demo38 Posted April 3, 2003 Share Posted April 3, 2003 Doing an interior animation and have been messing with radiosity settings for the first time. The manual tells me that for fly-throughs, caching the radiosity solution will save time on subsequent frames, but I get longer frame times with each subsequent frame??? Any input on this? Also, where can you set the number of ray bounces? Thanks! Link to comment Share on other sites More sharing options...
Richie Posted April 4, 2003 Share Posted April 4, 2003 Hello I would sugggest to use BAKING THE RADIOSITY SOLUTION, instead of cashing it. You will really get shorter render times. Press: Shift+L (for activating a light), p (for the properities of the current "Object") and click on "GLOBAL ILLUMINATION"... Richie Link to comment Share on other sites More sharing options...
ingo Posted April 4, 2003 Share Posted April 4, 2003 Caching just stores the raydiosity solution, nothing else. So if you have longer rendering times they result mostly from the raytracer. Maybe you have a lot of reflections in your movie when the renderer gets slower or anything like more complicated textures or higher texture maps. How about posting some pictures ?

demo38 Posted April 4, 2003 Author Share Posted April 4, 2003 This is the first attempt at a radiosity rendering... It was first lit normally, then the switch was thrown. Radiosity Rendering I understand your suggestions, I was thinking about baking the surfaces, but what would be the resolution / steps I would need to follow so that the final would look as clean, and not turn out spotchy when mapped back on? Is this best to do the room as a whole? Or, break the room up into pieces, so that each object has it's own UV map when all is said and done? I followed the Baking Textures on the Cow tutorial on newtek's site, but one cow with external lighting seems different than a room with internal lighting. But, then again a cow with internal lighting could be interesting! Thanks, -demo Link to comment Share on other sites More sharing options...
dwright Posted April 4, 2003 Share Posted April 4, 2003 what version of LW are you using? the bug you mention about longer frames using cached radiosity was fixed back on V 6.5c (I think). Are you using V7.5b ? regarding ray tracing reflections, you can set it by changing the "Ray Recursion Limit" on the rendering options from 16 to a lower number. best regards, [ April 04, 2003, 02:04 PM: Message edited by: dwright ] Link to comment Share on other sites More sharing options...
demo38 Posted April 4, 2003 Author Share Posted April 4, 2003 No, Lightwave 6.5. Thanks. Link to comment Share on other sites More sharing options...
dwright Posted April 5, 2003 Share Posted April 5, 2003 That bug was fixed, you should get 7.0 or better, 7.5. David Link to comment Share on other sites More sharing options...
