We have grid-snapping on our *Beta version, and it will be released launched within the next week or two. You can access our Beta if you have MasterpieceVR on Steam. You right click on MasterpieceVR in your Steam library, go to Properties > Betas > and choose Beta from the dropdown list.
Please note that the *Beta is more unstable and has a few features being tested. We’re always happy to hear feedback on features added to our Beta so you can join our Beta testers mailing list to find out how to help us test new features. Beta Testers: http://eepurl.com/c4viAP
