I’m trying and trying and no matter what I do, I can’t seem to get this to work. This is what happens all the time(should this be an expected result?):
True displacement is as experimental as you can get in Blender…
It is nowhere near production ready and any kind of erratic behaviour is indeed to be expected. The only reliable way of getting displacement in Blender still is the Displace modifier.
Ahhh, I was afraid of that… Thanks for the explanation and I’m hoping they put opensubdiv into blender as soon as possible, because it’s much needed for optimized rendering. Thanks again!
Sorry, but I tried your file on two different machines and Blender crashes immediately when activating the rendered viewport or hitting F12. That’s not exactly what I call “reliable”…
BTW, I never said that it does not work. I just said that it is unfinished and buggy and I fully stand to that statement.
Wait, isn’t the point of true displacement that it subdivides the mesh itself? I don’t see the point in using a subdivision modifier if there’s a dicing rate option in object data? Ultimately it should of course tessellate the mesh dinamically. Thank you for your replies, guys

no
“true” displacement works. the dicing option has nothing to do with displacement…
these are 2 things:
dicing is for the geometry you could use that without displacement its just another way of subdividing your mesh (this is not working at the moment don’t use it)
the true displacement function (which works - if not make a bug report) is for deforming the geometry. It doesn’t matter where the geometry comes from…
Then I will file a bug report for dicing. Without the dicing option it is the same as subdividing the mesh using the subdivide modifier and then displacing the mesh using the displace modifier. The point of this is for it to subdivide the mesh when you start rendering or previewing. If I’m going to subdivide the mesh using the subdivide modifier it’s already taking up loads of RAM. And no, the Simplify option doesn’t help, because there is no setting for Viewport. If I set the subdivision level low to be able to use the viewport normally, the preview render also has the same low subdivision level. The whole point - as I see it - of this setting is the dicing option. Otherwise I might as well use the displace modifier.
