Hi, just searching for comments on render times.
I recently purchased the 3D Fluff training DVD 'radiosity interiors' and found it very helpfull and interesting. The one issue (as most people seem to have) is the render time required for good radiosity solutions. My main reason for purchasing the DVD was my concern over the time my images were taking,(12-14hours) so I was a bit surprised to find that even the best in the business still have large rendering times.
The videos final render took 'only' 4 hours which is OK for architectural work but it was at a resolution of only 800x600.(480000 pixels)
I don't know about other people, but many of my clients want A3 printouts at 300dpi. (I know we can get away with 150 dpi usually) By my calculations (approx.) that is 4900x3500 (17150000 pixels) 36 times the 800x600.
I normally judge a render to be too slow if it takes more than 12 hours overnight and I can usually achieve this. If however I want to increase my quality and render at the quality 3D Fluff recommend, does that mean waiting 144 hours? (36x4hours) Even at 150m dpi that is way too long.
I understand that radiosity takes time, but having seen images from other programs, rendered at significantly shorter times, I worry about the usability of the C4D radiosity render engine. Maxon are always selling C4D as a great architectural renderer and I have had great results (with or without radiosity) but surely this rendering time issue should be investigated and solved?
Sorry for the rant, I'd just like to know other peoples opinions on this topic.
