OK, it's been a month since I originally asked this. I'd still like a response. As it stands, I can no longer use SMP for certain things that it used to work on. If this is something that isn't going to be fixed for whatever reason, I need to know so I can find another solution. I'm having a problem with the swimming pack when using volumes to define swimming areas. I remember this being an issue years ago, which was fixed, but now it seems to be doing it again. I was trying to use a box collider to define a swimmable volume, and couldn't get the player to rise to the surface. It seems that the "surface" is now set by the pivot point of the collider, instead of the upper surface plane of the box. Also, the player no longer knows when he's left the collider. Here's a comparison of Motion Controller 2.75, using SMP 0.63 vs 2.806 / 0.65. I used Unity 2018.2.5 for both tests, to eliminate any Unity upgrade issues between versions, but also confirmed this behavior on MC 2.804 / SMP 0.64 in Unity 2019.4.5. I couldn't try MC 2.75 in Unity 2019 since I no longer have an installer (and I'm not sure 2.75 would run without other issues in 2019 anyway). Any ideas? Is this a code regression, or do I need to set this up differently now?
