A correctness release. The atlas now shows what your materials show, and

when a material cannot be carried into an atlas exactly, AtlasPro leaves it as

it was and tells you why instead of putting the wrong image in its tile.

Fixed (reported by a customer):

- Source textures as large as the atlas (six 4K textures into a 4K atlas) were

stacked on top of each other, so only the last item survived. Tiles are now

shrunk by one common factor, and the status bar says by how much.

- The Normal and ORM atlases came out black, and colours from 8-bit textures

were washed out in the saved file.

Also fixed:

- Missing maps take the material's own values (a fabric with Metallic 0 no

longer turns into metal; a solid-colour material keeps its colour).

- Node chains are computed exactly: Mix, Invert, Math, Separate and Combine

Color, Normal Map strength. Packed ORM textures (glTF) read the right

channels. Materials that need Bump, Mapping, a node group, a Mix Shader or a

non-Principled shader are left as they were and named in the Info log.

- Restore Originals button: materials, UVs and slots come back exactly, also

after saving and reopening the file.

- An atlas kept inside the .blend is packed and survives reopening; the

original materials stay in the file.

- A second atlas gets its own name instead of replacing the first; files in

the Save to folder and same-named images or materials are never overwritten.

- Linked duplicates are remapped once; with "All material slots" off the

other slots keep their material; the render UV map is the one rewritten.

- Alpha is carried into the saved PNG and the material; Emission Strength is

carried.

- Sharper downscaling; the padding lines up with the UVs.

- Works from Edit Mode; settings that cannot work are refused before anything

changes, and a failure half-way puts everything back.

- Trim Sheet, LOD Atlas and Palette assign their material and can be restored;

Palette matches each material by the colour it shows; Channel Pack no

longer writes a black AO channel.

- A texture with alpha whose Alpha output is not connected keeps its look:

Blender multiplies such a colour by its alpha before shading, and the atlas

was 4.4× brighter than the source. It now shades back to the same colour.

- Normal Map Strength above 1 follows Blender's own formula again (it was 7.4°

off at 2.0, and at 5.0 the stored normal pointed into the surface).

- An image you keep with a fake user is never replaced; a UV Map node naming a

layer the mesh does not have no longer sets the material aside (Blender

ignores such a node too); with Backup off the message no longer sends you to

a button that is greyed out; Restore Originals names the materials added

after the atlas that it drops; the LOD report counts tiles and materials

apart; colours clipped at 1.0 and a wide spread of Emission Strength are

reported instead of passing in silence.
