applying shader to just a specified group

Hello all,

i have modelled a character with sunglasses. Now, i want to use the cubemap"shader"(FFE) for the reflection, and i know how to assign it to a whole model. But well, not the whole character reflects the environment, just the glasses. In the 3ds file/max file, the sunglasses are a single group, but not a separate model. (--> i do not want to use two models and attach em.)

How can i assign the FFE to just the one group? is there any script? is there any possibility to do it with alpha maps?

It's hard to implement, i think. Split your model: character and glasses, use two materials and attach one model to another with few lines of code...

it has to work somehow. this is really important for me, please anyone, help me...
Milkshape offers the opportunity to do it, but it won´t show up in MED.

Easiest way to do this is with alpha, you should probably look into the multi-texturing shaders on more info on how to use the alpha and then apply the effect...

Cheers

Agreed... Basicly it would function like a gloss map. Use full on (white) for the cube mapped parts and full off (black) for the non glossed parts and use that as a multiplier in the shader's specular calculation...

But, you originally wanted this to work with a FF shader right? hrmm... unfortunatly that's not in my scope... I'm still trying to figure out what FF's can do that I can't do with a basic (hand coded) shader.

Just wait for the next update. It supports external textures, groups and multiple skins for models. This should solve your problem (by long-term).

Attach a model !

alpha masked environment FFP

With the alphamap you deside about where the environment and where and how much of the skin shows up of the model.
