for reinhard tone mapping -

I normally set the burn until the brightest area of the scene has detail or just slightly whited out. Then leave postS at 1 and use PreS as a exposure control.

Now with indoor scenes with some outdoor, you may find the burn number maxed all the way to 10, if that is the case then you will have to move the PostS below 1 as needed.

Anyway I think it is a given that with indoor scenes, just like in real life cameras if you have a bright outdoor light coming in and your focusing on it, the scene will ether be right inside, but over exposed outside or vice versa

in your case possibly the sky is too bright, maybe try lower sun angles and higher turbidity. Also add surrounding objects to block the light as it would in real life with other buildings and walls etc

hey guys

thanks alot coolcoj for that advice. ok i re rendered last night, same scene just using only emiiters, values set to 150 and 17.5, once again it took FOREVER to resolve but the end product is my best so far, all i need now is curtains on the windows

lol that's pretty quick render if you ask me

what system are you running?

BTW stair legs not quite touching floor

erm... its long for me :O im running c2d e6400 overclocked to 2.8ghz, 2 gigs team elite ram and 8800gts. normally resolves much quicker. the floor legs actually are touching its just a stupid flaw in the design of them that makes it look like they aren't

ahh that's pretty quick then, at least for me, since I'm here on a P4 Northwood 3.2ghz

matsta:
btw, it might be kind of slow to render due to the high reflectivity of the walls.

lol ono, u mean the floor?

anyway i get wat ur putting down, im going to try one today wiith diffuse shaders only. except for the windows.

No matsta,
When you have a room with high albedo (fraction of light reflected), the light rays need to bounce around for longer. It doesn't matter if the material is phong or diffuse, it only matters how much light is reflected in any direction.

What colour are your walls (RGB)? Also, back to the sunlight/emitter issue, why not render two pics and composite? That's my last resort solution when everything fails.

reduce max number of bounces?

matsta · Post by **matsta** » Wed Aug 08, 2007 12:51 am

hmm thanks guys, will give the reduced bounces a go

this looks very promising and nice, especially the second to last pic you posted (the very clean one)

Reducing the max number of bounces will help, but bear in mind that is a biased hack
