Nice detail on the glass.Any reason for not taking path + light tracing ?

simply because i get better results, i append an image rendert wie lightpath and i thinks this not works.
due the fact that i have one light i have activated the dlsc for bidir.

if i render the same scene with path, settings not changed i get this result-> attachment. no light(in bulb, no good reflection. its curious maybe i m doing something wrong in lightpath mode.

greets andre


addition: i tested a bit, and it seems that the light not travels through the big-glas-bulb.

You're using path without light tracing so it is hard to get the light rim. Also how about your light bounce settings.

hey ho,
lighttracing is enabled, my bounce-settings are all the way up to 12 on dif,glos and spec. photonmap on 20-bruteforce on 8 caustics cache is also enabled. the results are so strange compared to bidir. this is fukn me up...

makes no difference i tried this shadowcolorthing already.

One thing i discovered, of i disable all glasselements i get this lightrim. So i think the failure is in lighttravelling.

pathtrace-update!
i reassigned a new fresh glass material, and i get this lightrim. as far as good.
now i tick the rough-box in the shader, because i what to add some dirtmap on the glas, and the lighttravellin is gone no matter what value 0 -10. i think this isnt right. try it for yourself.

if i now switch to bidir, it renders correctly. maybe shader-bug?

increase the glossiness treshhold of the lightracing until you get the light rim.
