Hi all,
I'm finding some strange (to me) behavior between using the color_tex and rect_tex parameters on a LightRectangle. It also applies to LightDome and others.
I've attached a pair of files showing the difference and a couple images corresponding to the scenes. When I plug a checkerboard texture into the color_tex of a light, it seems to emit the texture onto all objects as though they receive planar mapping, regardless of distance to the light or other changes.
When I put the same checkerboard texture into the rect_tex (and activate the use_rect_tex) it gives the result I'd expect - a mixed emission between the two checkerboard colors.
I'm curious to know what the proper use of the _tex (like intensity_tex vs. intensity) parameters are and when I should use them. From the examples it looks like it's only used in the 06-ambient light example so I'm not sure if I should be using it elsewhere too.
thanks!
