Hi EianNormally use Premiere.In recent months, I have little time to process the post productiona questions:
Hey you're welcome mate,Regarding the max ray depth, in order to understand a bit better how it works and if you need to set it that high here's what you can do.Grab the bike model from here,http://challenge.cgsociety.org/mari2013Assign a transparent material and experiment with "Refraction", "Absorption" and "max ray depth" settings..I think it will help you to better understand how it works and why it's there..Cheers..
