I really struggle sometimes getting populations to sit on terrains and not sit underneath them. I assume the sit on terrain feature is broken at the moment but is there anyway to work around it?
In this example I've kept it really simple, I've added a terrain and then added a population of grass (internal) and told it to sit on the Computer Terrain. Thats all I've done, there's no massive displacements, no shaders at all, yet it doesn't work. You can see in the preview window how the grass appears to sit on the terrain ok but as soon as I render it I can see the grass getting drawn but then the terrain covers it. Can you see in the nodes screenshots anything I might have done wrong? Maybe the sit on terrain feature isn't broken and it's something I need to do different.
I've added the tgd file.
