Rendering Phong E With Transparency

[odubrus]

Hey all,

I'm trying to render a poly logo with transparent and semi transparent elements to an animation

The elements are textured with the phong e material and the transparency element is keyed however as soon as i render this none of the transperent elements are transparent!

Googling this i see that if you are using a file as a texture in 2008 Alpha Is Luminance should be switched on as this is now off by default however how might i resolve this problem with a regular texure?

Thanks in advance for your help

well you could connect the embedded alpha from the texture to a invert node and then to the transparency channel of the shader manually if you need to

even on a internal maya texture like phong e?

I realise this could be done with a loaded file texture but with maya's own phong e? sorry not in front of maya right now

TIA

Oh I think I misread your post... I usually do this sor tof thing in composite but it's probably possible with mentalray shaders

It is possible gmask

My incompetence lay in not also keying specular color

Cheers again for your time

well then I guess you need to create a separate shader that outputs in the color channel what you wish to achieve in the alpha channel.
