Even without camera+, it is noticable, but it only happens for ores using colors within a specific range of colors, such as red. You can also see it a bit on uranium, but it is less noticable because the secondary color is already close to gray :)

Darn. I'm sure you already tried everything. Well I don't use camera+ so the effect is probably negligible

Oh, and to comment on the color masking for ores issue, the problem is not because the pixel value gets "capped" from what I can see, but rather because of how the shader blends the alpha in the color mask. I have some modded ores with black rock and red ore. The ore on top is literally just dark grey, and the ore speckles on the side have the dark grey color around the edges.

So if it could be fixed by tweaking the "0" value color for the mask, it would not work either, cause either the whole texture would be tinted dark grey, or in most cases, tinted the secondary color used for the ore speckles.

My conclusion is that it would require a fix to the shader itself.

@holgast Yes, Vanilla Textures Expanded has textures for ore and stone walls. Oddly, they kinda forgot about the mask, which means their retexture still uses the one in vanilla, making ores look even more off.

With game art, sometimes you have to use an only 99% black outline to prevent artefacting. I wonder if you can do that with the graphic mask too?

also, does this need to be loaded after Vanilla Textures Expanded? I don't even know if it affects rock/ore atlases.
