Hey everyone, I’ve been inspired by the images found on maxwell forum a while ago, a person rendering a photorealistic interrior. So I have desided to try same thing. The interrior has been posted on cgtalk and is a free model, courtesy of bryan howard. Sunlight Flash And the maxwell version (rendered by some one on maxwell forum) ---

Great result, I have already seen them on the two forums but yours are very good. 😄 And yes yours is more warm. are they QMC first and Lightcache second? ---

priad read above, yes qmc/lc, however I used dome light do get primary illumination and presicion in shadows, which is very time heavy to get with qmc, then qmc did the second bounce and lc did the rest 😄 Eric - 😄 Im afraid the render times are not archviz compliant 😄 ---

Also, a big part of this scene is maxwell to vray shader. I have done an indepth study (with help from vlado) of maxwell’s plastic and maxwell’s metal shader and have reproduced it in vray. The result, well you can see for your self 😄 ---

It’s much better than the maxwell one - it could use a little bit of sharpness but it’s excellent nevertheless. ---

I agree about sharpness… as in maxwell there is not filtering, so image can come out very crisp. I used quadratic filter. I suppose mitchel could do the trick. ---

render times… well for flash render it was 5 min on dr, but that would be 50 min on single node as to gi one, its qmc/lc with dome light at 100 subdivisions for noisless shadow, so it was 10 hours on dr, do the math your selves 😛 however maxwell one wasnt any better. Maxwell has rendered similar image in 40 hours and it looked like it needed another 60 so…here you go 😄 ---

Hmm, if I’m doing the math right the image rendered 100 h in Vray? ---

indeed 😄 this is however is equivalent to ppt…so such result is not a surprise. However a part of the slow down in my first plastic - 1 shader which was made of 3 shellacs a big nono…I think if i translate this scene into normal vray mat which is plastic - 2 in my lib, then it will be a ton faster.
