LOD crossfade problem

Unity Engine
1

using speedtree demo trees. crossfade set up and enabled in HDRP asset. does not crossfade at all.

also, cannot get billboards to render. they only show up on the little sphere material previews.

instead of going to billboard, it dissolves. (fades?)

anyone seen this

evidently the problem was using the “speed tree” setting with… speed trees (even with cross fade ticked).

switching to cross fade mode seems to resolve the problem.

still no billboards yet…
