Hi,
do you need the one inside the GLSL?
I need this clear patch - all is well when the settings are changed by
if the viewer window is resized I get garbage.
ATI Radeon HD 2600 Pro: iMac Intel Core 2 Duo
Nice bit of plasma by the way!
Cheers, Ian

wow, that is incredibly strange! Yea I recreated what you said and
it works now. Actually I didn't need the CLEAR patch inside the
GLSL, only the CLEAR patch in the RENDER IN IMAGE - and had to make
that like you say - level 2, enabled, but clear depth and buffers
unticked... quite strange. (THis is on Mac Pro ATI 1900 and MBP ATI
1600)... does this composition work for you or do you need the one
inside the GLSL? whats your hardware?

I deleted the clear patch and got the same as Chris - seemed to
work - but there was a triangular artefact diagonally across the
image.
Change the subdivision value and it goes crazy.
This is exactly the behaviour I was having...

For me (Nov 2006 MB, IntelGMA950) disabling the clear patch makes
it perfectly fine. So I'm guessing this is a bug. Also, tweaking
the source seems to make it flip out and do weird stuff for me.
Where you not getting the diagonal bug? At low or zero speeds I
couldn't see any difference, but when the plasma was animated
quickly there was diagonal artifacts, and while changing the
subdivision it would flash random images - just like Ian mentions...
scaleX and scaleY might want to go in the vertex shader though,
and pos should be a varying -- might make is a bit snappier, or
maybe that's completely wrong (I didn't look too closely at the
glsl code, I'm afraid)
Yea good point, I changed it and its included in the above
composition. Didn't have a massive impact, fps changed from 6.3 to
6.5 (with VBLSync disabled) - but I feel psychologically better
knowing that its a bit more optimized :P
attached is the fixed (at least on my ATI machines) composition
<Plasma GLSL.qtz>
Thanks for the tips!
