For example if you want to use a fileTexture for diffuse color in a mia_material_x then connect the fileTexture.outColor to mip_gamma_gain.input, and then connect mip_gamma_gain.outValue to mia_material_x_diffuse You can also use it when using maya shaders like blinn and phong, but then the hypershade swatch display will be incorrect. It still renders ok, but you would probably wan to to use maya's gammaCorrect instead in this case. mip_gamma_gain can be used for maya fileTextures and procedurals.

And another thing is i want to use the mip_shadow _reflection shader and other "hide" shaders in maya 2008,could you sent me a mental ray customNodeClass. mel of maya 2008 ,thank you very much!

Are you refering to the mip's or all mr shaders? Things like mia_material_x should certainly update, but the mip's do not, unless you modify mentalrayCustomNodeClass.mel Since you tried that already, it seems that you maybe introduced an error, which is very easy to do, believe me. Try renaming your modified file to hide it and see if the default shaders work correctly again when you restart maya. If you do suspect your edited file, feel free to email it to me and I will see if anything looks strange. There is a link to some unofficial mip hypershade icons on my downloads page - http://www.djx.com.au/blog/downloads/ Just copy them to your icons folder and restart maya.

I am using Maya 2009 x64 but all of my swatches are static. (very boring) I checked the mentarayCustom NodeClass file copied it like you suggested, revealed the internal shaders (excellent) but none of them have icons and they are all static. I put the line after them: return "rendernode/mentalray/material:shader/surface:swatch/mentalRaySwatchGen"; But ALL mental ray swatches seem static. Do you have any suggestions? Cheers, Paul David, excellent information as usual greatly appreciated.

Like how you figured out how generate swatches. Excellent Post, I will be trying this out. Like how you figured out how generate swatches.
