Combining multiple Substance Painter textures into one 

I'm so mad about this.

I was actually shocked when I ran into this issue. It's such a basic thing that I'm fairly certain they could get a basic version of it up and running within a few days.

One more thing, for the normal channel, because it's not all black, you have to use "overlay" instead.

@@segstron you son of a gun, that's right! I'm not sure if the normals are affected by overlay, but using difference is a great idea

Thank you so much for this!

thanks toyou and the OP! :D

@@segstron If the normals overlap from the bubbles overlay doenst work and this deleting thing might be better.

yeah, unbelieveable that it doesn't already have one after so many releases!

@@gherat even fbx exporter lol

Just make an id map man. Dont need to split the objects into separate pieces then.

Realistically it not common to spread out a single uv asset into multiple shader sets, but sometimes it's useful, like if your substance file is very complex and you would rather break it into a few pieces. Otherwise colour IDs are enough to break up the asset for texturing without making shader sets

Wait it breaks the UV map nvm damnit

Make sure you've set your dialation to transparent in the export texture settings

If you want to break up your asset into multiple texture sets because you don't want too many layers on one set, or if you're texturing different assets as part of a large texture atlas, then you'll need to combine the map after exporting them

Adjust the edge dilation pixels when exporting the textures. This will expand the edges as far as you need.

make sure you changed the dilation to transparent. Dilation infinate is what you probably have it on by default

Im not a max guy but I'm pretty sure yes, you can apply different material IDs to your objects in 3ds max

@@stefantom4 ok its about material IDs. thank you lol !!!! so that is easy.

5 months to notice this comment but yes, it will work, sry 😂

I wish but no. Thats why I made this tutorial. Hopefully one day soon substance will finally add that feature

Yea this process looks rough and would eat up so much time. Do you have better methods or apps that you would use for this issue?

Yep it should work fine. You just apply the combined texture (e.g. base colour) to any parts of the model that use it. You can apply the same material to multiple objects in marmoset. Hope that makes sense 👌

Stefan naw its all too complicated for me. i would never be able to get this to work

Stefan I need to basically convert all my texture sets to Udims

@@platinumpineapple9943 It seems lke your UV and texturing workflow is a bit different to mine, perhaps making things more confusing. TLDR: Multiple objects can share the same textures. Lets say you have a chair and a table. they are seprate objects but their UVs are on the same sheet (or same UDIM). You texture them in substance painter and export the maps. Because both the chair and table are in the same UV space you combine their textures using the method in the video. Now you have one set of textures. In Marmoset you make a material and apply those textures. That material can then be applied to both the chair and the table.

Stefan oh ok cool, thats wjat i need then, is there a way to get all 80 texture sets into Udims Within Substance Painter after I already textured something?

Stupid me. I can use ID Map.
