Hello. I am using SketchUp 2017 and Vray3.4.
I am now doing a caustic rendering test.
The problem of caustic sphere during testing occurred.
The first image is a caustic result by "spot light". - It is normal.
The second image is a caustic result by "Sun light".
- The caustic of sphere is strange.
The result is the same even if IOR of the refraction is given various values.
So I tried to configure the same scene using "Vray sun" in 3ds max.
"Vray sun" is equivalent to "Sun light" in sketch-up.
Is this a bug in sketch-up vray3.4? Or am I misusing it?
I also uploaded this skp file.
I am looking for help. Thank you.
