Negate and Union Lag

I’m trying to use negate and union for a build I’m making, but every time I try to use union, my Roblox studio becomes really laggy and doesn’t respond. Sometimes, it even crashes.

I thought it was because I was using too many parts at once, so I reduced the amount of parts I was unioning. However, my Roblox studio still lagged.

Using union takes hours for me; one time, I let it union for 4 hours and it still didn’t work. Could someone please tell me what I could do to stop union from causing Roblox studio to lag/crash? Anything helps!

Rule to be learned: unions suck.

Roblox uses CSG to create calculations in unions, which creates unneeded vertices and triangles.
Generally, I recommend using Blender for models.

Thank you so much! But how I could create indents like you’d see in a pillar using blender?

Would I need to select the sections I want to indent then pull them inwards? Or is there a better way to do this?

This is what I mean by pillar indents.

You can use Ctrl+R to create loop cuts.

No, unions are very good and useful.

Unions create unnecessary vertices and faces, causing significant lag.
Make a union and import it into blender, see what happens.

unions have a chance to corrupt.

Both are good. Depends on how you use it.
