A few weeks ago, Lathan added a block trigger system which will be used for the restore power quest. Multiple triggers, like switches, can be on a layer and blocks, like doors, can respond to them by doing something such as opening or closing.
It is in 3d. They can see in the direction their head is and hear all around. Feral Sense just makes the falloff with distance lower, so they see and hear farther.
Sleeper volumes don't even spawn zombies until you are near them, then those zombies are passive (can't see or hear) until you are at the edge of the volume, then feral sense matters.
Crops have no changes I'm aware of.
Well now it looks a bit better and is tied into draw distance to add more planes when set to the higher distances. Our artists definitely what to make better art for all plants, but that is more like A21.
A big part of it was separating the collision mesh from the visual mesh as this change describes:
"Optimized grass collider generation (Always 2 centered, fixed size and axis aligned planes)."
More complicated grass meshes do not need a more complicated collision mesh and their collision meshes should not stray into adjacent blocks like they did.
It does that too for the mesh. On the higher grass distances, you don't have 2 planes in a + pattern. It is 3 is an overlapping triangle.
And this: "Increased grass mesh variations to 192 (image, scale, rotation, cross/ring)."
That is generally true, but not all the time. At 4k on a RTX 2070 with higher video settings I become GPU bound, so end up turning some video settings down. DLSS would potentially save some GPU, giving a higher FPS without having to turn down some settings.
Unity games don't make their own render pipeline. You use the built in one or one of the new scriptable ones. The scriptable ones let you make a ton of changes, but Unity is still doing the heavy lifting. Unity is still what talks to the graphics API (DX, OpenGL, Metal, Vulkan).
Not in A20.
I think we all like it. Not sure why anyone would not. I think it is top secret at this point, so if I showed you, I would have to....
