I myself prefer the phrase "cynical and jaded commentary"..

does that count as a disparaging remark about mental images?

There isn't a standard mechanism in mental ray to deal with it. If such a thing was standardised then it wouldn't be a problem but as it is each (er.. both) 3d vendor cooks up their own solution.

 

There is in PRMan a standard mechanism for this but it took mental images 15 years to add REYES support to mental ray so I'm not really holding my breath on this one.

I don't understand this choice ! All the main 3d applications got a specular toggle for lights. They can't forget a such basic feature !

It is the same thing with the "mi_car_paint_phen" and  "mi_metallic_paint" shader too !
Mental Ray gives use the ability to render specular in a "pass channel" but it is unusable if the shaders don't handle specular correctly...

The fast skin shader was made by mental images. Specular/diffuse toggles for lights are an XSI specific thing that they don't support in their shaders, unfortunately.

Hello list,

 

Been using the fast skin shader a lot recently and i dont know if this issue has been discussed ehre before but:

If i uncheck speculars from my lights, it still renders the speculars in the surfaces using the shader. if i uncheck diffuse it still considers it for the sss and diffuse...The idea of setting up partitions and overrides to have speculars and diffuses separatelly scares me a lot.

Is it me or the implementation of this shader wasnt properly done on that?

Tech dudes help me out here:)

 

Saludos amigos!
