I hope you dont misunderstand my words. I really love your skins
In fact, I use them (knight beta and hellknight beta) !
Those are very special, they remind me on Disciples 2 and 3 (a turnbased strategy game).
I really want to point this out.
Now back to the actual issues:
As I described it above. When I compare the "gloss" tga from beta with the final.
It looks completely different. In beta it has a black background and look very similar to the main tga.
In Final it is VERY white (thats why I see white body in-game I guess, when using gloss mode 1)
Why is there such a big differents ? The final tga was made just 10 days later.
Same with the "norm" tga. It has a complete different look:
In beta it is blue (background AND skin part of the tga)
in final it is white.
I am sorry, I dont understand much of skin making. Maybe my questions are silly.
The beta skin has no issue with gloss mode or parallax mapping. The final has.
Regarding the Hellknight:
Unfortunately its the same issue (cause it uses the same white "gloss" and "normal" tga“s i guess).
The 2 screenshots above were taken without parallax mapping and gloss mode.
One more thing for your understanding:
If you look at the high Res skins from Quake Reforged
: Quake Reforged
They also have no issue with parallax and gloss mode.
They are made EXACTLY the same way you used for your BETA skin
("gloss" tga has a dark background and looks very similar to main tga and "norm" tga is blue)
So I really think this is the rootcause for the issue.
