Introduction to Maya - Rendering in Arnold
This course will look at the fundamentals of rendering in Arnold. We'll go through the different light types available, cameras, shaders, Arnold's render settings and finally how to split an image into render passes (AOV's), before we then reassemble it i

Scene would not render correct anymore - Mental Ray

I have a scene that’s has rendered nice in v2010. But since I moved to v2012 all my materials are rendering black. I’ve relinked them, still no correct render.

Strange thing is that I see the materials with hardware texturing on and that they render with the Maya Software renderer.

I can send the complete file if needed. Please mail me.

I’m a beginner, so bear with me. I hope it’s a stupid thing ;-)

Thx for the help on this!

it works for me.
you have a ray type switch with a black hole pugged into the eye... if this makes no sense, you should maybe delete the shaders and start again. user added image

if you really really need the shaders, i could help you rebuild them.
tell me the result you want. what should it look like when its rendered? we can work it out.

This does not make sense for me. Sorry...
And since I have to work with other models with the same problem, I have to understand what's going on here.

who set up the shaders? cant they explain why they did what?

i changed the shader and light setup to get that to work. sorry i'm using a trackpad on my laptop to do this so i'm a bit slow. i'll come up with a fix, but i need to know what you want? do you want the alpha switching thing? do you want the black hole shader? if you just want a bog standard material i'd start again.
the ray type switch is cool, you can render different results for eye, reflection, refraction, final gather blah blah. it can be handy.

not having a middle mouse button or a right click is quite limiting user added image

all i can think of right now is try connecting your textures up again and then middle mouse drag the beautypass_mt to the eye of the raySwtch_mt.

i'll check this thread in the morning, and have a look at work.
cheers
