Yesterday I started making a disaronna-bottle and glasses (an italian liqueur). I didn’t had any experience with blender but I thought that yafray is very good for glass renders. So I rendered it with some glass settings I found on this site.
But unfortunatelly, it didn’t gave a perfect result as you can see in the picture. There are a lot of dark spots (shadows?) and you can’t see the liquid in the bottle.
Any of you guys, know what’s the reason of this?
Model, lightening, settings maybe?
not sure what your are meaning about the liquid, but the black spots are caused by the ray depth. the ray depth sets how many surfaces the ray will go thgrough from the camera, befor it cuts off. To fix the problem, increase ray depth in the yafray tab to at least 5. i usualy use 10. this obviously increases render times however.
if you want light efects, add a spotlight traced onto the glass, then copy it and make the copy a photon lamp. change the causality depth to whatever you set your ray depth to. if you want better patterns, increase the number of photons.
