Mia architectual & design 3ds max render element

[junz]

i just notice that mia achitectual & design material have more compatible in 3ds max render element such light,difuse,specular,etc..

but not for the mia car paint material.. it is a bug??

[TravisM]

Both the new Arch & Design shader and Car Paint shaders included with max 9 have different parameters than the standard max material. The standard Max material uses a rather simple lighting model - diffuse color with specular highlight to simulate reflection of light source. And of course reflections of various methods.

The A&D shader uses a more physically accurate model - specular highlights are a function of the material reflectivity and glossiness.

The car paint shader handles specularity differently. Since it allows for a multi layer specular effect (sharp highlight due to polished glaze on top of a more soft highlight due to the metallic paint), there are more parameters to handle the specular highlight.

thx for you'r the xplaination i understand.. :) but cloud you tell me how to get the separate pass from mia car paint material as i do form the mia architectual & design material ??

Ahh. forgive me. I completely misunderstood your question. Unfortunately I don't know the answer to your true question :)

hi,

it is not a bug, it is autodesk. This is the same problem when you use fast skinn or glas physik (pen) and the mentalray material. Autodesk have only create a renderelements shader for the mia_shader. Can you see in the 3dsmax9.mi

declare shader
color "max_mia_material_renderelements" (
shader "mia_material",
integer "GBufferID"
)

gui "gui_max_mia_material_renderelements" {
control "Global" "Global" (
"hidden"
)
}

version 1
end declare


and the standart renderelemnts shader, work only this Max Material.


declare shader
color "max_StdRenderElements" (
integer "mode",
.....
...
..
.

at this time i have no solution.
