Sound controle of materials?

tuxmask75

Anyone ever figured out a way to use Soundcue to control material attributes?

LMP

in what kind of way to control a material?

Butthair

Are you thinking of Physical Materials? Like when the player is running on wood, it should make a wood sound?

tuxmask75

Sound wave form that can control scalar parameters of a material.

tuxmask75

perhaps this is not possible...?

Butthair

I still don't really get what you're trying to do. Maybe it just sounds too abstract.
You want to use sound waves, i.e. form a sound file, and use those values to affect a material? I've never heard of anything like this in unreal, but if you know how to make custom materials nodes, maybe.

Is that what you mean though? Taking a sound file and using it's sound values to control a scalar param in a material?

tuxmask75

yes that's what I mean, also a friend of mine read that some university class pulled it off. he couldn't find the link though.

Butthair

Sounds like a programming task either way. I'm not sure of any way to do it through standard kismet.

Last option I'd suggest is to time it out based on the sound file

tuxmask75

yeah , its most likely an unrealscript job. perhaps a custom kismet nod.

tuxmask75

do we even have access to the sound engine? ...the sounds playing, the sound volumes, the sound lengths, and current output magnitude.

Wooooah.....this sounds super trippy. I imagine walls becoming warpy and distorted & different colors / materials according to wavelengths in the sound. Would love to see this in action. Kind of like an LSD trip...

I ended up using a boned mesh that was animated ( moving bones up and down) in 3ds max using a song divided up into 8 frequencies. In UDK I took the boned mesh height animation data and passed that info to a get location and rotation nod, after a few nods later the height data was used by the material parameter.

Would have been nice if we could figure out a way to do the effect real-time within udk itself so that changing the song could also change the animation procedurally.

Are you trying to do with with UDK or UE4?

I'm pretty sure you could do this with Blueprints in UE4 but idk about UDK.

tuxmask75

UDK

If you can get the wavelength in Kismet (I'm not sure how, but you said you could get the property) you could try something simple like this:
