Hi, sorry, I was just guessing at possible problems. We have had problems with overlays and terrain texture units clashing, but I'm not sure it is related to particle system and terrain.
OverlayNode->setOverlayTextureUnit(1); Terrain texture units can in newer osgdem be set with layer option. In other code you can look for: setTextureAttributeAndModes(0,texture.get(),osg::StateAttribute::ON); jp CG wrote: > Hi, > > Sorry, I'm lost here, how do I check the texture units? > > Reards, > Cg > > ------------------------------------------------------------------------ > > > Date: Fri, 27 Jun 2008 09:17:59 +0200 > > From: [EMAIL PROTECTED] > > To: [email protected] > > Subject: Re: [osg-users] Particles being culled > > > > Hi, > > > > maybe check what texture units are used by terrain and particles. > > > > jp > > > > CG wrote: > > > I've ported Joseph's particle tutorial to osg version 2.4 and it works > > > perfectly on my side.
