The original development topic here.
In case you want test_light2, test_light3 maps to be displayed correctly, you need to uncomment | gl_RayFlagsCullFrontFacingTrianglesEXT
in ray_primary.comp
but this will create problems with shadows on other maps like cs_cbble, so delete comment only for the duration of the test test_light2, test_light3 maps.
For test_material, you need PBR materials.
For test_regress_template (and test_fog_* in the future), you need debug branch HLSDK.
Some maps are obsolete and left for history.
