I am using one of the preset 'big atmo' scenes from NWDA, called after the rain. The only thing I have changed is the final render resolution.
I've started a completely new project from scratch except using the sample sun file in the file sharing section, I'm slowly adding bits to it from clouds to water to land and hopefully i will find the culprit. So far render time for 900x375 are 2mins 48secs with sky and clouds and very little by way of noise. I'm goingto keep going.
Frustration is not cool, especially when you're used to having complex Lightwave scenes render in less than 20 minutes.
If anything jumps out at me by way of an issue I'll post it here.
Thanks
