I’m using Hammer editor to make maps for a game and set all the meshes to use complex collision as simple, since manually re-making the collision for the whole level would take ages. Unfortunately, this causes a lot of objects to straight up phase trough the ground, especially when they move fast or have another object fall on top of it.
I tried enabling sub-stepping, but even at high settings things still consistently phase trough the walls.
As far as I can tell it’s caused by walls being infinitely flat and manually adding box or hull collisions solves it. Unfortunately doing it manually isn’t realistic and the automatic generation is too inaccurate.
I couldn’t find anyone else having this issue, so I’ll just mention I’m using Unreal Engine 5.3 just in case it’s something version-specific. I can also provide the specific meshes I used in the video, but the problem doesn’t seem to be mesh-specific.
EDIT: I tried enabling Continuous Collision Detection (CCD) on my mesh. Previously I didn’t try it because I thought it was a project setting, not a mesh one, but after enabling it on all offending actors that seemed to resolve the issue to a satisfactory degree
You are never wrong maestro Clockwork. How can you doubt yourself now?
You can set all of the ‘static’ level geometry / static meshes to Complex for now (also look into merging parts of the level maybe). But this may hit performance down the road. For now, just set-up a subset of the meshes that absolutely need physics to simulate, or cheat with kinematic (interp) movement. After a while you’ll get used to having multiple copies of the same meshes with different types of collision.
Complex as simple is the stup1dest thing one can do for videogames.
All the bugs - 0 benefits - 100% lazy.
Just generate collisions.
And for a floor, you usually want a thickness of at least 10uu - preferibly more like 100uu (1m) so you dont get issues later on, but minimum around 10uu.
You cannot automatically generate proper collisions for a mesh as complex as this. Manually adding the collisions would take much more time than creating the level itself. I don’t know what you develop, but I cannot imagine any studio (AAA or indie) would be fine with doubling or tripling their level creation time just to manually place collisions everywhere.
I usually appreciate everyone’s feedback, but please don’t write stuff like that because some newbie might find this thread in the future and actually believe you.
So, what you are saying is that you have never worked in a professional environemnet one day of your life, but you feel justified posting inaccurate ■■■■■■■■ online for the sake of just posting something.
Got it.
How about you try and generate collision hulls First, then maybe, after that, give your learned opinion?
And btw, you and every newbie can actually do this In Engine - assuming your mesh is not trash, which given your “opinion” seems evident it is.
