Animated Impostor

by FloFu   Last Updated December 07, 2017 10:13 AM

I need to create explosions and smoke, but as the particle does not interact with the environment (there are in the background) I was thinking of using the Animated Impostor technique (or animated textures):
Make the animation in Blender render it as a a bunch of images and render the animation either using a 3D texture (and updating the z value) either using a 2D texture (and moving the uv coordinates).

My concern is, the rendered animation represent about 25Mb of data (for a 512x512 pic with 30fps). So it might be not an optimized solution?

Is it the way to render animated textures?
