So its been a little over a year since I worked with UE and I forget some of the details on source builds.
I downloaded the source, built it in VS2017, and am able to run the editor from the win64 editor build. The problem is, when I try to add VaRest to the new project via the editor Vault. It says it has already been added to all compatible projects. It shows my project list as OTHER instead of 4.20, etc. Do we have to manually add plug ins to the source build projects? Or is it possible VaRest isn’t ready for 4.20.3?
