Cloth collider not working in second part of combined Mixamo animations
-
I'm working on a caped superhero animation made up of a series of Mixamo animations. The cloth, belt and collider tags for the hero's cape work fine with the first t-pose animation but then collider tag seems to stop working in the second imported animation. The cape starts breaking through the character even though I've added a collider tag to the second imported animation as well. I've tried adding collider tags to the skin and rigging and that doesn't seem to make any difference.
Here's my process. First I import the FBX t-pose and add some body armor and a cape to the rigging. The cape has a cloth tag and a belt tag that connects the cape to the body armor which has a collider tag. I also add a collider tag to the Mixamo character. Then I add the animation as a motion clip with "Remove included animation..." checked to the motion timeline. When I play the timeline everything works fine. Then I merge the second Mixamo animation. Before adding it as a motion clip, I put a collider tag on the character. I de-select "Remove included...." when adding it as a motion clip. The problem happens when I add the second Mixamo animation as a motion clip to the timeline. In this part the character is more active and jumps around. The animations combine seamlessly from t-pose to action, the cape remains belted to the the body armor but the the cape moves through the character and his armor. It's as if the collider tag isn't working but also like all the weight, thickness and bendiness settings on the cloth tag are gone.
Any idea why this is happening and what some possible solutions might be?

Hi bad-blank,
It's good to know that your first one works nicely. That is a good start.
I'm not clear about the way you use Motion Clips.
The only thing that is of interest with the Animation Clips is the joint-based Animation and that the Rig you use always has the same structure and hierarchy.
To be clear, as a test, a not bind Mixamo Joint Rig should work fine with every Animation clip even if you put all of them in the Motion System timeline.Since you provide no files, it is hard to see what happens. (If you share (Dropbox, Google, Adobe, Apple, or Wetransfer cloud services only) Thank you.
.
Let's try this: use the Animation Clip that works with the cape and leave it as is in the timeline.Next, use the second clip (the one that causes problems) and place it behind the first. Move it slightly over the first (a half second or so).
The second one might need a Pivot object to match the last position of the first. Call up a new one and match it manually. Do not use the Create Pivot inside the Motion System for that.If the Animation of the character looks good, check the Simulation.
From there, we have the next look at it.
Cheers

Hi Dr. Sassi. I think I did exactly what you described. I overlap the second problem clip with the end of the first t-pose clip. The animation looks good in terms of the rigging flowing seamlessly from t-pose to the action sequence. When you say check the Simulation what do you mean?

Is there a way for me to send you a compressed version of the file. It only 4mb compressed.
On top of the cloth collider problem, It seems to take an incredibly long time to play. Like 5 minutes per frame. Is there anything I can do to speed it up? I've got a 4090 card w/ Intel(R) Xeon(R) W-2245 CPU @ 3.90GHz processor and 128GB of RAM.
Thanks,

Hi Dave,
Do you have none of the cloud services mentioned above?
I can set one up in the morning (Pacific Time). I wouldn't say I like to keep an upload link too long in a post.
I will have a look into it.
All the best
