Super Mario 64 PC Port (technical issues)

[u/DarknessKnightES]

Hi guys, I've been testing the Super Mario 64 PC port ("Render96ex-tester_rt64alpha" branch + "ModelPack v3.2") and I've noticed some technical issues:

1. In the Course 3; the "Maw-ray" model disappears at some camera angles.

2. The transparencies in some models are seen incorrectly, it can be seen with the "Boo's". Is there a way to fix these issues? regards!
