I put a scene to see how we can load animated textures for objects so we can use them with an object emitter for example. To see the script open the “Simulation Events” windows from Layout menu. The script will work with the selected objects. In the simulation Events you must change the “path_name”, “texture_name”, “extension_name” and “padding” variables if you want to use your own settings. Remember to put the “Use Texture” to YES in the object emitter before simulating.
