I am making an animation(in cycles render) where object is converting from diffuse to transparent(with 0.9 value on mix shader). I am using branched path tracing (with square samples) Below is the rendering sample. All rendering is good except for the transparent part.
I am using Diffuse material with Transparent material(mix shader value changes from 0 to 0.9 in animation)
Its taking 2mins per frame. How to make it look perfect in this render time?
