Actual tutorial now posted here -

*Sorry for double post, should have posted it here rather than in project show off, my bad*

I remember looking on Eat3D a few months back and I saw the material transition effect DVD. I thought the effect was amazing but I just couldn't afford the DVD so I tried to make the effect myself but without any luck.

Last night I was laid in bed though and I had one of those 'Eureka' moments, whacked open my laptop and had another go and I almost got the effect.This morning though I got the look I wanted, I have no idea how similar this is to Eat3D's but as far as I'm concerned it works just as good. It reminds me of the vampires dissolving in the movie Blade.

Note: Video is in GoW version of Unreal3 but it does work in UDK
Video on meshes:

Anyway, how to do it:

The Material


You then need to create a Material Instance Constant of that material, then add a MaterialInstanceActor to your level and link the two. Then, in Kismet link up whatever sequence of events you want to activate the material into a Matinee, in my video it was when the spawned actor died. Then in the matinee, create a new group and link it to the MaterialInstanceActor in your level, create a new 'Float Material Param', then create a keyframe on 0:00 with the value of 1, then create another keyframe however far down the line you want the effect to last and change the value to 0.

And there you have it. The effect can be added to anything really, it still needs a bit of tidying up, but I'll leave that to you.
