Mental Ray - Shaders

#521

wo, you like it?

I’m gonna see now how to upload to the ftp of deetee, for the moment, another test.

rendertime: 47 segs

as before, no GI or final gather

bye bye

Damn nice look indeed DDS…the SSS effect looks damn cool. The surface looks somewhat to shiny tho in my eyes…

Anyways GREAT work…thx a lot!

folical9: Incredible Metal flake!

I’ve been trying on and off for weeks trying to get a metal flake material. I can’t wait to try this out and see how you did it! The ID people I work with have been on me for something like this and you’ve beat me to it (thank you, thank you, thank you!)

Your silver flake looks exactly like the powder coat I’m working with. I hope I can do something for this thread that will be half as useful.

#524

I updated the material over at The MR Uploader too!

#525

I updated the max file of the hand to that mental ray uploader as “hand_subscatter.zip”.

bye bye :beer:

#526

Cool, thanks DDS.

#527

You guys rock awefully.

#528

added a movie “hand_Subscatter.avi” in the mental ray uploader.

It’s only a test, but if you see it frame by frame, you may see some interesting things. It consists on an omni makin 360º around a hand, obviously changin the subscatter effect.

bye!

if i want to use glass luma, do i put it in my refective or refraction slot?

when i put it in my mental ray surface slot, i loose all my scene lighting, but it seems to render quicker!!

thx

you must put it in the surface slot of the mental ray connection.

If you put it in the reflection slot, you will only be using the reflection properties, and the same with the refraction.

I’m not sure if it works good even if you only want reflection or refraction properties…

I don’t understand why your scene loses all the light, maybe use mr lights? :shrug:

sorry, bye:thumbsup:

After downloading the glass cgtalk scene posted by folical9, i’ve not been able to make it look as sharp as the picture he posted up. I’ve changed the settings, but i must be missing something … probably something really obvious :shrug:

If anyone could help me out or point me in the right direction i’d be really grateful. Thank you. :slight_smile:

This is the original one.

This is my version which seems duller and not as sharp.

Just wanted to shout out my respect to everybody who has contributed to this thread :smiley: For the last 2 days (and nights) I have been reading and rendering like mad to get to understand Mental Ray. I find it incredible how a few well tweaked settings can totally ‘complete’ your image. Heres a small testrendered pic to show yall why Im so thrilled :slight_smile:
I dont want to mess up the thread so if you like theres some more pics when you follow this link.

Once again, you guys are doing a super great job and thnx a lot!
~Mike, happy 3D-dude

Wow 3D_Mike, that model and pose is great. I saw this in the WIP forum and loved it. The copperhead color one is awesome! How about a 1280x1024 (or larger) render for my desktop?

About the new metallic shaders. When I was making these, I had problems with the noise appearing correctly. I had to put a UVW map on my object and tile the noise map 4 times in order for the texture to work. I find it strange that I needed to tile a procedural texture? At any rate, if you guys put the metallic paint texture on an object and the “metal flakes” look smeared, then apply a uvw map and tile the texture.

I already wondered why you put the Noise to Explicit texturemap channel instead of object XYZ

Man, Id feel honoured if youd want my model on your desktop, after all its practically your clothes hes wearing :slight_smile: If you follow the link and wait for the pics too load, youll see its actually 1 huge (1 mb) pic sized 1280x2150. Just crop a model you like :smiley: This pose is just a temp though, you can see theres some interesections and I dont really like the head like this. Hopefully I can render some more original poses somewhere over the weekend. Drop you a mail if you’re interested?

Will do, and yeah feel free to drop me an email when you update the pose. Again, great job.

@DDS - yeah i figured, but i’m still having problems with my lights.
i’ve tried regular and mr lights, but still nothing. all i get is the reflections from my hdri.

have a look, top and bottom image with the same lights, red one side and green the other.

@3D_Mike- sweet bot, love the centre one, whats the render times like?

#537

stal3fish,

Put the metal lume into a standard materials diffuse slot and give that a try.

#538

yeah i tried it, it works, BUT it renders much slower

if i do glass, would i put it in diffuse to, hmm guess the refration slot would work!

thx

Thats because you are picking up the specular, and shadows (if enabled) now. For glass, I would just use either the glass (physics_phen) or the architectural glass, but thats just me.

Rendertimes are surprisingly fast. I havent really paid much attention to it but say 2 minutes a frame on a dual 1600, 1 gig ram. Im using 1 Omni with raytraced shadows and 1 skylight, final gather with only 50 samples and sampling quality at min 1/4 max 4. Ill do a better render as soon as I have some more time
