IMPORT OBJ SEQUENCES
1. In the Element Scene Setup, go to File/Import 3D Sequence
2. Select the first file in your animation sequence
3. Click Import
Once imported, under the model options you
will get some options for Start Frame, End Frame,
Frame Offset, and Playback Speed.
You can use the Start frame value to do a quick temporary scrub through to see if the whole sequence is there (make sure to put back to 1).
Once you hit Ok and go to After Effects, you will have some additional options under under Particle look.
