1) Sounds like an OpenGL issue. Is this in the preview window, stage window, or emitter properties dialog preview? Whenever I have problems with particles showing as colored squares or something that doesn’t look right, I usually add an emitter to the stage, open the emitter properties dialog, then close it immediately by clicking “cancel”. That usually fixes it for me.
We didn’t make any changes in the way that particles are drawn in this update.
2) I haven’t seen this and really don’t know. It shows like this in the stage window, or only when you save output? If when saving output, it could be a pIllusionRender issue.
3) No there is no option for this. You have to change the end frame number manually to match the length of the movie.
