Hi osgUsers, followup:
been debugging the texturecubemap because it seems like it was the sinner. my debugging has brought forth that the texture given must be squared for cube-maps .. i did not know that.. the texturecubemap does some rescaling and when it does this it destroys all hdr values. Apparently the rescalling the texturecubemap uses can't handle textures with floats. is this correct?
