Hy there,
when I use the BumpMapController it seems that the bump-mapped surface does not react on any colors.
I extended the example TestBumpMapping by some lines to add a box and switched the lightning to amient red, but the texture still just reflects with light.
Do I need to know something about colors and bump-mapping that I don't ?
Or is the BumpMapController not capable of 'handling' the lights correctly ?
Thank you
