Hi, I am doing an architectural render. I am trying to make the 3d people just to look as a gray transparency sillouette. I have tried the surface shader and the map shader, but when i manipulate the transparency, in the render looks like a glass figure. Is there any other way to do this? or any other adjustment in the shader?

I don't quite understand. Do you have human models in the scene and you want them to look like grey cutouts or do you have texture mapped cards?

If you want to have a 3d transparency you will need to fill the mesh with some thing like particals or fog and make the mesh invisable..............dave

If you want the people to be grey and semi transparent then you have to set the refractive index to 1 so it doesn't bend light and look like glass. That is, if I understand that's the effect you're after.

The surface shader is almost there... so you could render out those figures in a separate pass and then just bring down the opacity when you composite it in photoshop or something.

why dont you render the characters on a separate blank background with an Alpha channel, then just make them gray in PS save them out as a targa 32bit. Also make the alpha channel grey so you have a slight transparency to them. Then just place the characters on 'cards' (poly planes)in the scene instead of the full 3d characters - it will save on polys in the scene and should render faster
