Lots of users seems to have tried to use the caustic features in YafRay. Now it’s my turn to try. Onestly I can’t say that I fully understand how YafRay works. For example, how do I get my glasses more transparent? The “Alpha” value is zero in the rendered image… I’ve tried to tweak the RayTransp values but I havn’t been satisfied with the results. The caustics seems to work even though the result isn’t exactly what I want, but it seems that only the green and yellow glass make a visible result.
