I have a particle system, that is added as the source of the point density. The problem I'm facing is that when trying to render it as an animation the point density cube around the particles sometimes renders as a solid volume scatter shader, that is not my purpose.
I tried to clear the cache by taking the animation to the starting point and pressing play, and then rendering. This solved the problem when trying to render one frame and it renders it as a particle based point density, not a volume scatter cube.
Playing it from the beginning does not seem to help when trying to render several frames, and also did not help rendering it in sheep it.
What should I do to keep the point density cache clear so that it renders the particle point density and not the volume scatter cube ?
