CHANGELOG BELOW FO V2.3.4

Changes
Opening other layer image/vertex color as a mask no longer automatically set the source input to Alpha since the user doesn’t always want to use the image as an alpha clip.
Using Enable Baked Outside and Displacement Setup will use the combined normal as the final normal rather than the normal without bump. This is because displacement maps are not exportable using GLTF, so by using the combined normal, it makes sure the displacement data is at least already included in the baked normal map.
Bugfixes
Fix: Baking with Denoise/Dithering enabled doesn’t work with the latest Blender 5.0 Alpha
Fix: Alpha socket default value gets reset after enabling/disabling channel’s alpha
Fix: Max height on node input always gets reset to 0.1, causing a wrong bake result
Fix: Vector displacement input socket won’t get properly reconnected after enabling/disabling Displacement Setup
Fix Displacement image won’t get baked if there’s no layer using but there’s a connection to input displacement socket
Fix: Moving a layer with a transition ramp inside or outside a group can produce wrong color because of wrong connections
Fix: Baking other object data can spawn an empty image texture node on some materials
Fix: Wrong other object’s channel bake result for channels after Normal
Fix: Clicking Brush tool after toggling eraser with Smear/Blur tool will revert to using the eraser brush instead of the real paint brush
Fix: Error when trying to refill UDIM tiles with an empty UDIM image
