Incorrect texture display

[usergithub64]

I installed the Trusty Pack Half-Life mod: https://www.moddb.com/addons/trusty-pack-half-life-1-v2

Map c1a0. In the original Half-Life, the textures from the mod are displayed normally:

In Xash3D FWGS, the textures are displayed incorrectly:

Is it possible to adapt Xash3D FWGS for this mod? Or is there some command in the console that is needed to display the textures correctly?

You need to open each problematic detailed texture, and remove the alpha channel in it. Then it will be displayed correctly in Xash3D FWGS.

It's detailtextures based mod or just some texture replacement? If it's detailtextures, maybe need change alpha channel processing for it. Something like pglTexEnvi( GL_TEXTURE_ENV, GL_COMBINE_ALPHA_ARB, GL_REPLACE ); pglTexEnvi( GL_TEXTURE_ENV, GL_SOURCE0_ALPHA_ARB, GL_PREVIOUS_ARB );

(this is for multitexture VBO detail rendering)

Separate detailtextures render is using GL_DECAL now both for VBO and legacy: https://github.com/FWGS/xash3d-fwgs/blob/master/ref/gl/gl_rsurf.c#L2482 https://github.com/FWGS/xash3d-fwgs/blob/master/ref/gl/gl_rsurf.c#L1099 Maybe try with GL_MODULATE?

It is using GL_DECAL + modulating GL_BLEND (GL_SRC_COLORGL_DST_COLOR), this means prev(1-alpha) + src*alpha, prev is missing (white) here. To ignore alpha, it needs just GL_REPLACE in texenv to get source on output and modulate on blend

It's detailtextures based mod or just some texture replacement?

This mod uses detailed textures that are displayed on top of the white textures from the .wad files.

So, GL_REPLACE instead of GL_DECAL would help
