Virtual Texturing Feedback

[anonymous_user_90974100]

Hi, I am not able to properly import UDIM textures. VT is enabled and it is a low res 4x4 tile.

Right, I understand that UV origin is different for DirectX and OpenGL however the UDIM standard has been around for almost 10 years now and users expect their textures to read from bottom to top. Even softwares that support both APIs like Substance Painter and Designer have adapted to this unified standard.

I’ve attached my example files here for you to test.
These are just a few plane meshes (2x2, 10x10, etc) and 100 labeled udim textures.
If you load the textures on the 10x10 plane mesh, you’ll see that the images unfortunately don’t load upside-down and compensate for the different UV origin, as you describe.

Thanks for looking into this

I also tested with those files, but the texture 1001 is constantly repeated.
The expected size is 1024x1024 and is correct in the content browser, but when opened it is 256x256, so only 1 texture. But the path to other textures is also good.

Tested in 4.23.1 and 4.24.1

What am I doing wrong ?
