Made a purple floor, hdr lighting DGS has no specular reflection, color white, a little glossy 2010-03-17T18:23:40+01:00 http://area.autodesk.com/forum/autodesk-maya/materials/texture-baking/page-last/ http://area.autodesk.com/forum/autodesk-maya/materials/texture-baking/page-last/#When:18:01:31Z Here's the situation... I have a building from Google Warehouse that I would like take the textures from and apply to a resurfaced mesh of the building. My question for you is... Is it possible to take a model with more than one material applied and bake out a color map to the resurfaced geometry? 2010-03-17T18:01:31+01:00 http://area.autodesk.com/forum/autodesk-maya/materials/maya-fire-shader/page-last/ http://area.autodesk.com/forum/autodesk-maya/materials/maya-fire-shader/page-last/#When:18:36:41Z I have some geometry modeled as fire and I found this tutorial for making it look more realistic. [url=http://www.cgarena.com/freestuff/tutorials/maya/shadertips/index3.html]http://www.cgarena.com/freestuff/tutorials/maya/shadertips/index3.html[/url] I had a few questions though as I'm so new to mental ray. First, in the tutorial, he says to add a shader then add the respective photon shader. Then he says to adjust some attribute like "mode" or "height". Both have that property. Should I be adjusting both? Second, should I be seeing the effect without any lights turned on? I figured the technique would have the shader emitting it's own photons, or self-illuminating, but I get only black when rendering. Third, why does setting the refractive index to 1 make the geometry black? Shouldn't it become invisible? 2010-03-16T18:36:41+01:00 http://area.autodesk.com/forum/autodesk-maya/materials/misssfastskin---realistic-skin-tips/page-last/ http://area.autodesk.com/forum/autodesk-maya/materials/misssfastskin---realistic-skin-tips/page-last/#When:01:46:01Z Hello people! Anyone can give me tips and tricks to get better results to do a more realistic skin?! Maybe a better paint in photoshop or adjusts in lights or a post-production in ps too I´m using mr, Final Gather, GI, some lights environ with HDR and i believe a good adjusts in misss too. C&C are welcome Thanks, Marcelo 2010-03-16T01:46:01+01:00 http://area.autodesk.com/forum/autodesk-maya/materials/newbie-needs-fur-help/page-last/ http://area.autodesk.com/forum/autodesk-maya/materials/newbie-needs-fur-help/page-last/#When:21:25:23Z Hi there. I've been learning Maya using tutorials for the past month and a half. Now, I am working on a dutch rabbit and I'm having trouble with the fur. There are bald spots (which I didn't put there). I tried reversing the normals, but there was no change. The fur also is speckled, when it shouldn't be, but I think that's the lighting. Any ideas on how to fix this? Thanks! 2010-03-13T21:25:23+01:00 http://area.autodesk.com/forum/autodesk-maya/materials/volume-shader/page-last/ http://area.autodesk.com/forum/autodesk-maya/materials/volume-shader/page-last/#When:22:56:41Z Hello everyone. I am currently trying to make an object that looks like it is full of jelly, or water, or something like that. I am working in mental ray and there will be lots of this object, so I would like to keep render times reasonable. Think of a cell that is filled with little bits of stuff floating around in its cytoplasm. So what is the best way to achieve this and keep a "realistic" look? On a sort of related note. I found this http://www.dl3d.com/index.php/en/products/mentalray-volume-texture-shader.h... Take a look down the page at the videos. That sort of thing would be great, but his product is not yet available. Any idea how to achieve something like that? Thanks in advance! 2010-03-12T22:56:41+01:00 http://area.autodesk.com/forum/autodesk-maya/materials/alpha-channels-not-working-in-mental-ray/page-last/ http://area.autodesk.com/forum/autodesk-maya/materials/alpha-channels-not-working-in-mental-ray/page-last/#When:16:01:22Z Hi there, I have a tree model, it's leaves have a color node (picture of the leaf) and Alpha Transparency node (with an alpha channel map of the leaf) Using Maya software render, the leaves render out good, with the alpha channel transparencies working fine. When I render with Mental Ray though, the leave just look like square jpgs, showing the color maps in full with the transparency maps not working. Any ideas on what I'm missing here? (I already tried turning down the Shadow Attenuation in the Ray Trace options, that didn't work) Thanks in advance.

I want to make that nice graduation appears as steps of tone. Maybe 4 or 8 blocks of color tone. Does anyone know how to do that ? Or if you know of another way to achieve this result other than using the ramp shader, please let me know. Just in case you are wondering; I am trying to achieve this procedurally so I don't want to paint the stepped ramp. Thanks 2010-03-10T14:13:02+01:00 http://area.autodesk.com/forum/autodesk-maya/materials/fisheye-lens-shader/page-last/ http://area.autodesk.com/forum/autodesk-maya/materials/fisheye-lens-shader/page-last/#When:21:55:14Z Hi everyone I have been looking for a way to make a dome projection using Maya. I need it 360x180 degrees. One way is to put several cameras in diferent angles and then use a stitch software but it takes to long and one render for each camera, another way is to use a fisheye lens shader, but i have not found one for Maya 2010. I found one here http://www.pixero.com/downloads_mr.html but when i render the image it's shows me a black image, i think this shader was made for an older Maya version. Could anyone help me to get this done? thanks! 2010-03-09T21:55:14+01:00 http://area.autodesk.com/forum/autodesk-maya/materials/normal-map-issues/page-last/ http://area.autodesk.com/forum/autodesk-maya/materials/normal-map-issues/page-last/#When:02:03:29Z I'm having a first look at creating a normal map for a character model and came across the 'Crazy Bump' program which is really good. The issue I'm having now is that when I go ahead and attach the normal map to my model and render it, it looks like there is some kind of a wood grain running all over the model.. I've attached a screenie showing what I mean, but as this is the first time I've tried doing this, I'm just after some help with why it looks so strange and what I should do to get it looking correct?? I've also attached the basic texture map I'm using and the resultant normal map in case that makes it more clear as to where I went wrong.. Cheers. 2010-03-09T02:03:29+01:00
