just my luck, my video uploaded without sound, so you have no idea what im saying... i made an animation with physics applied to show what happens when a blood clot blocks a vessel, trying to save it as a video and get it in after effects to include in a video project im working on for school. the blood clot particle shows up like it should when i click, but it doesnt show up in the video that i export... whats up with that? if anyone could explain what im missing id really appreciate it!

Ok, thanks for posting that new screen recording that helped a bunch.

First, very clever idea of using CH for this type of scene, nice idea!

I tried a similar setup with a collision and recording (actually I used the included Chicken Blaster scene) and I didn't have any issues.

Without seeing your entire project or Rig mode it's hard to say, but there could be a conflict with some parameters. I would try a couple things:

1) Open the Chicken Blaster project and record while holding your Left Mouse B

That's very interesting. Have you tried importing your Character Animator comp into After Effects via Dynamic Link? You don't have to export a video first, you can just import the CH project into AE then choose your comp. One caveats here: It will be slooow, but it will be a live link so you can quickly see if things are working.

Also, with dynamics simulations you have to start them from the very beginning of the timeline in order for them to run properly. This is just how most apps that perform simulations work. Try moving the playhead back to the beginning of the timeline then exporting.

If neither of the above suggestions work then lets revisit this and you might need to re-record your video with the sound.

Without seeing your entire project or Rig mode it's hard to say, but there could be a conflict with some parameters. I would try a couple things:

1) Open the Chicken Blaster project and record while holding your Left Mouse Button down. Drag this comp into AE and you should see the chickens. If you don't then something is wrong.

2) If you do see the chickens show up in AE then try importing your art into a new CH scene. Start with just the clot, remove all unnecessary behaviors like Lip Sync and Eye Gaze (this won't fix anything, it just makes your list of things to look at simpler), and don't add any extra Physics behaviors. Keep it simple and start with the Clot with the Particle behavior. Try recording that and see if it shows up in AE. If it does, then start adding your Physics to your scene to get your colliders. Test in AE again. If there's still a problem this process will let you figure out where in the chain the issue is.

thanks! for whatever reason, re-recording the scene worked, i was able to save the clip in AE. The CH physics stuff is really good for making little scenes like this!
