VRChat has a model rating system that rates them based on a multitude of factors, telling you in detail each one of them and how close, or far you are from hitting each of those limits, and if you hit the limit on too many of them the model will be blocked for everyone, forcing you to optimize your model.
It would be interesting to see a system like this implemented in S&Box although more lenient, for the sake of giving 3D designers a pointer on how an ideal model would be in terms of optimization, and to allow for better optimized content posted in the Workshop (or wherever website Facepunch decides to host the workshop in). In Garry’s Mod there is no system like this, but it works because of the limits of the engine, since the compiler has a hard limit on how many vertices you can have in a model (Around 30.000 or so). But since this is a modern engine, the limit must be way higher, so heavily unoptimized models can be imported into the game, impacting weaker machines. That’s why i see a system like this being important in S&Box for the sake of having quality control.
While this doesn’t mean the Workshop won’t be filled with unoptimized models since some may just ignore it completely, it’s a step in the right direction and it will help 3D designers (like me) have a clear bar of quality to aim for.
