@bluelunar @snuggans @MArdA TaleWorldsIf it bothers you guys enough, you can fix it yourself, edit the particle_shading.rsh file found at
C:\Program Files (x86)\Steam\steamapps\common\Mount & Blade II Bannerlord\Shaders\Sources
and change line 269 to:
pv_modifiable.vertex_color.rgb *= colormap * colormap;
So far, I haven't gotten the error again, but haven't had time to play too much yet or had many sieges.
