I thought ResizeMe was the best VR experience until I discovered Virt-a-mate
Big learning curve to understand on how to load community created scenes. Plus I believe you need be part of the $2 per month patreon tier in order to edit scenes to your liking. Some custom scenes, I like to edit the models shape and clothes to my liking.
https://directory.vamresources.com is where you find free and paid community created scenes. Use the filters and select "size". Anything by LowTerm9 is the best for POV slow shrinking scenes. Highly recommend Tall Wife. Again, not a fan of the models and clothes, but that can always be edited.
Unfortunately I won't be the best to instruct others how to use it. Best to use the resources found on their sub-reddit which includes all the tutorials.
