Hey Guys, Perhaps some material gurus can offer some advice on a problem I am having.
-First off take a look at the light path settings that I am using. These are the standard ones I use for an interior arch viz project I am working on. Normally however I have both reflective and refractive caustics unchecked. But because of using the glassware, I did enable it in this screen grab render
-This is only 500 samples … normally I render 3000 samples, so don’t be concerned about the noise
-The glassware in this render is just a single face…there is no “inside of the glass” so all the normals are facing outward. I’ve made sure to recalculate normal and apply scale.
-As you can see I am getting some black uglyness when the glasses are at a certain angle toward the camera. There are 2 glasses at each place setting, the blackness seems to occur when 1 glass is directly in front of the other in the camera view.
My question are
what would be the minimum amount of transparancy bounces I should try to correct the problem. (that’s assuming the problem is caused by too low of samples) ?
Based on the glassware only having an outside profile, am I really benefing by having the caustic checkboxes enabled?
3)EDIT Is there something other than transparacy bounces that is causing the problem? I just tested quickly 64 and it didnt seem to change… at least in my 100 sample qucik test.
