yes. download and replace Rook_SpecTeam.dds (in the same place where rook_albedo.dds is.)
If you want to change it on your own:
Open Rook_SpecTeam. Now you see a yellow image with some red elements (don't touch them) and very small areas with other colors. (these are the areas where the specific color of every god is set).
Yellow means: NO Glowing
White means: GLOWING
50% Yellow and 50% means: 50% Glowing... and so on!
So, when you make a yellow place white, it is going to glow in the game.
How do I find out which part is for example the head in the yellow image?
Open the XXX_Albedo and put the yellow image over it. Give it some transparency so that you can see the parts you want to change
(If somebody wants to translate this in real english he shall do it, and post it as a tutorial somewhere )
