Hi !

FBX file

Read/write needs to be enabled in mesh import settings

@slow lotus Assuming at least the screenshot shows the vertex color working in the shader?

[slow lotus]

yes, R\W is enable
yes

[serene gazelle]

Well I'm out of good ideas

[slow lotus]

thx for reply

[serene gazelle]

@slow lotus What's the "Shader" context in your vfx graph? Looks new to me

I tried to check your fbx but couldn't because blender doesn't support ASCII fbx files
Not that there's likely to be an issue with it, since the shader reads it as we expect

[slow lotus]

baking "animation" mesh island pivots to UV and sorting them by Y-axis

the shader spins around mesh parts, vfx graph is for Prefab easofuse(Curves, Gradient, BBox)

[serene gazelle]

Is there documentation for it?

[slow lotus]

if its on YT - its free =)

Thanks ^^
In this case I'd try to verify piece by piece that the vfx graph is doing what we expect it to do

First get it to use vertex color successfully in a generic vfx system, then vertex alpha, then confirm that the sampling of the mesh is correct

I'd also test separately the Shader block, but you might have done that already before hitting this issue

[slow lotus]

The author doesnt use vfx graph its my idea to add for flexibility and visual feedback

[serene gazelle]

Meaning you made the Shader output block?

[slow lotus]

yes, Context -> Output Single Mesh

[serene gazelle]

Okay, I was confused here

I'm fairly sure you cannot "bake" anything with VFX graph, at least not like this

There's no functionality to write data anywhere, that I know of anyway

And if you could this wouldn't be the way to do it

Color there in your output mesh block is a property, it's not vertex data like vertex color is

So the result is always just one color per shader, not per vertex

[slow lotus]

its a property for a shader
can i work further with it inside shader graph?

[serene gazelle]

You can use it like any other property you'd set from the material inspector
