Playing around with bin number of your model may help you in this case. The default bin number of models is 10. If you set your explosion to 11 then your explosion will have priority when they are at the same position. This will get rid of the anomalies, and will look better. Trust me.
You can take a look at osglogo for what to set in code, but I find it easier to do it inside the osg model (if that is what you are using). Models are prioritized by their group and not by polygon. I don't know of any better way to 'blend' particle systems. _____ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of DC Fennell Sent: Wednesday, September 05, 2007 12:20 PM To: [email protected] Subject: [osg-users] Particle Sorting Hello, I have several particle systems, which may be close to each other. Unless all particles emitted are grouped and sorted as one bucket, then drawn, I get visual anomalies. For example. If I have 3 smoke stacks (each a separate particle system) close together, and if an explosion occurs in the middle of the smoke stacks, it looks odd, i.e., the smoke effect may appear in front of the explosion instead if intermingled when the smoke overlaps, depending on your view. Running double pass does not help with this. The only solution I can think of is to use one particle system for all effects, then sort back to front. Anyone have any other suggestions? Thanks in advance
