Material by element, Animate random seed?
show user profile  BishBashRoss
Can't seem to animate the random seed on this modifier. Anyone know an alternative technique? Trying to randomly cycle between a series of materials on a number of elements.

Bump.

Anyone done something like this?

The random_seed property is not animatable.
Can you give more details? There might be a workaround.

thanks Garp. Say I have a wall made up of 24 tiles. On each tile I would like to flash between 8 different materials randomly to create a kind of twinkling effect. Imagine a disco dance floor with changing random colour tiles. That's the kind of effect I'm after.

I thought this was going to be a piece of cake. Not really!
Or maybe it is and I'm not seeing it (almost 4am here). I'll give it a better look tomorrow.

Something which came to mind... make 3 or 4 copies of the multisub material ur using, mix up their IDs... then using a blend material of some kind, animate the blend value (step on/off blah)

just something which popped into head..

Materiail by Element - Seed isn't animateable but both Random Distribution -ID Count or List Frequency are so you shouldn't have a problem creating you dance floor effect using either.

Thanks for the help chaps.

mm8r it appears increasing the ID count beyond the number of materials I have creates a kind of random pattern, seems like an odd way to do it but there you have it. Thanks! :D

Is this all geometry? Might be easier to randomise stuff by using particles?

Glad you found a workaround.
I tried adding an animatable custom attribute and then a callback to change the seed but couldn't get it to work.
Ah well...

Thanks for looking into that Garp. Much appreciated! Reeves, I rarely consider particles but should probably be more open to considering them, so thanks!
