Physics Object falling through floor

So, I have a bunch of weapons and items, that all are Skeletal Meshes and have physics assets. The problem is that when I put an object on the stage, it sometimes drops through the ground. I can sometimes click the play button, and it will just fall through. I really do not know what is wrong, I set the collision, for both the floor and the item to Block All, and generate overlap/generate hit events. It does not fall every time, but sometimes…

Any help could be appreciated.

Thanks

Do you have Simulate Physics checked on? This would cause objects to be affected by gravity

Yes, but obviously I want them to be affected by gravity, but does using gravity allow it to fall through the ground? It would be quite inconvenient to have to create a new gravity system…

or maybe if it wasnt clear, I would like them to still be affected by gravity but they are dropping through the floor.

Did you set your collision preset and other collision setting proberly? And check if you have modify those setting im play.

Yes, yes, I have checked, rechecked and re-rechecked, set the collision profile to BlockAll, and it stays that way the whole time

Try enabling CCD in the details pane of the object and make sure your collision mesh fits your object.

Hi man , Check if the collision are setted as simple or complex,
because if i remember right : the complex collision per poly just fall trough the ground using physics…

This works perfectly, Thanks! If you put it as an answer I can accept it

Great stuff, glad i could help!

I’ve been suffer this for a long time you save me! Thanks man!

If this is happening with Market Place Assets, the issue is the Physics Asset, simply change it out with one from a weapon is working right.

I thought there was no fix for this. Thank you so much, you are an absolute life saver.

If anyone is using Physics Assets for collision rather than Box, Capsule, Sphere, etc. Collision components then make sure to turn on Continuous Collision Detection (CCD) in the Physics Asset too, otherwise it won’t work.
