Merging texture sets

[Mr Lawson]

I have a model with multiple texture sets but share the same UV sheet. Is there any way to merge them into one Albedo, one Roughness, one Metal and one Normal map in Painter? I'm using version 1.4.1

Hi,

I'm sorry, but there is not a way to merge the sets in Painter at this time. You would need to manually do this in Designer or Photoshop. You can use the ID map bake to create a mask that will help you do this.

Cheers,

Thanks :D

Im trying to do the exact same thing!
Im a noob, how do I bake an ID mask?
It's coming out black with no alpha :(

Hi,

To bake the ID map, you can use the bakers in SP. When you click the Bake Textures button, you will see the baker option dialog and you can choose to bake the ID map only. There are options for the ID map where it will take the material IDs and their color to create an ID mask. You can also choose to use vertex color as well.

Cheers,

Hi, is there finally a way to do it? I actually have 17 shaders, which means nearly 90 textures to merge in photoshop, which means that I will have to spend at least 3 hours doing this painful process... why do you allow to have different shader to be able to hide other part, if you don't have to possibility to merge the maps at the end... I feel like I just fell in a trap and will have to waste the time that I win by using SP

HI,

The workflow comes down to material management. If you need to reduce the textures, then its best to reduce the material count. For a realtime asset, you need to minimize the number of materials assigned to the asset for best optimization.

In Painter, you can only working with a single shader for all texture sets. We allow for multiple materials, but if you need to merge them in the end, its best to work with only one material and use masks to apply different materials to portions of the mesh. If you have multiple materials and the UVs overalap, you won't be able to merge them anyways.

When we support UDIM, we will have a workflow for merging texture sets.

Are you doing it manually using the lasso tool in Photoshop? You can just re-megre model into single TextureSet, replace texture sets with unique MatIDs, and then use them as mask to merge.

While I generally see the point I do feel like having the choice of import with multiple texture sets and merge at end would be beneficial. For example on of my co-students was working on a revolver model today and found out the hard way the merging the texture sets was not possible. He had mapped individual texture sets for all the physical parts of the gun and planned at the end to use one material for all the parts which where, albeit in different texturesets, placed so that the UV's didn't overlap. This was so that painting areas, such as the insides of the hull and barrel, by hand would be easier.

I'm genuinely interested how matter such as this is currently planned to be done from the pov of Allegorithmic. :P

HI,

If you are needed to merge textures, I would use a single texture set. You can then mask areas of the model using the Polygon fill tool or color ID map. If you need to hide parts then you could just add a fill layer with only the opacity channel set to 0. Since each material group is masked, placing the opacity fill will result in that masked section being hidden. Its not a perfect solution, but is an ok workaround.
