Is it possible to make light affect only specific objects?
I want to light up some objects in the scene, without ligting the others.

I don't think it is.

Do you have an example of what you want to do? It is possible, for example, to have a light shine on an object behind something, and only on that object, like this.

I wanted to light up medal but not hand. Since I don't know how to do it this is what I got. Kinda fail.

All gold medals look like that if you add them as prop_static in map, but it looks much better in loadout preview. Maybe it uses some cubemap for it, maybe lights. I don't know.

You could make its materials self illuminated.

Does the self illum work with Normal maps? Cause the medal is made with normal map.

If you mean with materials that have a bump map texture, then yes, it works just as fine.

I said it, I just render 2 times and compose in Photoshop, hehe.

But it will be not good for long movie, because it will take long time rotoscoping each frame. I'll try the self illumination thing later.

I believe there's a way to transplant the lighting info of one model to another using the Element Viewer, but I can't remember off the top of my head how to do it myself. I believe one of the cartoon horse people on Deviantart did a tutorial on it?

It's called pony, not cartoon horse, silly. Either way, if that's the case, that's another thing the Element Viewer can do which will surprise me at first.

The thing in the element viewer (messing with the illumpositiondag) only affects static map lighting, not projected texture lights.

Rotoscoping is the process of animating with live action footage as reference for each frame. What you're referring to is a photomontage, or photoshopping.

Like I said, add selfillum properties to the material. It's really simple.

Problem with self illum that it will be universal light across all model. In my model gold color and shape is defined by specular reflections.

I have learned one thigh though: this is the weirdest metal shader I ever seen in my life.

It looks good and realistic only if you point 3 lights with different angles at it (and looks bad in uniformily lit environment)

If I had to make movie with it, I would need to decompile model and make a better shader.

The shader is set in the material, not the model. It's the first line of text.
