Mental Ray - Shaders

#3745

Cheers, the frosted glass is pretty much spot on, never thought to look at what was already there :slight_smile:

#3746

Hi this is a startā€¦very slow shader,because the volume shaderā€¦but seems like the I robot material:thumbsup:
hereĀ“s the .mat file and a sample image

#3747

Hey thanks, though your first suggestion of using the A&D frost pretty much hit the nail on the head.

Notice around the base of the breast the diffused translucant effect between the two surfaces, thatā€™s the kind of thing i was looking for.

Thanks again - Dave.

Hey Pixero, yeah I use your shader in maya software mode, its really bummers we cant get a better user interface in max. Perhaps Master Zap knows a solution? But Im afraid you allready talked him about it and there really isnt an easy way. I hope mental is going to make an official cross platform mi layered shader .

Hi guys, this is a fantastic thread, iā€™ve learned a lot from it. Iā€™m having some problems with this diffraction shader and i canā€™t seem to find any solution in here. Basically, why is there no .dll in the archive? what do i have to do with the files that are in there to make it work? iā€™m guessing this is the source code and it needs compiling or something, iā€™ve read that mental ray will compile them by itself but i havenā€™t a clue how to do it.

Does anyone have the Dll that i can use?

Any help is much appreciated!

The .dll is in the nt-x86/package sub-folder of that .zip file.

#3751

Awesomeā€¦ Thanks Jeff, this is a great thread!

hello i got 3ds max9 .but when i use mr sun & sky i cant use a hdri or anything else in my background,it replaces with somekind of gradient [even if i replace it it still reapears in reflections when i enable in :exposure control-logarithmic-outdoor lightning or something like thatā€¦]ā€¦i tried the normal skylight,but then,the reflections look burned in the bright spotsā€¦ some help!!!

Hello, Iā€™m kind of new to rendering. My renderings always suc because I donā€™t know what Iā€™m actually doing, lol. Iā€™ve been trying to improve this past month reading about light and what not. Iā€™m a pretty good modeler.

All I do is model cars and I'd have to say I'm 6.9-7.5 in the skills department still a long way to go but I can honestly say my cars look like cars :buttrock:and not as lumpy as when I first started. :thumbsup:

I really want to learn how to render realistically and I want to do it with MR. I want to give those vray users a run for their money. So if you give could give me pointers it would be cool.

Asphalt Rendering.

Again I really don't know what I'm doing here so... lol Here is something I render last night. I think it looks cool. Not the best but its a start. It looks rough and dry, which is what i was kind of going for. I use 3 point lighting but I really didn't spend a lot o time doing so. Each light has different intensities, as I read real world has to define the form. Mr Area Spot.

I use Arch & Design Mats and put an asphalt text in the diffuse and gloss, again dopnā€™t know what Iā€™m doing :). Just thought it made sense. Turned the roughness up, made sense to do so. Turned on the Amb Occu. Turned on Hightlights + FG to get rid of the reflections ummmā€¦ its dirt lol lol soā€¦ it sounds correct to me. Sample rate is 1/4-16. FG on but on Draft preset. Bump map is at 3 or 2. Thats is.

I believe I know how to fix those jagged shadows edges but I donā€™t understand why its shaper in the center but blurry on the edges. Iā€™m guessing it because of the Area sample rate which is 5x5, Disc.

The texture is pretty lo res but its coo. I did Photoshop it a bit with the curves because it was bit dark but only a bit.

Again it look kind of real to me because its just look harsh and bone dirt. Its not smooth looking.

Iā€™ve added instructions on creating custom A&D presets to my blog for those that are interested.

#3755

Hi Jeff,

how could you do something like that when the officials of autodesk allways pretend that itĀ“s not possible. ThatĀ“s not fair :bounce:

And now the serious part of my message:
:thumbsup: thatĀ“s what a lot of people have asked for!

Thanks a lot

Great work as allways

Hey the dlo file for geolights is not workingā€¦ I am using Max 9 32 bitā€¦

#3757

You need this one:

Dave

#3758

hey how come the geolight does not take the mapping or colors of the mesh

#3759

Have you put this color in the shader Light_point youā€™ve affected to the omni ?

#3760

Hi Guys,

my first post on this forumā€¦

i had many problems with arch&design fast interpolate function, Red, Yellow, Blue Black in all colors what you want. Some error are fixed in Max9 Servcie Pack 1, other Problem are not fixed, but it gives solutions.

a) Transparency+BitMap+Fast Interpolate: solution -> donĀ“t use a Bit map in tranparency color, only in cutout slot.
b) selfreflection + fast interpolate: is fixed in service pack 1
c) Hair+Transparency+Fast interpolate: is fixed in service pack 1

those paint shaders in the blog are too good !can u post some settings or the mat. file??

#3762

the problem is that bump mapping with mr texture shaders dontĀ“t workā€¦if I use a standard texture like noise or celular the bump works fine,but if I connect a texture shader like whirly,the bump mapping looks crazyā€¦1st picture,correct bump with celular, 2nd pict,wrong bump with whirly

Thank in advance:thumbsup:

Hi Jeff,

As always you deliver superb shaders to the Mental Ray community. Thanks.

I canā€™t seen to get the microscope shader to work, theres no ā€œhairā€ when I render. Is that because I gotta model or use a hair plugin, or am I missing something,

Once again,
Thanks a lot for a splendid forum,

Fab

Iā€™ve tested and Iā€™ve not a probleme with shader ā€œarch and designā€ and bump cellular.
