Hello,

For the past few years we have multiple pets and our own custom texturepack with allot of custom stuff.
Somehow, recently our otter pet, the free one from nocsy is behaving weird.
We have MEG 4. and updated the otter with the newest files from mcmodels. Mythicmobs and mcpets replaced.

But still somehow, we have a purple texture, but as soon as I walk into the purple texture, I see the otter just fine. So what can be the issue here?

Also, when a player teleport back to their "lands" claim, their pets turns into a drowned zombie?

When I do /meg summon nocsy_otter_v2 I spawns perfectly fine with no issues.

#

Server: paper-1.21.8-50.jar
Mythicmobs: MythicMobsPremium-5.11.1.jar
Modelengine: ModelEngine-4.0.9.jar
Mcpets: MCPets 4.1.6

#

Left mcpets, right /mm mobs spawn nocsyotter.
Middle meg summon

halcyon arch Hello, For the past few years we have multiple pets and our own custom texturep...

Hi 👋 For the texture thing, it's gonna be impossible for us to troubleshoot it because this is not related to MCPets (but rather ModelEngine, custom stuff that you have that might be premium and can not be shared, or ItemsAdder/Oraxen interferences).

For the drowned issue though, it might be because either:

The otter must be on Despawn: true in the MythicMobs mob config (see MythicMobs/Packs/Nocsy/nocsy_otter.yml I believe)
For some server setups, the model mechanic must be on sync=true, see #1384994220984762408 message

nova zephyr Hi 👋 For the texture thing, it's gonna be impossible for us to troubleshoot it ...

Thanks for your reply.

There is nothing wronng with mythic mobs and modelegine. If I spawn the pet through modelegine, there is no issue.

Chatgpt says it is the NMS layer mcpets provides that breaks it?:

What MCPets actually does (important)

When MCPets spawns a pet, it does NOT just spawn the MythicMob.

Internally, MCPets:

Spawns the MythicMob

Wraps it with a PetController (NMS layer)

Injects:

custom follow logic

interaction detection

distance checks

teleport handling

Overrides the entity renderer

With ModelEngine 4, this override causes Minecraft to:

➡️ Render the entity bounding volume using a fallback render
➡️ Which becomes a missing-texture cube

That cube:

is not an entity

is not a particle

is not configurable

cannot be /killed

disappears when you are inside it

only exists when MCPets is controlling the entity

This is why:

Spawn method Result
/meg summon ✅ perfect
MythicMobs spawn ✅ perfect
MCPets spawn ❌ purple cube

halcyon arch Thanks for your reply. There is nothing wronng with mythic mobs and modelegine....

Well, chatgpt certainly has not read the code. There is no nms involved in MCPets. If you don't trust me on what I suspect to be the issue (and I'm certain of it), I won't be helpful to you 😶

#

Although it's weird that spawning through modelengine only does not yield any troubles, I'm certain it does not come from MCPets

I trust you haha. Im just getting pointed back and forth

nova zephyr Dec 23, 2025, 9:25 PM

#

Model display only goes through Modelengine, there's no other display options except if you're using something like ItemsAdder or Nexo above your pack

halcyon arch Dec 23, 2025, 9:25 PM

#

Also have a ticket at mythic for the mythic/meg.

#

I dont use nexo, nor itemsadder, nor oraxen

#

Just plain flat texturepack with mythic mobs, modelegine and mcpets.

nova zephyr Dec 23, 2025, 9:26 PM

#

halcyon arch I dont use nexo, nor itemsadder, nor oraxen

Then if it's only this and that you have nothing else installed, I suggest you to look at your Minecraft launcher logs to see what textures are not loaded properly

halcyon arch Dec 23, 2025, 9:26 PM

#

The pet always worked, untill we updated to meg 4

nova zephyr Dec 23, 2025, 9:26 PM

#

But if there's any kind of possible issue it comes from MEG or additional resources you have installed for sure since you don't have any resource pack manager

halcyon arch Dec 23, 2025, 9:27 PM

#

No client errors for the texturepack, that is the whole issue, I normally troubleshoot trough client logs

nova zephyr Dec 23, 2025, 9:27 PM

#

halcyon arch Left mcpets, right /mm mobs spawn nocsyotter. Middle meg summon

It appears the apparent issue would be the MythicMobs layer then trusting that screenshot

#

Have you tried updating MythicMobs?

halcyon arch Dec 23, 2025, 9:27 PM

#

yeah watch the video I posted

#

in the first post

#

if you walk "through" the box, then it shows the normal pet xd

nova zephyr Dec 23, 2025, 9:28 PM

#

I could be an issue with a dev build as well, would need retrograding then

halcyon arch Dec 23, 2025, 9:28 PM

#

nova zephyr Have you tried updating MythicMobs?

I am at the max versionm for 1.21.8

#

and latest modelegine and latest mcpets.

nova zephyr Dec 23, 2025, 9:29 PM

#

halcyon arch if you walk "through" the box, then it shows the normal pet xd

Hitbox display issue maybe?

#

There's nothing MCPets handles through all this sadly 😕

#

MCPets does not have any impact on model display, it only spawns the pet through MythicMobs and cling a pet-like AI to it

halcyon arch Dec 23, 2025, 9:30 PM

#

Yeah. I hoped to "update" your pet files through mcmodels would fix it, sinced our old files where for meg 3. but it didn't help

#

Oke

#

Well thank you for taking the time to respond to me.

#

Lets hope somebody at mythic knows the answer:)

nova zephyr Dec 23, 2025, 9:31 PM

#

halcyon arch Yeah. I hoped to "update" your pet files through mcmodels would fix it, sinced ...

If it's not updated then it should work fine (no reports from customer prior to this, I could be wrong)
