hii!
“oh noez not yet another lighting topic…!”
Since I don’t think this is related to the previous lighting stuff I posted I made a new topic. Maybe it’s just something I did not consider or forgot some code; the issue is following: I experienced that when I use large boxes, or imported models and scaled them larger => the light does not work correctly anymore. This may be a mistakenly wrong interpretation from my side because I guess it’s some kind of “shading mode” in JME:
In detail:
There is a small box on the left side and a very large box on the right side. Both boxes are in equal distance from the light source.
Picture 1: You can hardly see the large box on the right, but you see the nice red light on the small box.
Picture 2: Just to show that there really is a large box on the right. Again - only the small box is lighted.
Picture 3: Now that’s what I would have expected as a result.
Any explaination :?
