Well done Hervé. Impressive!

i think the framing isn't so exciting, but the vase itself man, just rocks!
great texturing...

he he..thanks for taking the time Tom.. you're da man.. ! thanks a lot Maxwellians.. I try my best... but this is nothing... watch what's coming hehe.. nahhh just kiding...

pretty simple setup.. vases have 2 bsdf layers one with a color texture (reflectance) and Lambertian.. the second is roughness 5% with nd 1,2..

weight for the first layer is 85%, and second is .....15% ...

for the floor, I am still looking for tat white paper that would help me more to understnad the wood lighting reactions... fact is that raw wood itself absorbs a small amount of varnish...

for now the floor has 3 bsd layers... I'll get back with a better solution...

I am asking myself if it is possible to make specular/reflections fade with distance in Maxwell.. is it not important..? Tom, How would you do it...?

Max... you've never seen that or remember it...? I thought it was a link on CGchannel or cg architect... ahhhh where's that link....??????

holy freholey ! ........Herve, what the .... !



Tom .........excellent post work. ....over the top.

still tweaking... no satisfied with the wood... If someone knows where I can find the link to real wood caracteristic stuff... I remember a white paper on that subject, and they were saying that wood is the most difficult to render... and they made a special shader for it... but I can't find back the damn link... Please if anyone remembers this... It appeared about 6 /8 months ago...

Can't help with rendering techniques, yet, but I'm very interested in realistic rendering of wood. If anyone needs close-up photos of a specific timber, I have lots of different hardwoods and softwoods in my workshop (even Ebony, Rosewood, Boxwood, also Ivory and "Mother of Pearl", too).

That would be a forced effect since it's already happening physically by many factors. However if you need to do it manually, a viewangle dependent gradient over the reflection map would work for it.
ivox: thx you exaggerate...hehe

Would be nice to see a wireframe of the scene.

...big point!!!

[Xlars]

Really beautiful and realistic render (and beautiful texturing) .. and thank you for sharing the settings. I hope someone can locate that whitepaper/description you are looking for, I dont remember haveing seen it.

[Sheik]

Extraordinary realism!
I would also like to know how to make a realistic wooden floor with the new materials. Maybe we can have a nice tutorial by Tom?

Should we not try to setup wood physically correctly?
(A wood texture with high roughness, and should we not set nd other than 1 to get a fresnell effect also from the wood itself, maybe just a small bump? Then we need a lacquer coating on top, with slight variations in thickness on different parts of the grain, Nd of lacquer is X, the reflectance color should be?)

This would be a good subject for a "Challenge".

[Hervé]

Thanks a lot for your kind words...

wood is indeed much more complex than other things... this is what I have found so far... but no really the one I was looking for...

www.cs.cornell.edu/~srm/publications/SG05-wood-lr.pdf

after reading this.. I wonder if it is really possible to make really really real... I think we need sss + diffraction..

Tom, thanks so much for you very informative trick... I am going to try it.. I have the feeling that wood blurs the reflection faster..

for now I am trying it with 3 bsdf layers... two for reflections one large reflection(Rough 46) over the tight reflection (rough 8..) the first containing the image ha rough97.. but I should also put some 1,2 /1,3 nd as I did for the 2 reflection layers.. I also placed the bump in the reflectance channels for the 2 reflection layers... one medium dark for the 0° reflectance and one light for the 90° reflectance... but both maps have the in-btween planks dark, in order to avoid now reflection in .... between the planks.. works nice so far...

we should have a wood challenge.... he he..

[Hervé]

here is a new render... I am still doing a new one now with a lighter wood.. here I try to simulate a Holland 18 century floor house.. it turns black because of heating devices (smoke) dark dust from candlelights, never washing... poor hygiena... so after a while it turns very dark + adding wax layers years after years gives a satin finish touch..

so here it is.. just a couple hours render... would need more for the dof..



and wireframe... I mean shaded from Maxwell
