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!

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?On 13 Aug 2008, at 17:01, Ian Grant wrote: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...On 13 Aug 2008, at 16:45, Christopher Wright wrote: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 :Pattached is the fixed (at least on my ATI machines) composition <Plasma GLSL.qtz> Thanks for the tips!
