carlangas Posted December 5, 2005 Author Share Posted December 5, 2005 yes they are, all of them. actually my scene is no different from a previous one, the settings are all the same too, or so it seems. ive must have clicked something by mistake or something. i just cant figure it out Link to comment Share on other sites More sharing options...
dbarc Posted December 5, 2005 Share Posted December 5, 2005 have you got 'show calc phase' ticked for both irradiance and light cache - this may give you some visual clues.. Link to comment Share on other sites More sharing options...
carlangas Posted December 5, 2005 Author Share Posted December 5, 2005 have you got 'show calc phase' ticked for both irradiance and light cache - this may give you some visual clues.. i do, thats another weird thing. it starts calculating the light cache with all those little dots and it looks like it should not dark like the final image, then the other irr. passes. then the render comes out black.

C.Vestal Posted December 5, 2005 Share Posted December 5, 2005 We have had similar problems using latest build in Max8 Have not figured it out yet. Link to comment Share on other sites More sharing options...
Hao La Posted December 6, 2005 Share Posted December 6, 2005 How about 1st bounce, what did you use? check to make sure you turn on any Vraylight (?). Uncheck "loaf from file" in lightcahce, it probably load previous lightchace file which is empty one. Check to make sure "exposure control" in Max is OFF .

carlangas Posted December 6, 2005 Author Share Posted December 6, 2005 thanks for the replies guys. it was some geometry that was apparently causing this, I got its name off the vray message box saying it was overbright. I deleted that abject and now its working. thanks Link to comment Share on other sites More sharing options...
