[BUG-225208] Attached rigged mesh with "Full Bright" applied to textures with transparency and in "Alpha Masking" mode are not "Full Bright"

[sl-service-account]

What just happened?

Happens all the time.

What were you doing when it happened?

If a texture with transparent sections in it is made "Full Bright" and is set to "Alpha Mode" -> "Alpha Blending" it works as it is supposed to. Texture is bright and no environment lighting has any effect on it's color or brightness at all. However, if "Alpha Mode" is set to "Alpha Masking" this is not the case. It seems like it is maybe 80% Full Bright, but external lighting sources DO cause the texture to change color and brightness still. This happens in Advanced Lighting mode, but works correctly if Advanced Lighting is turned off.

What were you expecting to happen instead?

The lighting of a texture set to "Full Bright" with "Alpha Mode" set to "Alpha Masking" should look identical to a texture set to "Full Bright" with "Alpha Mode" set to "Alpha Blending".

Other information

1) I attached a screen shot of the issue in action. Both eyelids are seto to Full Bright. The eyelid on the left side of the picture is in "Alpha Blending" mode and the one on the right side of the image is in "Alpha Masking" mode. They are identical in "Color". Set at the same time in a color picker. External lights are brightening the texture set to Alpha Masking mode which shouldn't be possible with Full Bright turned on.

2) The objects in question that I noticed this issue on were on an attached weighted mesh.

I can reproduce. Left cube is worn rigged mesh. Right cube is worn default box. Same texture applied to both cubes & set full bright. Local light shone on cubes.

Both cube textures set to alpha blending. ALM enabled: https://prnt.sc/kirioq ALM disabled: https://prnt.sc/kiriv3 Observe no discernable change in texture brightness when ALM enabled or disabled.

Both cubes set to alpha masking with mask cutoff of 4. ALM enabled: https://prnt.sc/kirjkf ALM disabled: https://prnt.sc/kirjpa Observe when ALM is enabled, texture on rigged cube only is washed out.
