Identical crash, both versions.
Worked: New Feature, has never worked as expected (in this way)
Short description of error
Rectangular, power of 2 UDIM Tiles cause Blender to hang indefinitely (spinning rainbow of death) when attempting to render in EEVEE.
Cycles works fine, EEVEE will hang whether attaching a new image to a shader, or switching to EEVEE from Cycles or Solid.
Exact steps for others to reproduce the error
Easily reproduced from startup.
- Create new, generated, *tiled* image, make size non-square power of 2 (1024x2048 is an example)
- Add several new tiles (I add 4) to the image.
- With Textured View, or Rendered (EEVEE) selected, attach new image to 'Base Color' of shader.
- Blender should now be unresponsive, and will stay so (tested for 90 minutes).
Saving the image first makes no difference.
Complex scenes make no difference.
Square Images work very nicely.
This is a wonderful new feature! I have been using it (with square images) to great effect. I hope this little hitch in this great new workflow is an easy fix.
Thanks in advance!
