So I’m currently working on an elevator installation project for my test tower game. Yesterday was all fine and dandy, and I hop off and go to bed. I come back on this morning, boot up my PC as usual, and open Studio. Installs an update, nothing unusual. I open my place, and I resume work. I get to work on a beveled panel using Unions, and I try and separate it. Nothing happens except that my union gets deselected.
Okay… odd.
I try again.
Union deselects again.
I try once more.
Same thing!
I try every other Union operation on this instance. I get a CSG error code -15!
I insert a new Part and use my Part Beveler plugin to bevel the part. Once I finish & attempt to union it, I get the same error! It seems like I cannot even union any parts anymore.
It appears the leading cause of this issue is unioning with Spheres with a small scale.
Reproduction Steps:
- Insert two Parts, one a regular sized Block and another a small Cylinder (size <0.01) (or use the Part Beveler plugin, which generates a series of small cylinders & spheres to generate the “beveled” part result.)
- Select both parts, and click Union or Negate
Expected behaviour:
Unions should work just fine here. Self-explanatory. Instead I am getting Error Code -15, and I even tried looking this up everywhere. No result. This error is unknown.
