mib_color_mix connections ?
1 Attachment(s)
ahoi everyone!
I am currently experimenting with skin shading. Since my girl finally gets her own avatar version of herself I need to make use of misss_fast_skin_maya and misss_skin_specular. both shaders are about to be plugged into the mib_color_mix. but either I missed a thing or made incorrect connections to the mib_color_mix or it is a buggy thing (which I dont believe!) I added an animatedGIF to show the rendered results. despite the quality of my settings in this stage it shows clearly that with the mib_color_mix (only the misss_fast_skin_maya is stuffed into it right now, but it looks the same with a second shader!) the scattering effect is lost -> watch the ear on the left side. what I did is to simply drag and drop the sss shader onto the first slot of mib_color_mix. the connection editor shows: misss_fast_skin_maya (outValue) --> mib_color_mix (color_0) if I´d connect it to Color Base it will render completely black btw. I did a lot of reading yesterday but still can´t figure out how to properly connect shaders (in particular SSS shaders) with the mib_color_mix. can anyone please lend me a helping hand? many thanks in advance _falott |
hi again,
I realized that this mib_color_mix isn´t a shader mixer but just a color mixing tool. so...how should one be able to combine these shaders: misss_fast_skin_maya + misss_skin_specular other than rendering 2 single passes each time and composite them in photoshop? there must be a reasonable way to do this entirely in maya. any ideas? |
well.. obviously there is no thread anywhere on the internet which descibes the process of hooking up 2 mentalray shaders properly in a layered setup or I´m just blind. on the other hand why not use the Specularity tab within the misss_fast_skin_maya since it should work the same way as misss_skin_specular does. honestly said, by now I can´t remenber why I was searching for a way to implement the specular skin shader. I guess misss_fast_skin_maya must do the trick as well.

Did you connect the misss' lightmap to the color_mix's shading grp?

interesting question - no I didn´t. let´s try
doesn´t work either: // Error: *Fatal* (mental ray) : mental ray encountered a fatal error. The system may have become unstable. Please save the scene and exit Maya. // // Error: (Mayatomr.Output) : failed during mental ray rendering: mental ray abort // |
D: Yikes!
I did a blog post on this very same thing. http://gennyx.blogspot.com/2009/06/l...al-ray_02.html And I even went ahead and tried with the default color mix again, and it worked. http://i300.photobucket.com/albums/n.../colorMix1.png |
ahoi!
Funny, I came across both articles while researching, but didn´t read through all the text! I remember I had a good laugh tho -> ""....Initially, I tried just dragging and dropping it onto the geometry, the connection editor popped up, its not a material duh! So after that brain fart I tried figuring out..." because thats exactly the same what happened to me in the beginning. I will dig into your's and Jay´s explanations later this day. Thanks a lot for pointing to them again! |
