Rayfire in Unreal Engine

maestro · Sep 2009

Well it sort of took forever to get it working but its working. Thanks to Gizmosan for the explosion FX. Going to be doing alot of this for our lil project. Cheers!

What're we looking at here? Rubble pieces swapping in and being displaced with a radial explosion?

iWeReZ · Sep 2009

The initial explosion was nice, But it seemed a bit slow and weak :P

Like it should be quicker and more "Boom" rather than flow.

Still awesome.

Hey Adam, we are looking at a baked RayFire (http://www.mirvadim.com) animation working inside the Unreal Engine. Almost worthless for gameplay but awesome for cinematics.

That's pretty nice!

adam · Sep 2009

Ah thats cool. Valve used some baked animation for faked physics in Episode 2 (when the house explodes) IIRC.

maestro · Sep 2009

Thanks!

I saw that and wondered if that was dynamic. Mystery solved!

I think they used Blastcode, a plug-in for Maya, to make all the explosion animations.

You can improve it a lot if you add some particles as well

Ark · Sep 2009

Looks good, although i agree some particles and a stronger explosion would make it better.

There's a few good tuts here for what valve did:

Yeah the particles were an afterthought. The big thing was getting the 1300 boned skeletal mesh in there and working

Gizmosan is working on the dusk and debris fx

cheers!

HL2 Ep2 stuff is baked up to a point then it's passed on to the physics engine.

No, the explosions and collapsing buildings are all baked animation. You can look at the animated models in the model viewer and see that they're all fully animated. A lot of death animations for characters, especially in L4D, are animation that transitions to physics after the animation is finished, though.

Thanks to Gizmosan for the explosion FX.

its Lee3dee local folk

Nice job Dave!

That explosion is meant for the helicopter, I can make one for the building.

Ark · Sep 2009

On a second note, whats the advantage of using rayfire over unreals fracture system?

maestro · Sep 2009

with baked animation I have complete control over the scene. With unreals fracturing (i think you mean kactors?) I cannot know that the giant piece of building will be in that exact spot at that exact time to blow up that helicopter or smash that APC.

Lee3dee · Sep 2009

here's the explosion with the COG helicopter.

Looks pretty rad, but my only critique would i feel like there could be a lot more smoke and blackness and whatnot. Because a majority of an explosion is the smoke and tar look. I don't know if thats what you are going for or not.
