They seem to have
q3map_normalimage textures/sd_bumpmaps/normalmap_terrain.tga
in the base shader. This image isn’t included in the .pk3s or gamepack.
Was this something generated for each map, or a standard bumpmap for all of them ? :???:
Not having the normalmap to look at, I’m not quite sure what it added to the SD maps. The documentation on bumpmapping is a little sparse…
