Greetings,
While I was making a map I came across an issue - the Union I made isn’t allowing my avatar to fall through. I want to be able to fall through the hole I created, but it doesn’t want to go through.
I’ve tried toggling the CanCollide property of the NegativePart to false, but it didn’t seem to do anything. Keep in mind that the part that I am using to cut the grass with is a Union.

Any help is appreciated, thanks!
Have you tried changing the CollisionFidelity in the properties of the union to PreciseConvexDecomposition? This could possibly solve your issue that you’re having.
Oh yes, I also tried that but it didn’t seem to fix the issue. Thank you for your help, though.
If you cant fix this, dont be lazy to recreate this union by only using positive parts!
Sometimes we lose more time trying to fix something by a way so we dont lose our work, but there are simpler ways to fix it!
Unions in roblox are sometimes weird, so I recommend you to use only Normal parts.
Nice day! 
Unions usually have messed up collisions, your best fix would just be to create the hitbox with invisible parts OR try converting it into a mesh, optimize it, and set PreciseFidelityCollision on, or finally just building it with normal parts instead.
