Can't bake Material ID #184

Closed AspectofMaokai closed 9 months ago

AspectofMaokai commented 9 months ago

When i want to bake the material ID, it deselects everything and gives me this error message

Python: Traceback (most recent call last): File "C:\Users\PC\AppData\Roaming\Blender Foundation\Blender\3.5\scripts\addons\TexTools-Blender-master\op_bake.py", line 192, in execute bake( File "C:\Users\PC\AppData\Roaming\Blender Foundation\Blender\3.5\scripts\addons\TexTools-Blender-master\op_bake.py", line 315, in bake tiles.append( utilities_uv.get_UDIM_tiles( bset.objects_low ) ) File "C:\Users\PC\AppData\Roaming\Blender Foundation\Blender\3.5\scripts\addons\TexTools-Blender-master\utilities_uv.py", line 255, in get_UDIM_tiles nodes = slot.material.node_tree.nodes AttributeError: 'NoneType' object has no attribute 'nodes'

I understand you're using the latest TexTools release and you're on Windows. Could you upload the blendfile or a simplified version of it that still fails, with the selection you have before pressing the bake button?

having the exact same issue with the exact same error. tried a fresh blender install and new file and everything and still getting it. even tried it on a different computer and got the same thing. using the latest main release of blender.

I don't know how are you managing to trigger this error since all materials use nodes now even if the use_nodes option is set to False. I've just committed a possible fix, can any of you uninstall your current textools add-on and install the latest version from master, then test if this issue is gone and share the results here?

So the original issue is now fixed. If I understood you correctly, you don't get the colors assigned with Color ID or other method rendered in the Material ID bake. That is normal, the original design of the utility is like this: Material ID assign a unique, random color to each material in the scene. Some bugs made the tool behave not like that, but they were fixed recently. To get the same colors you have in your object baked, use Diffuse or Base Color baking modes. Watch out with the color space of the baked image. The other issue regarding selecting bake sets should be fixed now in master. If any other problem arises, please open a new issue.
