entities falling through patches

[grayman]

Has anyone noticed that if you bump into or walk over a movable atdm:* entity (bucket, shovel, coin purse, etc.) sitting on a patch, there's a good chance it will fall through the patch?

 

This might have something to do with slightly embedding an item into a patch, like a bucket sitting on a dirt patch and you embed it slightly for realism.

 

It doesn't matter if the entity's origin is above or below the patch.

That's a common phenomenon with the physics - not usually a good idea to embed like that. If you must, you might consider some little brush right below the thing to keep it held up, or something like that

Exactly. If the collision mesh clips into any geometry, it will fall right through.

 

When mapping, I set up all my movables to float a few inches off of it's surface. When the mission is starting, one of the cycles Doom 3 does before letting you play is it turns on physics, and everything drops.

@Komag/MD: There is also an issue with some models in that there origin are set either right at the base of said model or worse its below. This is causing models like jars and health potions to drop through shelves and the like.

The origin doesn't matter. It's the boundary of the collision mesh that is significant. If that clips into something, then it can't collide with it. The solution is to place the entity higher than it needs to be. Movable entities will drop down until they land on a surface on game start.

If you want to embed a bucket in the ground just use a model, not an entity.

 

(and if you give it a skin that replaces 'collision' with 'no draw' it will have better collision for things like dropping item into it, etc...)

Try finding if there's any key points where they fall through and try placing collision brushes theres. Or if it's not to complicated a brush you could put a lot of smooth collision brushes right under it.
