Adding new material on top of the model

[Paumonsu]

Hi. I'm pretty new to UDK so this question might be easy to solve but I have no clue on how to do that.

I'm making a RTS game from scratch, I've made the camera, mouse interface and selection. Now I want to highlight the selected actor, so I've created a fresnel material:



So, now that I have the material, how to I overlap it on the selected actor material?

Either you do this by using another mesh which is slightly larger, or you add the above instruction to the material that your units are using. To fade it in/out or turn it on/off you would then use a scalar parameter on the instanced material instance constant which is applied to the unit's mesh.

The secondary mesh isn't an option since I'll be selecting lots of meshes at the same time, so it's double the meshes to render. Is there any info on how to modify material values from code?

There are tonnes of tutorials discussing how to change parameter values using a MaterialInstanceConstant and Unrealscript.

Ok thanks. That's what i needed
