Lighting changes for L_SPOT between 1.0 and 1.2??
by Steve Meinel · in General Game Discussion · 09/28/2003 (2:45 pm) · 9 replies
The following code does not light the scene the same way between the 2 versions:
Here's a 1.0 vs 1.2 screencap:
1.0 is on top, 1.2 is on bottom. Did something break in 1.2?
Thanks,
Steve

Just as a possible pointer into what can be going wrong: calls to SetColorDiffuse() that use only a primary color (I.E. pure red, pure green, etc.) give colored lights, but they tend to be way over-saturated. Adding any other color at all (say, Color(0.8,0.01,0.0)) instantly flips it to pure white light. Thanks for looking into this!

If you can tell me relavant files to check, I can diff them vs. the 1.0 codebase. Thanks!

Hey, just touching bases... Made any headway here?If you can tell me relavant files to check, I can diff them vs. the 1.0 codebase. Thanks!

Well, since there's no support for this engine, I did what any semi-sane programmer would do. I rolled back to 1.0, and patched in the Corona Image Library, so I've got a solution to the stupid lighting bug, AND access to image formats other than TGA nd BMP.:P
