There are many threads around on using yafray to generate caustics. I have tried to follow their instructions and generate a proper image, but failed utterly. Images are too dark generally and transparent objects are not transparent at all when using the yafray renderer. I am at a loss.
Could someone post a sample .blend file please that shows proper caustic effects when rendered with blender 2.34 and yafray 0.0.7?
PS: I will be gone for the weekend, but I am eager for your answers when I am back!
