Unreal 3 shiney shader problems!

easterislandnick

Hi, Is any one else as foxed by the material editor in Unreal 3 as I am? I'm trying to make a silver fire extinguisher, essentially a silver reflection cube map with an alpha mapped grime texture over the top of it. Should be pretty easy but I have a cube mapped reflection and a grime texture with an alpha channel but I don't know how to combine the two, any ideas?

I'd use a linear interpolate to combine the two

The easiest way to learn about this sort of thing is to look at another shader that does what you want. Have a look through the shaders in the existing UT3 or GOW levels.

Have you tried using a LERP? I think that will do what you want it to.

Just FYI, LERP means Linear Interpolation.

I'm not familiar with UE3, but typically you want to multiply your cubemap by a fresnel falloff, and add this to your diffuse.
