Back in time it seems Blender had an “image layers manager”.
I’m aware about some addons to manage paint layers BUT these are working on a shader level with textures/images (they stack several textures on top of each other in the shader and blend them with nodes).
I’m speaking about layers which was manged in the image level while painting on the 2D canvas (like photoshop).
Do you know if this system is still available in Blender 4? Or if I can find somewhere an addon which does that?
Below a print-screen of the system in Blender 2.62:
Blender never supported layers at image level.
Old addons were saving one image per layer.
That is a recurrent request to be able to paint different image layers.
Image Editor can open psd or exr files, just in purpose to display them.
But when it is about painting them, all their layers are treated as an unique one.
