Please come share your thoughts on this new game type and level set.

Looking for feedback on a level pack and game mode nearing release.

Transparent water? Falling snowflakes? Plus a few others.

I'm working with a few rocks from the lumberyard release and all of them are walk through. Can i solidify them so i can use them to walk/stand on?

I want to do a few things with intel: drops on contact with water / beacons the player and want to make an entity that points at the player with the intel (currently using a beam)

Every time I hollow a sphere, whether inverted or not, a few shapes bug out.

I'm curious if could be possible to have a point capture alter a select texture to change it in game.

I'm curious what exactly i need to do to get Portal models and textures into Hammer for use when making a Team Fortress 2 Map.
