Problems with Union Hitboxes

Hello!
I have been having problems with the union I am going to attach onto here, I’ve done everything past Devforum posts have suggested to attempt, and it hasn’t helped me. When I try and stand on the invisible negated areas, it doesn’t let me go through them like it should. Instead, it registers as part of the main hitbox and causes me to not fall through. I’ve currently attempted reunioning the parts, changing the Render/Collision Fidelity, and reorganizing the unioned parts. If I could get some help with this I’d appreciate it very much, thanks!

Roblox has had problems with union hitboxes since it probably came out, but as you know they are too negligent to make changes!

Yes, i do. I believe we’re up to v3 of the CSG engine? I remember it coming out in 2020 or 2021 and there’s still issues with it to this day.

I think it might work if you change the CollisionFidelity to PreciseConvex.

Unfortunately, I already tried that and it didn’t work :confused:

Your best bet is to separate the union, or remove collision from it and recreate the collision with invisible parts.

This is what i ended up doing. Thanks and sorry for the late reply, I came to this conclusion on my own.
