How to combine Substance Painter texture sets?

[Emre35481319zqck]

Hi,

I textured the model, which I created with 3 different material IDs and a single UV map, in the substance painter program. When exporting, I want to combine these texture sets into a single UV map. Substance painter creates 3 separate texture files even though 3 different texture sets are included in the same uv map. Isn't it possible to create the texture of this object in a single texture set? Having 3 different textures causes the file size of the project to increase, I want to avoid this.

thank you!

Hello @Emre35481319zqck,

Thanks for your message.

If you're using a single texture set, why keeping 3 distinct material IDs? You can apply a single material on your entire model and send it to painter.

This way, you'll have a single Texture Set containing your entire UV set.

because he wants to bake objects that are on top of each other and for that he wants to use mesh by name and to be able to use mesh by name he needs each object to have its material name, while all objects are on the same UV. In this case it is a huge problem with sbustane painter. It may bake your model correctly but it leaves you with a lot of material and that means a lot of textures.

Hello @David32729965dqib,

I have a feeling that it's more about what you want than what he wants. The bake matching by name from Substance Painter doesn't use Material data. It uses geometry's name.

Therefore you need to have similar names between your submeshes and not between your materials. Which means you can have a single Material ID for several submeshes if you want ; and that's why the bake matching by name shouldn't bring isssues with your Texture sets or UV Tiles.

No matter what he wants, you are not fixing the problem.
He is asking how to merge and you told him why not using single set.
It's like I'm starving to death because I have no bread. But you told me to eat cake instead.

Sorry if that wasn't clear enough, we don't have options to merge Texture Sets. All the UV preparation has to be done before importing in Painter.

I'm indeed trying to offer a different solution for the same result. So depending on the workflow, using bake by match name (as instance) is in fact a solve.

Best regards,
