Mental ray test renders (Update 5)

First topic message reminder :

Hello po CGpeeps and calling all MR masters and MR users...

I have done another set of MR render exercise in terms of Lighting and textures/materials. I am hoping our MR masters could give some pointers on how to improve this... I'll be posting finished output soon.

Please note that models are not mine but did a few adjustments on them. My aim is to concentrate on the Light settings and materials to come up with a decent render output with Mental Ray.

More Test Renders:
Office Scene 02


with PS blurring for DOF effects... napaglaruan lang po

Office Scene 01 - Another render exercise only. Just found the design online. This one's more on Indirect Illumination tests.. FG Point=4, Rays=500



with bits of PS (adjusted brightness & color)

BOKEH DOF
2nd Bokeh DOF with PS kalandian effects

Same view without DOF and a bit PS


Finally, my first Bokeh Effect DOF! After so many attemps. hehe I should be getting the hang of it by now, I'll be doing one more! anyway, the rendering time isn't good, took me the whole night to finish the render. The next one should be faster, I'll take the masters' advice, I'll lower down the sampling and sudivisions of some materials and we'll see how it goes. Sensyahan niyo na po ang mga flaws, sana makagamit na din ako ng magandang carpet later on, probably hair and fur... sana!


and here's the bokeh set btw, notice i have the focus plane at value 5000mm, which means, I focused far to the dining area to get the effect. Didn't really knew before how the focus plane works. The value you set is meant for the distance of the Focus Plane from the camera. Hope that helps you guys. Thanks to our Sir Logikpixel.


New Scene!
ok... test renders pa rin, but I'm a bit contented with the lighting, minor issues on materials...



(more views to come) tried to lower some samples but it isn't looking good... and I think I now know why I have that big shadow going on by the sides of the windows... I'll discuss with my new/next render solution...







I'll be posting a more descent image for my next update...

Image 1 (NO Post process)
Render setup: sampling min 1 max 16, no FG, default GI/photons
Render size & time: 800max px for 2 1/2 hrs (my PC couldnt handle a bigger size render for this set... or maybe due to my material samplings kaya po mabagal... Any suggestions or recommendations Masters?)
MR Lighting: 2 portal lights with 2-different mib blackbody assigned. 1 portal from window (exterior) and 1 portal from the inside.
Environment Setting: MR Photographic Exposure, Shutter Speed adjusted from 500-350 for brighter output.
Materials: Max10 Special effects: AO and sampling max 20 & 32 for Refraction and Reflection respectively.


Image 2 (NO Post process, some errors and unfinished material settings)
Render setup: sampling min 1 max 64, FG points=1, ray=500, Interpolation=300, Ave. GI photons per light (Light Property)=200000
Render size & time: 1500max px for 2 hrs (used my Office PC here, quite better than mine)
MR Lighting: 2 portal lights of with 2-different mib blackbody assigned. 1 portal from window (exterior) and 1 portal from the inside. MR sun + MR sky
Environment Setting: MR Photographic Exposure, Shutter Speed adjusted from 500-350 for brighter output.
Materials: Max10 Special effects: AO and sampling max 20 & 32 for Refraction and Reflection respectively.


Image 3 (NO Post process)
quick render with 1 portal light of with mib blackbody assigned, MR sun + MR sky



Comments will be appreciated. I'll be posting finished output soon.



God Bless po sa CGP!!!

recap:

If you have GI enabled, Importons and IP. Only Importons(together with photons) will be used (if a merge is specified for the importons param, while set to 0 for the gi photons param) and IP will be disabled.
If you have GI and FG enabled. Same as above.
If you have FG only enabled. Both Importons and IP will be disabled.

that ends to these workflows:

- photons only
- finalgather only
- photons + finalgather
- importons + photons
- importons + photons + finalgather (cool here is to use the 'Precompute Photon Lookup'.. so you'll have a kind of fg importance-drived)
- importons + irradianceparticles

FINAL GATHER, PHOTON & GLOBAL ILLUMINATION FOR FAST RENDER
•Turn on Photon Map, use Read/Write File, then render
•Turn on Final Gather, use Read/Write File
•Lower samples to 1/64 - 1/64
•Render active time segment at every 10 frames
•Turn on final gather Read Only (FG Freeze)
•Increase samples to 1 - 16
•Turn on Save File for Render Output
•Render active time segment at every 1 frame

GI:
I set the Maximum Num. Photons per Sample to 100. This is so low because I also use a low number of photons per light. There is no need to shoot so many photons per sample when I am using such low photons per light. The important thing to consider when calculating GI is being able to light the scene evenly, and get a consistently lit space.

I also turn on Maximum Sampling Radius. I start with something small like 1’ and increase the amount by 5’ until I get a generally smooth result without seeing any discs in the rendering. Often I will go up to a value like 30’ before I get a smooth result. This is not a typical use for GI, and in a way it’s cheating your photons to get bright values with such low numbers so the render times are fast.

FG:
I slide the FG Precision Presets all the way to the left to Draft setting. I’ve found that I can get away with low FG settings if I add an occlusion pass later in post.

For Diffuse Bounces I set it to 2 typically, just to I can get enough bounce and increase my light values. Changing the bounce number significantly reduces rendering speed so be careful with this one.

I didn’t change this setting, but I’ll mention it. I sometimes change the Noise Filtering from Standard to None, if I can get away with it. When set to None, the render is much brighter because you are taking into consideration all of the FG points, but at times will have noise. When you set it to Standard the scene is much darker, but smoother generally. So if you can set it to None and still get smooth results, then you just got more light into your scene for free.

Thanks sir jay, glad you like it inspired lang sa mga gawa niyo hehe

bro, salamat sa pagbalik! Puro practice pa din e, go go go na nga ito

bro, ang layo na narating mo sa MR ah! ayos na ayos na ito!

wwwoooowwww. master idol salamat sa mga link. ang ganda ng gawa mo.
