Ok I have been working on my first indoor scene today (room scene i guess) and I am using HDRI with radiosity to light the scene. I am pretty new to Cinema 4d and radiosity...

This is what it looks like right now (quick render with geometry AA), still some stuff to do. I cant seem to get rid of the blotchiness on the floor or the walls.

http://i158.exs.cx/img158/9024/rmx6mq.jpg

My Radiosity Settings are:

Strength: 100
Accuracy: 80
Prepass Size: 1/1
Diffuse Depth: 1
Stochastic Samples: 350
Min. Resolution: 150
Max Resolution: 350
Recompute: First Time
Identical Noise Distribution is checked

Color Correction Plugin Settings:
Gamma: 1.2
Contrast: 46
Brightness: 15

What should I change with my settings to get rid of the blotches? With the radiosity settings please have mercy on my computer. I am using a 1ghz computer with 512mb of ram:shrug:

Hopefully you experts can help me a bit. Also some critique on the scene so far would be great.

You'd need to turn up your samples about 5-10x, which of course would kill your computer. I woudn't try to light an interior scene with HDRI.

ok im gonna try to boost my samples as much as possible. I cant seem to get decent lighting using standard lights. Anyone know any tutorials that deal with lighting interior scenes?

just use a purely white material instead of a hdr map

Ok i upped my samples to 500, still not getting the results i want.



I would like to continue to use a standard hdri...i like the color variations that it is giving me.http://img220.exs.cx/img220/946/realcopy9up.jpg

I talked to a friend who has a 3ghz computer, and got him to render for me. I am gonna try 800 stochastic samples on his computer and see how things go with that.

if you just like the colour variations try increasing the gamma putting it in a filter shader, increase it from 1 to let's say 1.4 and blur the hdr map in C4D a bit. That will help a lot.

Is that supposed to be a window in the background or a wall of light? If it's a window, or even if it isn't, it would be nice to see whats going on outside the main scene. Maybe some sort of a city scene? Of course this would mean you wouldn't be able to use the HDRI lighting but you could then experiment with different lights. some nice contrasting shadows on the walls would bee nice maybe? just a suggestion
