michael campbell (3di) added a comment to T60587: adaptive displacement seams between dupli faces.

We have some ideas to do smarter adaptive subdivision for instances, for now the current behavior is as intended. Any improvements in this area are outside the scope of the bug tracker.

We would probably do uniform edge length subdivision for instances, possibly with a detail level based on the distance of the closest instances to the camera.

You can't use adaptive subdivision for this purpose, we don't consider that a bug.

If you have an example .blend without adaptive subdivision and with a seamless texture we can look at it. If not there is nothing to fix here.

Here's the problem, the adaptive subdivision is being carried out on the first instance only, so that the end of the first instance is low poly, but then it meets back up with the high poly end when it's repeated. Would it be possible to perform the adaptive subdivision as it currently does, but limit the adaptivity to the inner part of the mesh, so that the outmost loop of polygons all get the same number of subdivisions as whatever the highest value on the mesh is (closest to camera).

A fix would probably be to make sure a change in subdivision cant occur where two instances meet.

Hi, it's the object, mapping, and noise are identical on both left and right models. This is just an example file, the client file was using a seamless texture from poligon, and the results where the same. No matter how high the subdiv's are increased or how close the camera is, the result is still a visible seam between instances.

texture is seamless between duplicates (see right hand object which has same material minus the displacement).

Maybe, it is hard to tell. I have a lot of other bugs I need to review, could you create an example file for me?

That way at least I we know that you have issues with that file and I can see if I have them too.

Did you forget to attach a test file?

I can't reproduce this with the default cube scene at least.

Ah sorry, it was such bad logic I presumed it must be a bug. Posted in the feedback forum. Apologies.

perhaps it would be possible to have cycles to pause rendering automatically when the gpu becomes unresponsive for system tdr - 1? Maybe throw up a message asking if you'd like to swap to cpu mode, with a remember this decision for future occurances (overideable in the user preferences system tab)

Hi Brecht, you're quite right, I've just checked the system log and it was gpu timeout.
