hi fellows
I've just rerendered a scene I have previously rendered in c4d with radiosity. Left one is obviously c4d, the right image is maxwell.



Now, I like the right one better, it is alot more natural. There are some
textures missing, but this is my fault, as this was just a fast test.
The only thing I absolutly don't like about the right image is the rendering
time... I rendered the left image in c4d at 1280x1024 which took me about
5 hours. The same image in 640x480 took me over 24 hours and still doesn't look finished... This is *so* frustrating!

I guess I just really need a new computer, my Powerbook G4 1.5 Ghz just can't cope anymore with such tasks. Still, comparing the two render times is kind of shocking.

What did you experience while working with Maxwell? I know my computer is not state of the art (by far), but can YOU render an image in
like 1024x768 in decent time (like 5-10 hours)?

Thanks for your advice
yves

I've had similar results with render times, although to be honest I like the C4D image better (apples to oranges). Nice job!

The wall I keep running into is image size. I'm still not sure myself what roll textures etc play, but I cannot render anywhere near the physical size of scenes I can in AR which is a consistant problem for me. Not only size, but render times increase substantially with file size, you think 640 x 480 @ 24 hrs was bad ... try double that, it will much more than double your render time.

There is some written here about optimizations also, with off-white whites, AGS, etc.

I have same experience with Maxwell. But you choose the worst situation for Maxwell. Your scene is lit only by indirect light and Maxwell is really slow in this case. I usually render such a picture 2 days. Try some exterior scene or studio scene first.
And one more though. Maxwell works like a camera. So how much MPix have your camera? 6 or 7MPix? So i render in high resolution, at least 3MPix and renders looks much better.

hi there
thank you all for your comments. It really seems to make a big difference
if your scene is lit by indirect or direct light. this is very similar to c4d. I guess you just really need to have patience with maxwell.

Burginger, if you're interested, I could render the same scene with just ray tracing. I don't know though how much you will see, the scene is only lit by a sky light and some assisting lights indoors. This is also the reason why the top left corner in the c4d rendering is so overexposed. I had to push radiosity strength quite a bit to get a scene that is bright enough.

yves,

For interiors such as this we all agree M~R takes way too long. I also have similar issues with resolution limitations, For now, I am limiting M~R work to exterior daylight shots, the exception being images where I am anticipating lots of Photoshop to achieve a cerain visual style and the rendering quality is not as crucial.

I really like your C4D render, with results like that you do not need M~R for interiors...
