Hello again. First of all, thank you for your answers.
I forgot to mention that I tried with OSG 2.6 and newer versions (including the last one OSG 2.7.8). The problem seems to appear when changing from 2.4 to newer versions. It looks like some kind of change has been made from 2.6 and thereafter. Regarding the optimizer that Justin mentions, I am not using it, but I take notice of the issue. Thank you as well. Am I the only one who has experienced the same thing? Any ideas? Hi Sergio, Could you try the SVN or 2.7.8 dev version of the OSG as this has a fix to osgParticle. Robert. Hi everyone. I am working on a project that uses osgParticle::SmokeEffect and I have experienced a rare issue. Using OSG 2.4 I can add a node of type osgParticle::SmokeEffect to the graph, and I can put it under a PositionAttitudeTransform (or MatrixTransform). As expected, when the transform moves, the smoke effect moves along with it. The problem is that I need to update to OSG 2.6, and if I compile the same code with OSG 2.6, the smoke effect DOES NOT MOVE along with the transform, and stays at (0,0,0). ¿What has changed from OSG 2.4 to OSG 2.6 regarding particle systems so that their behavior changes? ¿Am I doing something wrong or missing something? If so, why does it work perfectly on OSG 2.4 and not on OSG 2.6???
