[tough hound]

Well, I'm seeing what looks like UV overlap

and skewed lightmap UVs in general

[carmine imp]

what meaning is

is only like that when i using baked

thanks, i will try it

btw do you know why when i baked there no shadow?

if i using realtime or mixed, the shadow is show up

i am sorry if my english is broken, english is not my first language

i still learning

[tough hound]

Baked-only light source shadows are limited by lightmap resolution, which has to be relatively low
Realtime shadows are much sharper, but more expensive

Mixed lights are calculated as realtime for direct shadow and light, but also cause bounce lighting when baking
So they're an expensive combination of both realtime and baked

[carmine imp]

in lighting i using baked indirect and the lightmap resolution is 10. i try to make it 50 but nothing happend?

[tough hound]

You'll have to bake again after increasing the resolution

[carmine imp]

I've tried it but it seems there is no change

[tough hound]

And let it finish
It says "total bake time 0:00:00" which might imply that the bake was canceled, so we could be looking at unfinished results currently

With 50 resolution and a laptop GPU the bake will likely take at least multiple minutes

[carmine imp]

but when i bake, it only like 1 minutes?

[tough hound]

It could be faster than I expected, but we usually want visual confirmation in the bake time counter that it really did finish with no concerning errors or warnings appearing in the console

[carmine imp]

this is 50 lightmap resolution

there still no shadow

and this is mixed 10 lighmap resolution and have shadows

[tough hound]

It seems to say that the bake took 1 second which makes no sense to me
There's some information in the console that's being cut off

In addition to warnings about more UV overlap

notice this

[carmine imp]

so the problem is in baked have 01

[tough hound]

You should show the whole console window with all the warnings

[tough hound]

I see
You really need to take care of all the UV overlaps

[carmine imp]

ok bro

[tough hound]

You can use the visualization mode as instructed by the warning

[carmine imp]

i will learning this first

before asking again

[tough hound]

The notice about punctual light shadows isn't dangerous or very important, just means that realtime shadow resolution was reduced

[tough hound]

Good luck! There's quite a lot to study with baked lightmapping

[carmine imp]

so only the yellow and red is problem right?

[carmine imp]

thanks

[tough hound]

It depends
I think warnings about the GPU stopping the bake for whatever reason are/used to be grey/white, even if they were important

as an example

but in this specific case yes

[carmine imp]

can i fix it with blender? because all the asset i make in blender

i planning to reduce the faces

[tough hound]

The easiest thing to do is to check "generate lightmap UVs" on the import settings of every mesh

But also in Blender you need to check that the meshes don't have unapplied scale transforms

[carmine imp]

where i check this? in unity or blender?

[tough hound]

In Unity and Blender both you can see when selecting an object if it has non-uniform or big/small object scale
But you'll fix it in Blender by applying scale or enabling apply transforms on export

[carmine imp]

is this?

[tough hound]

Yes

[carmine imp]

where the scale? i only see apply transforms

[tough hound]

But it's also good to keep an eye out for each weird transform
It can lead to weird modeling behaviour in Blender

Scale is one of the transforms, in addition to position and rotation

This resets an object's origin points to 0 if position is also applied

[carmine imp]

you mean control A in blender right?

[tough hound]

Yes

For that reason you may want to only apply scale on each object with ctrl+A, if you have multiple objects

[carmine imp]

this is right?

[tough hound]

Yea

[carmine imp]

maybe I missed another object that I should scale

[tough hound]

Worth checking all of them

[carmine imp]

yes sir

i will checking all again, and reduces same faces

is 3m tris in unity, that a lot right? when i using realtime or mixed, it even increased to 40m tris

but in baked only 5m triss, my vr project still have 70 fps
