So, I don't mean to be a douchebag or condescending and I should preface this by saying that I'm just coming after working 20+ hours on a shader + script combo only to find out VRC has no support for custom scripts. I also know that people using shaders to crash other's clients is a commonly seen thing, so I figured, "Why haven't they hired a security expert yet?" Here is how I see this working: People upload an avatar to the server, the server builds and runs their avatar and runs through every animation to make sure none of the scripts or shaders interact with the environment in a negative way, such as crashing clients, or custom scripts modifying components outside of the user's own avatar. Limit people to uploading 1 avatar per hour or per day to save on server space, VRChat plus members get to do it more often. Now, I'm no security expert, but I reckon even I could set up such a system with some time and money. I'm not suggesting you hire me, though, because I'm almost certain there's a thousand better folks out there you could hire who are experts on this sort of thing. Please, basic scripts would be so nice to have, and this would make so much more possible for VRChat.
