Hello everyone,
I’m running into a frustrating issue with Physics Constraints in Unreal Engine 5.8.1.
My Setup:
- I’m building a block-building system similar to Minecraft, using physics-based construction.
- When the player presses a button, a line trace determines the spawn location, and a BP_BuildingBlock actor is spawned there.
- After spawning, the new block performs a line trace in all 6 directions to find neighboring blocks and attaches itself to them using a Physics Constraint component.
- All constraints are set to “Locked” mode for both Linear and Angular limits to achieve rigid connections.
The Problem: Despite all settings being set to “Locked”, the connections behave like rubber bands or springs.
The issue is especially noticeable in long chains of blocks.
Thank you in advance!
