MentalRay render tryout 4 all

[mohamedberry]

ok, here is what i am thinking... i modeled this scene and seems i lost my powers coz i cant render it correctly, so i thought of sharing it with you guys to give it a try, no materials aplied to save file size, so feel free to apply any materials u like but dont forget to post its settings.

 

also dont forget to post your GI & FG settings... good luck and thanx in advance

ok, I'll try do something tomorrow.

Could I use VRay rnder for this? or it's only for mentalray?

The Topic is "MentalRay render tryout 4 all"

 

Just opened your scene and the problem is the units , did you model in real-world units ?. I will post the test soon

here's mine, hiding the glasses

 

 

Edited in Photoshop

the reflection on the floor is incorrect..

 

try smaller noise...

[Hao La]

there're a lot kind of floor , it's depended how its condition, new or old and its enviroment , with the huge window and lightning like that the floor is supposed to be like that. There's no noise be used

[TraP]

but i still thinging taht there is a problem with reflection..

[Hao La]

I think it's OK though , with the bg like that it will kick up the specular . But I still get your comments , thanks.

[mohamedberry]

well, i modeled it on CAD then imported the dwg to max... i'm sure i'm using correct units in max, but not sure about the CAD's.

anyway i gave it another try and here is the result i got.

it took 5:27 hours to render !! dont know why

[Hao La]

Here is your problems : the GI photon perlights is smaller than photon per sample and you gotta check off "use file" , and I still think about the units cause when 1st time I rendered it was like you did

[enigma]

Here are my settings

 

I set the scene so that only the main light generates the GI. Its decay is 1.85

GI photons 200000

Samples 5000

Volume 1000

 

No FG but composited with a AO (ambient occ) pass.

Render times: GI pass: 15 mins @ 1600 res.....AO pass: 5 mins @ 1600...both are reduced to lessen the noise. Post work in PS

 

[mohamedberry]

fantastic render guys... i fixed the units issue on max, and the photons too... but still got a dark scene

bryan can u please post more settings like ur sampling raduis & trace depth, actually if u print-screen ur settings that'll be eaier & much more usefull

thanx for ur time

Hi mohamed,

here are the printscreens. Hope this helps.

Btw, For the AO pass, don't forget to hide the glass. Put a white BG as well so you won't need to add an omni at the middle. thanks

[mohamedberry]

thanx bryan... i'll post my result tomorrow

[Hao La]

enigma : good settings , how about the AO pass , it repaced for FG right ? how you do it cause I ont know that much , is it dirtmap ???

[Atom]

Great rendering Enigma but i noticed under your exposure settings you have logarithmic exposure control checked. Is this a mistake or do you use this exposure control with your AO pass and GI pass.

 

Thanks

[enigma]

@ hao

Thanks man...yes it's a dirt map.

 

@adam

I used the exposure control for my GI pass only. to control the overall exposure of my scene. It's not usually the case but i used it for this one. Because of the large openings i found it hard to control the brightness so that's how i got through it.

Thanks

[mohamedberry]

ok here is my update...

i added one omni with ambient only to the scene to brighten it alittle, took a while to render though (1:55hrs). modified on photoshop.

[enigma]

cool man! a little smoothing tho but, i guess ur still workin it out. hope to see the final image soon
