Ground cover billboarding


Recommended Posts

If I'm correct, the imposters (auto billboard) don't work for 3d shapes as groundcover objects. (I should check, but no time) Think it only works for shapes where the onload() function is called; which isn't the case for groundcover.

Thought there's a possibility to add a plane mesh to your shape as LOD and use the old BB:: technique to define it as a billboard for export to DTS. But that one as pretty old; little documentation and comes with default with axis issues (if you don't know how it works).

We added a plane mesh as the lowest LOD and used the same texture to avoid an extra draw call. It works pretty well if you have a lot of objects like grass and so on:

And a second option; is to create 2 groundcover objects in your scene; 1 with billboards (default groundcover setting) and a second with 3d shapes. Play around with the distances and don't show the billboards until the far distance of the 3d shapes. Hope it makes sense what I've just written :lol:
