How to remove a sphere of land out of a large union

Help and Feedback Building Support
#1

I have been trying for the past 6 hours to use the negate and union thing to create a gap in a union, to create room for a pond, however every time I do it, the union gets messed up, and the sphere shape greatly deforms unexpectantly.

Any way to avoid this?

Would like visuals or a video that explains and shows the problem, I think that would help explain the problem a lot. If you can’t do that, try reducing the amount of times you have unioned the union or reduce the amount of parts used in the union.

I made it large as I have to have it large for my project.

As you can see, everyone time I negate → union it, it creates a different deformation in it, varying in chaoticness

#4

I understand now, so you can solve this two ways:

  1. Make the parts smaller, then union/negate them, then resize them up as you like
  2. Instead of using negates and unions, use a ton of parts to make a pond

If that does not solve your issue then I have no other clue. Hope this helps.

I don’t know but it could just be the lighting. Try changing the lighting around a bit or turning off Castshadow to see if it looks any better.

It unfortunately is not the lighting. When I merge them it creates all the odd shapes still, and they are very solid

In regards to the first 1, I have tried making it smaller, but it still has the small flaws in it. Also, the total size of the part needs to be larger than the maximum it can be set as (its size is like (3000,100,3000), and if I change the size downwards the maximum it can go back to is (2048,1000,2048) sadly

In regards to the 2nd one, Ill give that a try I guess, shame that it can’t be done easily but Roblox isn’t perfect ;/

I never seen an issue like this before. You can definitely take @Azul_Cult’s advice, however I have some alternative solutions for your consideration.

You can ask a friend to make this part for you.

Since this seems like a Studio bug, you can also see if uninstalling and reinstalling Roblox Studio may fix the problem for you
