Thanks for your response, and advice, I'll give it a go. Wow, never realized you can really crank the settings up like that....I'll play around more.
I'm still a novice user, but the render speed of Redshift makes it very attractive to me, I also don't like the 'culture' behind octane but I fear once RedShift becomes more widespread, there'll eventually be 'us' and 'them groups...we'll see.
I'm determined to get better using this renderer. It also makes me realise the differences and potential of other renderers in general.
Nerv, your works are very inspiring, you've helped spark my interest! Thanks for all your experiments and posts!
