Hi everyone,
I’m new to Visual Components and currently trying to simulate a machine. However, I’m running into several issues with the physics. Parts don’t behave naturally, collisions look wrong, and the simulation doesn’t react the way I expect.

I’ve already tried adjusting the time step, disabling gravity, changing proximity volumes, and testing different settings, but the physics still doesn’t behave correctly.

Does anyone have advice on what I might be missing or how to troubleshoot this more effectively?
Thanks in advance!

Hi,

I don’t think your machine needs to be#InPhysics, its Physics type could be set on#Kinematics.

You at least need to use the Physics Colliders so that the part doesn’t fall through the machine geometry. At the moment your whole machine is just one feature, which makes it complicated for the software to define the colliders correctly. It will work a lot better if you divide your geometry (with the Explode, Split or Slice tools) to get your different parts as different colliders. For example, if you want to simulate a box in Physics and parts getting in the box, you need to divide the 4 sides of the box and the bottom as different features, with all a Physics collider.

Thanks a lot for your explanation and the detailed tips. I really appreciate it.
Unfortunately, I still haven’t been able to get it working even after trying to split the geometry and set up the colliders as suggested. At this point I’m a bit unsure where exactly the issue lies or what the best next step would be.

Do you maybe have an idea where I should focus my troubleshooting, or if there’s any kind of workaround that could help in the meantime?

VC can currently only have convex physics colliders, so as Tilma said, it is really imporant to explode and split the machine into smaller features so that the physics collider is as realistic as possible.

Also as already mentioned, the machine physics type should be Kinematic, as we don’t want it to move around the world.
