Back in 1.2.5 when I used this mod with my same graphics card I could see through the portals, but now in 1.4.7 I'm unable to. I've made sure that everything is installed properly, and tried using an instance of MultiMC with only the Portal Gun mod and Forge to check for any conflicts. My drivers are up-to-date as well. What exactly happens is that instead of showing what's on the other side of the portal, I just see the color of the sky. Nothing else seems to be wrong with the mod. Any ideas as to what the problem is and how to fix it?
