So basically i have the same door union in 2 different places (place 1 and place 2). In place 1, the union is fine, everything works. But in place 2, if i were to insert the unions in. It looks fine, but when i test/play, some of the unions are invisible. And if i were to close and reopen studio. the union has become permanently invisible in place 2. I can still collide with the union, But can’t see the union. I also can’t preform any editing actions on the union (like trying to negate, union and separate) And if i play online. it just goes invisible. Help would be appreciated. Thanks!
Replacing the contents of this field with the working AssetID and saving the XML file will completely fix the problem, but developers don’t have easy access to CSG assets uploaded for them.
Somehow presumably the AssetID isn’t being serialized with the instance, or if changes were made to the union it’s failing to upload the CSG asset and blanking/deleting the AssetID associated with the instance.
You can refer to this tutorial I wrote today about recovering from this issue. I discovered that SolidModels exist after looking into your case, and did some more research after that.
The SolidModel I link above refers to the body of your door union iirc.
