Thanks very much for the video, this clearly shows (to me, anyway) something different to the known instancing problem. This is more like a shimmering effect, which seems to be where the blended (not completely solid nor completely transparent) parts of the trees are constantly changing how they're rendered. It may be worth noting here that we split blended primitives in to two parts, one for any solid areas and one for any blended areas.
I'm not sure I've seen this before, but I can probably explain what's going on/wrong. Solid primitives are rendered using a depth buffer which means rendering order is unimportant (this is a good optimisation, all games use it), but for blended/translucent primitives they must be rendered in depth order (as the depth buffer cannot help). We (OR) do sort blended primitives before rendering them, but - possibly due to the density/closeness of the trees - in this case we're not doing a very good job and each frame subsequently renders them in a different order. Because by their very nature they blend with what's behind, alternating the order will cause a flickering effect.

I will state once again what I love about OR--the people developing and enhancing the program actually listen to their users. Thank you, OR Development Team!!!!

Waaaaay :offtopic: ---- IMHO, that's why humans are always feudin', fussin', and fightin' each other all the time!!
[ also, :sign_thanks: James, for the explanation, and railguy for the description of the flashing phenom)

And I thought you were truing to show low and high tides on the Bay. The flashing water ocurred in an earlier version of OR, but not now. Sill getting what I call a "shimmering" of the foliage. As though the wind was blowing at 40 (like it usually does on the bay).
BTW. Love the route and have spent much time in that part of NS. Only real change in the area (aside from the DAR closing) is the gypsum mine is closed, there is virtually no trackage left in Kentville and there over 15 new vineyards and wineries in the valley.
