When the level starts up, they shoot off in the +X direction at an extremely high rate. The only reason I know this is because I placed one in front of the walkplayer and slapped a flicker cog on the 3do. Even still, what I saw looked a lot like a airport runway at night.

There are no other cogs associated with this object. Without the flicker cog it zooms off almost immediately after startup.

Any thoughts? I've never encountered anything like this before.

that is freaky.
You have NO sector thrust or conveyor cogs right?

Nope, none at all.

Try moving the player and object to a new sector way off to the side somewhere.

Do you have other mods being loaded by accident? Did you modify the player cog or any force power cogs? Is your force throw key stuck? I can't think of anything else.

No on all counts.

I'm going to try what GBK suggested tonight. If it's something in my level, starting another project from scratch with just a sector, the object, and the walkplayer should eliminate all of the other variables.

Tried it in both a new JK project and MotS project. Same result.

At least this eliminates anything in my level as being a factor.

Only affecting the following templates:
_debris
_debris2
_gravdebris

Those are parent templates... are you adding them directly or something based on them?

Was using the stock debris 3do's (ie, shrapnel2_2) that have those templates. I also tried adding a custom 3do with those templates. I think _throwable will work for what I need and my custom 3do is working fine with it, but it still bothers me about these others...

Check your resource directory and make sure there are no funny mods running.
