Mesh disapear when painting in Substance Painter

BlueAzure

Hello guys !

I have a really bad problem.

After create asset in Blender and create it UVs,
I exported the scene in .obj and made a new document in Substance Painter to texture it.
- But in Substance i can't paint on some meshes.
The part of the wall (and other parts) disappear when i click on it to paint.

I found that there maybe a solution in the TextureSet List box, but i don't want to change every time in it (because i can only paint on the one in selection).
Some people say it's because there is multiple materials, but in Blender there is no material choose.

- I remember having trouble with uv mapping (in blender) so i finally put grid texture (like on screen), and maybe i touch something.

I don't know what to do, and I don't want to spend my day making this asset again.

Thank you

It looks like you have indeed multiple materials affected to your objects, make sure a single material is applied to all your meshes that share the same UV map..

Thank you for the respond.

How i do that ? because in blender there is no material, and i'm new with Substance.

The reason the other texture set meshes are disappearing is because you need to disable 'only display selected material when painting' from edit>settings.

Thank you a LOT musashidan, it's work, but now i still have to change the layer in TextureSet List to paint.
This is the reason why i put my walls together, to make tileable wall texture. And i can't do this because i can't paint on multiple object in the TextureSet List.

But, thank you ;D
