I have seen some of that. It seems blocks can shift their position in RT mode. It may look like it is not being rendered, but I usually find the block somewhere else in the scene?

I have it logged as a problem.

A while ago, blocks with displacement (or indeed any displacement object) wouldn’t update in the scene for RT, and you had to rotate them by 360 degrees to force a position update. But I think that was fixed.

This was reported already in Rendering issue in r9 .

I closed this topic, further discussion in the linked one.
