View Full Version : Distort Particle SubUV... UV?
04-23-2012, 01:56 PM
Is there a way to distort the UVs in a particle subuv node like you can in a texture node?
In a texture node you just plugin a "Bump Offset" into the "UVs" port of your texture, but it doesn't have any effect on the particle subuv node when I do this.
Thanks for any help!

bizzarely, despite the documentation suggesting otherwise, you can just use a normal texture sampler node with your subUV image and it should work (animate) fine in cascade. so you can then do your normal UV animation techniques too.

No that's not working, it's causing my sprites to pop when I use a regular texture node.

Hrmmm this is an interesting one. To this day I've never tried using bump offset with a particle subUV expression.
I just tried it on March 2012, I see the same thing as you. My guess (and this is total speculation) is that it's not supported because it'd be too costly / look bad when interpolating between the subUVs. You could just use the regular texture sample, but then you'd lose the ability to use linear_blend in Cascade.
I'm interested to hear if anyone else has experience with this . . .

Yeah that's what I'm running into on that.
