blender vertex color import problem

Unity Engine

Please could anyone tell me why a blender 2.79 object having vertex color cannot be imported in my unity3D 2019.1.3f1 ?

thanks in advance.

here’s a blend with vertex color for example:

Are you sure they didn’t import? As I understand, unity does import vertex colors but Unity’s standard shader doesn’t use vertex colors, so unless you are using a custom shader that supports vertex colors, the vertex colors won’t appear.

I just tried to export vertex colors from Blender a while ago, they do export OK, you just need a shader that supports vertex colors.

no matter the shader ( even if i wrote one that uses Vcolors ) the thing is that the mesh is simply not imported at all when it has vertex colors.
Here’s the blender screen capture with vertex colors:

and here is what unity gives me:
for the asset:

and for its inspector:

Without vertex color list everything works fine:
for the asset:
5265687--526920--asset_without.jpg

and its inspector:

Please could you try to import the blend file i posted in my 1st post and tell me wether it works for you or not ?

Thanks in advance and happy unitying !

@grobonom Import FBX files, they work just fine. Is there some specific reason you need to use other format?

hi @Olmi

Because i use blender and fbx is not the native format for blender, and i don’t want .blend worfile AND .fbx export file, and .blend worked perfectly in the past ( with vertex colors, multiple UVs, blendshapes, etc… ) and don’t work anymore with vertex color in U3D 2019.1.3f1 :wink:

am redownloading the 2018.4.13f1 just to see wether or not it works…

The process U3D uses for importing blender files is to launch blender in background and ask it through a python script to export to fbx. The mechanism is just perfect as it’s totally transparent.

Unfortunately, in this way VCOLORS f*ck-up the import.
As you say, if i manually export an FBX from blender, the model with VCOLORS works perfectly but it’s just a too heavy workflow for complex scenes.

Did you try my blend file ?
does it import properly in U3D as a .blend ?

Thanks for your answers.

okay. This comes from blender side.

Devs are of the same kind in blender team as in u3d team…

yeeeeees it works !!!..
…almost…

:stuck_out_tongue:

My bad for having suspected unity3D ^^ :sweat_smile:
anyway in this forum, openning a blends seems to be kinda trauma :face_with_spiral_eyes: lol !

Note though that all things work perfectly with blender 2.79b !
I use a nightly blender 2.79.7 that has been fucked up probably by beginner devs ^^

Happy unitying !
