Reflective Occlusion experiment

[shaneis]

Hello all,

 

here is my latest in a set of tests. Trying to fine-tune my Occlusion passes, and testing a "new" occlusion material that takes vectors from given light sources. The "ctrlOcclusion" renders are the newer shader, the "ReflectiveOcc" is th built-in mentalRay occlusion shader.

 

All rendered in Maya with mentalRay. I know the differences are quite subtle, though I'd like your opinions on which is the more "realistic" of the three.

 

Thanks,

As you say the differences are very subtle

My preference would be for the third, the little bit of extra contrast brings out the detail nicely.

hmm fairly subtle....

 

ill take the 3rd as well

 

not sure about the highlights on the tiles in 2 and 3, but the chrome stands out alot better in the 3rd

chrome is definately sharper in the 3rd image, very nice... not too sure of any difference between the first 2.

Thanks for the input guys, that's great news...the image you all chose uses the ctrl_occlusion shader, which uses set light sources to calculate the occlusion, not a uniform hemisphere as with ambient occlusion. The best part is that it renders in approximately 1/10th of the time!!!

 

I found it a MyMentalRay.com, not sure if you can get it for Max. Will post a link if I find a max version.

I'm a bit curious as to what may have caused the white specks on the tiles in 2 and 3. For that reason alone I'd have to choose image 1, although a ghost of the specks can still be seen in that image as well. I love the concept of shower with a buddy.....

The mystery spots... just reflections from the "lamp shades", but forgot to photoshop them in those two. A bit rushed at the time.

 

Yes, the buddy shower, I saw this done in a house I worked on a few years ago. Thought to myself, "now that's a damn fine idea." Must have made an impression on me, The "house" this render is from was meant for a secluded riverside holiday house...would be hard to go back to work huh?

I'm definately interested in that occlusion shader and the render times you acheived... I will definately be checking out mymentalray for a max version...
