|
| | | I'm rendering an image at 800x600 in POV-Ray 3.5 right now, on an old 400mhz (ouch!) computer. It's using radiosity settings Jeroen de Haan provided to me over email. I've done other renders with these settings successfully, that usually take about (...) (21 years ago, 27-Jan-03, to lugnet.cad.ray)

| | | | | I believe you are currently out of luck. The way radiosity is currently set up in POV-Ray 3.5, multiple passes are required. That may or may not change in future versions, but I'm not going to hold my breath. I have a 450 MHz so I understand your (...) (21 years ago, 28-Jan-03, to lugnet.cad.ray)

| | | | | | (...) This can be related to the radiosity technique which you are using when rendering. Are there any yellow objects near the white one? If so, that could very well be the reason. Fredrik (21 years ago, 28-Jan-03, to lugnet.cad.ray)

Lower settings (even 1) will speed up the rendering, but sometimes they cause gross artifacts that dissapear at higher settings. (...) MEGAPOV is (...) (21 years ago, 28-Jan-03, to lugnet.cad.ray)

| | | | Ok, so I figured something out. It's not the model I'm rendering or the radiosity settings that are taking forever, POV is hanging on _one_ part. A 1x2x3 panel. It was clear in my first attempt, so I changed it to white (Color15). Still hangs on (...) (21 years ago, 29-Jan-03, to lugnet.cad.ray)

| | | | You are probably going to kick yourself for this one. You're right about the color white, but it has to do with how you defined it. The rgb had one too many values: rgb <0.975, 0.975, 0, 900> instead of: rgb <0.975, 0.975, 0> :) Thanks for the (...) (21 years ago, 29-Jan-03, to lugnet.cad.ray)
