When I tried to union 2 normal parts, this warning came out.

I tried doing DisableCSGv2 = False but it still doesn’t work.
How can I fix it?

I believe CSG Error -25 signifies a corrupt union, I’d recommend remaking the union, this only should happen rarely.

I tried remaking the union and it worked. Thank you.

When you ran into this issue, was it during a Team Create session or a solo Studio Edit session?

#5

I was buidling on a solo studio edit place. The place was private.
