Simple Baker UDIMs

Recommended Posts

Hi.

I am trying to bake a highpoly mesh to a lowpoly mesh and i use udims. Uv Mapping is fine and it bakes 0-1 space just fine. I use ../someGeo_$(CHANNEL).tga to bake out the texture, and i figure i need some extra part (like .$F for frames) to bake the udims to different textures. I googled and found .%(UDIM)d but that seems for import into shaders.

how do i have to specify my filename to get the different udims baked to different textures?

Thank you

I’m wondering the same here. I don’t know how to bake textures from hi to low poly using udim’s.

I used uv layout to use some udim’s but both simple baker and maps baker seems to only support uv from 0 to 1.

Is there any straight workflow for baking the other udim’s or am I missing someting?

not sure about Simple Baker or Maps Baker since they seem to be processing some stuff using COPs I'd assume there may be some limitations when dealing with udims

however you can still use Bake Texture ROP directly to bake into udims or create your custom wrapper around it for simplified workflows

%(UDIM)d works fine in the last release of Maps Baker (probably simple baker too). My problem now is regarding the generated normal map. When I use UDIMs all maps looks nice except the normal ones. Even worldnormal are ok, but normals are mess, it seems like the different UDIMs are overlapping in all the normal maps generated.
