I’m not exactly sure what I did to make the part start having this issue, but when I try to make the NegateOperation back to a normal part, I just get the “Unrecognized format” error. I can supply the part I’m talking about. Now the part will be invisible like how UnionOperation sometimes acts if broken. This is different because it is a NegateOperation.
Did you try to edit the child data at all to compress it, or did this happen on its own?
I didn’t edit any of its data. I know I did something to make it cause the behavior. I’ll pay attention next time to see if I can grab a repro.
I’ve just noticed a load of invisible UnionOperations on one of my models, it appears to be having the same issue, not allowing me to separate them. Have never seen this before the last update.
Would like to get the unions back, but I doubt that’s possible now. Possibly corrupted whilst saving? This also appears to be an issue in-game, therefore should probably be moved to client bugs.
EDIT: It appears that only UnionOperations named “Union” have been affected. All others are fine and dandy.
Whenever I accidentally negate a CSG union, and try to un-negate by clicking negate again, studio crashes.
