Strange Photometric web lights.

Q-Bix · February 29th, 2008

Hi,

I'm having some problems using photometric web lights. I'm using Vray 1.50 SP1 with Viz 2008. the scene is about 30mb with about 100+ photometric web lights. The ambient light is from a Vray Sky and Sun, with the sun at Z: -35m (switched off).

The lights were displaying ok. I had some ram issues and crashes, which Ive resolved (i think). I continued working on the scene then suddenly the lights started to cast incorrectly. Stopping abruptly at a strange angle.

Ive attached images showing before and afters. I'm not sure what the problem is, i could have changed a setting? Any help would be great.

Thanks

May be your exposure settings.

im not using any exposure settings, im using vray linear colour mapping.

Ive reverted back to an old version of the file, which is crashing 9 out of 10 renders but im at least getting correct lights!

Try moving the lights further away from the geometry. This oftens happens with me.
