Blender Fake Arms Animating Question

Hey, currently trying to set up some fake arms for a FPS game I’m working on.
I’m relatively new to blender animating so maybe this is a beginner mistake?

Got the arms rigged and all, but the problem is how it looks when I try to move it. Need it to look more natural.
Here’s what it looks like when I try to bend the arm:

Here’s the topology:

(Spikey thing is part of the rig, ignore it)

If anyone knows how to solve this, please feel free to share your ideas.

Thanks for reading.

Your IK seems to be set up properly with it’s Pole Target - however until the skinned mesh feature is released, you won’t be able to export this armature to Roblox anyways.

As for your solution, here’s a visual of how to go about correcting your topology for most joints:

Granted, I also think the distortions are coming from you connecting your bone to your mesh in a weird way (you can see that the upper arm’s connecting point at the elbow doesn’t move its faces), but I don’t know enough about armatures to comment on that.

Thanks for the suggestion!

Kind of fixed it with editing the weight map.
I’ll try this out to see if it works smoother in a bit.
