Light Cache and IR map problem

[vlado]

The reasons for the invalid colors may be several: missing UVW coordinates (to a large extent this is corrected for the next release), invalid UVW coordinates (applying cropping to the bitmaps usually helps), the Ward BRDF in some cases (this is corrected for the next release), RPC objects under some conditions (they need some Reflection option on or off not sure which one).

... well im getting an overbright and invalid colours on every object in my scene all of a sudden ?

I too just had this occur. I have rendered this scene a dozen times and now all of a sudden I am getting massive overbright and invalid colors with the Light Cache. Once I get them the whole scene turns nearly white. I cannot figure out what I changed that caused this. When I revert the scene back the way it was when it last rendered correctly it is still doing it.

After much searching I fixed the problem by removing a displacement mod from an object that was intersecting geometry. I can live without it, and it seems to have resolved the issue.

vlado,

are there any other solutions to this issue? when do you expect the next release?

That particular thing can probably be solved by applying the "Crop" option to the scene bitmaps.

We had a scene here just recently that was having this issue.. I tracked it down to a single RPC plant.. (wtf?)

the real kicker is, it worked like a champ when the plant was in view, but the camera views where the plant wasn't visible the entire scene would turn up invalid, and the lightmap would just be completely red

The old keep Shutting off half the scene until you find the problem object trick worked..

yup, i went thru the model piece by piece until we isolated a revolving door was causing the problem.

thanks
