Photometric Spoltight Probem.
show user profile  Cylon
I'm really baffled with this one guys. Last night I stard playing around with Photometric Lights and Volume light for this big scene I have stored on my brand new laptop, so I started experimenting with the lights in a new file on my desktop.

I got a nice result and decided to give it a go on my laptop in the new scene, by using the same settings, and I kept getting this horrible noise pattern with the volume light.

I then copied the file from my desktop over to my laptop to see what would happen, and it still gives me the samehorrible results.

If I change the spoltlight to 'isotropic' or 'web' it works as it should, but everytime I go back to spot light I get this same horrible result.

I am using noise in the parameters, but even without noise, when I create a brand new spotlight, I always get this same horrible pattern.

Anyone know what could be the cause of this ?

This is really doing my head in.

I've posted some examples below.

Just gonna bump this and ask if anyone knows of any good photometric lighting tutorials.

I've looked around on google and havn't found much. Any tips would be appreciated too, it's for an outdoor scene.... should I be using radiosity or mental ray, or both etc...

I had a similar outcome with some plain old omni lights, I think id just fiddled with teh settings too much and changed something i shouldn't. I never found a way around it but i just delited them and made them again, Not exactly a fix for you i'm afraid.

(I'm far from an expert at this so wait for other folks answers)
