Unity Terrain Tools Issue - Grass Terrain Details has issues if BillBoard is turned off

Update: Tested with Racush heavily with this issue. Issue seems to be most connected with using Unity’s “Unity Terrain Tools”.

So its most closely connected that it handles Terrain Data differently from just normal Unity usage. But it is an important tool package to use for even just Terrain Splatmaps and Layer handling (aka masking for terrain textures). Also does handle Terrain splitting, so one big terrain chunk can be split into multiple smaller terrains chunks with inherited layer/details settings.

Using same terrain data and sample settings on terrain upload. But without using the aforementioned Terrain Tools makes issue non-existant.

Original Post:

Unity Terrain Grass appears to be disabled for some strange reason when using Grass Texture with Billboard option disabled.

Will still render fine in both Editor

and Mock HMD SPS-I Play mode

Relevant setting is this under the Grass Texture Option

Re-uploaded world with the Billboard option re-enabled and grass appears again to be working.
