View Full Version : Transparency

11 November 2005, 09:29 AM
Hey there:)

I can't seem to get this thing to work, so I am hoping that someone can point me in the right direction here. Anyways, here is my little problem.....

I have made a scene and have used mental ray shaders. What I am struggling to do is, to somehow connect a transparency node to my mental ray shaders. To be more specific, I have a few mib_illum_blinn shaders and a misss_fast_simple_maya shader. There is obviously no transparency that I can see on any of these shaders.So, with that being said, is there a way to connect a transparency node to those shaders?? I see that there is a mib_transparency shader/node. Is that the one I use to get transparency on my shaders without affecting the colour of my current shaders?? Thank you in advance and any help would be GREATLY appreciated :) :)

You have to plug the outValue of your base shader( Blinn lets say) into the Color of mib_transparency and then plug mib_transparency into your miMaterialShader of your Shading Group....


hope it helps

Me again...hehe...I have bumped into another problem:( I have managed to get the transparency to work, the only other thing that I can't seem to get right is the alpha channel??? I had an alpha channel before I applied the mib_transparency. Is there a way to be able to get that alpha channel back?? I went into my mental ray options and switched on Pass Custom Alpha Channel and it does not do anything. Any help regarding this will be greatly appreciated:)

Thanks :)

Thanks Fabergambis

It is what I am looking for but I don't have any texture assigned to it...So the alpha still does not work properley. Thanks anyways though.
