 PM

#

ah okay I see

#

in that case what should I do?

#

also here's the Jem file

#

📎 chest_raft.jem

#

@fierce wren

#

let me know what I can do to fix it, or even if you wanted to try to fix it 😭 I do appreciate all the help you've given so far though, massive help

fierce wren Apr 22, 2025, 4:51 PM

#

ok I'm working on it to see what actually works

#

why are all of these cube's positions like 0.0005 pixels off 😭

#

do you have a version before you messed with all the rotation stuff

#

maybe the position values are cleaner

subtle basin Apr 22, 2025, 4:55 PM

#

fierce wren why are all of these cube's positions like 0.0005 pixels off 😭

ik 😭

#

Im pretty sure like

#

wait

#

actually

#

no i don't

#

wait

#

maybe i do

fierce wren Apr 22, 2025, 4:55 PM

#

🙏

#

One of the annoying things about these models with few limitations is that it's easy to make it just slightly off

subtle basin Apr 22, 2025, 4:57 PM

#

im pretty sure the main reason why it's so off

#

are the rotated cubes

#

im trying to fix it up rq

#

i might have to get back to you on this tomorrow

#

because i need to fix a lot of the cubes

#

how many pixels do you need for it to work properly? @fierce wren

#

say if I had something like 16.625

#

does that work

fierce wren Apr 22, 2025, 5:02 PM

#

subtle basin how many pixels do you need for it to work properly? <@963438192600707102>

wdym...?

#

oh I just want to be able to center the model

#

and the whole thing being 0.0005 pixels off makes that almost impossible

#

so as long as the model is symmetrical around some nice number it should be fine

subtle basin Apr 22, 2025, 5:03 PM

#

okay

#

so like the number 16.625 is fine

#

its like relatively clean

subtle basin Apr 22, 2025, 5:04 PM

#

fierce wren so as long as the model is symmetrical around some nice number it should be fine

not like 16.2502197598 something

fierce wren Apr 22, 2025, 5:04 PM

#

yea

#

exactly

#

preferably it would be mostly whole numbers

#

but ofc you have to use decimals sometimes for details

subtle basin Apr 22, 2025, 5:11 PM

#

yeah I'll have to get back to you tomorrow

#

it seems that basically ALL the cubes are weird

#

gonna have to edit 430 cubes lmaoo

subtle basin Apr 22, 2025, 5:13 PM

#

fierce wren but ofc you have to use decimals sometimes for details

It’s a decently detailed car

#

So there will be quite a few decimals. The top is 2 decimal places

#

Maybe SOME have 3 but not much

fierce wren Apr 22, 2025, 5:14 PM

#

yeah that's fine
as long as it can be centered around a nice point

subtle basin Apr 22, 2025, 5:14 PM

#

fierce wren yeah that's fine as long as it can be centered around a nice point

So with it tryna be centred

#

I don’t understand because like

#

I tried to move it around, but it was shifting the rotated blocks

fierce wren Apr 22, 2025, 5:14 PM

#

what model format are you creating the model in

subtle basin Apr 22, 2025, 5:15 PM

#

I’m creating it in optifine entity

fierce wren Apr 22, 2025, 5:15 PM

#

ok so that's good

#

if you just create it using the template it should be easier

subtle basin Apr 22, 2025, 5:16 PM

#

fierce wren ok so that's good

What’s the point of trying to centre it because won’t the rotated blocks just move

subtle basin Apr 22, 2025, 5:16 PM

#

fierce wren if you just create it using the template it should be easier

I could but I’d have to completely remake the model again

#

And that would be a bit uhh

fierce wren Apr 22, 2025, 5:16 PM

#

yea true...

subtle basin Apr 22, 2025, 5:16 PM

#

Annoying hahaha

subtle basin Apr 23, 2025, 2:27 PM

hey @fierce wren what is the id or jem model thingo for a acacia boat with chest

fierce wren Apr 23, 2025, 2:30 PM

#

idk, probably just acacia_chest_boat

subtle basin Apr 23, 2025, 2:46 PM

#

I tried that, doesn't seem to work

#

works fine with chest_raft @fierce wren but nothing else works

#

even tried oak and all that other stuff

fierce wren Apr 23, 2025, 2:47 PM

what Minecraft version are you on

subtle basin Apr 23, 2025, 2:47 PM

1.20.1

fierce wren Apr 23, 2025, 2:48 PM

#

oh then I think you can't have a separate jem model for the different types of boats
that was added in 1.21.4

#

you will need to use the random entities features

#

with .properties files and all that

which I have little experience in

fierce wren oh it's about spawning piglins without armor?

no I was making a custom mob but I used my previous mob as the base, and now whenever I try to load my old mob in blockbench it loads the new mob

@fierce wren

#

thank you for all the help man

#

finally got it to work hahahaa

#

I also found out what the issue was

#

As I thought, the placement of the blocks shouldn't matter. Even if it was like 5.0000893 on the position or something. It shouldn't affect the entire model completely.

Turns out my issue was making the model, but then what I did was instead of loading the CEM template, I instead just made the model, then like you said, created my OWN folders called "bottom" and all that other stuff.

Instead, what I should've done was load the CEM template model, copy and paste MY model into it, but it all into Bottom (it'll shift the positioning around). Then adjust the position, and then once I like it, I delete all the original boat models and textures, replacing it with my own texture.

Then in the end result I get this:
