Update 1.4.39

Minor fixes and updates

- Added support for 512×512 textures in generator and bake 

- Bake now restores original render engine after completion

- Bake now rebuilds a clean shader (UV → Image → Principled → Output) to avoid broken nodes.

- Unique names for baked textures to prevent overwriting

- Generator now auto-connects generated Checker/Gradient texture into the material
