While using the latest version of probuilder 6.0.2, there is an issue with the PolyShape Tool. If you use the tool while in TopDown perspective it will create a ghost object or an object that cannot be selected from the Hierarchy. Although the PolyShape tools says “Press enter or space to finalize” this only deactivates the editor window and create the ghost object. I have not found a way to re-select the object from the editor window.
When creating a PolyShape in side view or normal free look the tool works as expected.
I’ve attempted this multiple times in new projects and received the same results.
