I want to report a bug that annoys me for a long time. In some scenes when I use glossy refractions (like the one visible at left image on the ceiling), it seems that glossy material destroys Lightcache solution. During LC computation I get good result to almost 50 percent of status bar, but then LC calculation goes more and more to white dots. Irradiance pass then shows that no secondary rays from LC were used.
Resulting image is dark, with only first Irradiance map solution appearing in scene.
well. vlado will let you know how to fix your problem with your current version i hope however it does seem to be a bug but i can say the bug is gone in later versions.
All I can say is I opened the scene and hit render…and i got this: which seems to be correct result, then I went in turn off turn on everything I could think of and did not get the result as you descibe above…
im on vray 1.47.03 …so I dont know…
I rendered this via backburner - scene has animated camera with 6 views - 2 from those 6 frames are affected by this error. This error appears on every machine that got rendering job of frame 0 and frame 3. Same problem is when I assign that frames alone to single machine or just as a local rendering.
Da_elf, can you say what Vray number did you used for proper rendering ?
Morbid - I don’t understand how can you render this correctly on 1.47.03 - I’ve got error on this version first, so I tried 1.47.13 and error is still here.
im on max 7.0 and im not sure i can say which version. but as morbid asys he got it to render on his system. however one thing different between our rendering and yours is that green untextured object outside
OK - I tried to render scene in VIZ 2006 (R7 MAX platform) and guess what ?
Bug is not there in R7. So this ugly thing happens only when you are rendering in MAX6/VIZ 2005 environment.
Someone here using old R6 versions of our popular products ?
The only way to fix it that I know of if to ask Chaos for a more recent build. I think the problem is caused by materials with glossy refraction being close to or intersecting other objects. A PM or email to Candelero or Vlado might help.
I divided single frame into multiple strips (split scan lines) to isolate area with possible buggy geometry and rendered again. One strip was rendered wrong - it was frosted glass object being intersected by round pillars. So I made openings in glass geometry for columns to pass through.
Rendered again with strips - and bug dissapeared - one problem solved.
thanks a lot !
Anyway I am sending whole scene to Chaosgroup to further examination.
