Is there a car paint shader like the one used by MetalRay and 3ds max?

Thank you

not yet. most people use a fake reflection (environment mapping) for that -> http://www.coniserver.net/wiki/index.php/Cubic_Enviroment_Shading_Shader

Hi!

I'm having issues with cube enviroment shaders in a racing game too. I'm trying, without sucess, to move the enviroment texture following x/y coordinates. Example: in a racing game, a enviroment texture should move with the car's velocity. But according to the shader's logic in the link given by broozar, the material just render the first time and the texture still in that position.

Here's a piece of the code:

function mtl_envmap_view()
{
mat_set(mtl.matrix,matViewInv);

mtl.matrix41=0;
mtl.matrix42=0;
mtl.matrix43=0;
}

Using this code, I tried to change the '0' values to floatd(my.y*(-1)/10, 64) and that resulted in a empty pointer error. So I tried this:

if(me!=NULL)
{
mtl.matrix41=floatd(my.y*(-1)/10, 64);
mtl.matrix42=0;
mtl.matrix43=floatd(my.x*(-1)/10, 64);
}

With that, the game works, but the texture still static. Please, is there some way to make the enviroment texture move?

Thank you very much!

Not sure, maybe try this:

material EnvMaterial
{
event = the_material_function;
effect = "theeffect.fx";
gflags = ENABLE_VIEW;
}

I think if you want it to update every frame, you must add the flag ENABLE_VIEW..

Hope it helps, ^^

Thank you very much for your answer, Adoado! This didn't helped me with this problem, but it helped me to make some changes in the enviroment mapping to make it faster! That's really nice, you're great!! ^o^

But I'm still trying to make the enviroment texture move with the x/y position... I'm trying to change the matrix, but it still resulting in a empty pointer error. Does anyboy have a hint of how can I solve this problem?

Thanks, everybody!

np, glad it helped

Sorry, as for your other problem I have no idea
