There are compatibility issues. The 2.79 build has additional features and changes to settings. You can't go back to 2.79b if you use the daily build.

The daily build is a zip file without any installation, it can be put anywhere without affecting other Blender versions.

Doh, ok thanks. When will the last daily be available from the official download link rather than the experimental 'do not use in production' link? Really want those updates, but my client won't update their farm with anything but the official release.

Thanks Brecht, are there any backwards compatibility issues with the 2.79b daily builds and the 2.79b official release? I'll probably update if there aren't any issues (just being careful because my client won't upgrade until the daily build replaces the official build)

michael campbell (3di) added a comment to T64520: edit mode crosshair too small to see on 4k monitor..

display scaling is 150% on the 4k monitor and 100% on the 1080p display. Changing to 100% on the 4k display still shows the dot version of the crosshair instead of the solid white lines crosshair.

Hi Christopher, it's a little better, but I think the problem is the crosshair style. The dots which make the cursor up are still barely visible, particularly when there's a lot of geometry. Just to clarify, if I drag blender over to my 1080p monitor, then the cursor returns to being a solid white crosshair and is easily visible, but on the 4k screen, it turns to the barely visible crosshair which is made of 8 small dots rather than being solid lines.

Hi Marco, screencast replaces the crosshair shown in blender with a much thicker solid white crosshair which is easy to see. In blender the crosshair appears as 4 small outer dots (one at each end of the cross), and 4 small dots in the centre of the crosshair. The outer dots are approximately 2 pixels wide, and the centre dots are approximately 1 pixel wide, which as I'm sure you can images is very difficult to see on a 4k screen.

Hi Marco, you can't screens shot a mouse pointer. I'd love to try the latest build, but unfortunately we're not allowed to use anything but the official build. Is there any chance you guys could update the official download so that it's the latest stable daily?

Hi Brecht, we're not allowed to use daily builds. Any ETA on when the main download link will be updated to a more recent version that may contain relevant bug fixes?

michael campbell (3di) added a comment to T63714: physics calculation speed very slow in scenes with lots of scattered objects on non visible layers.

Thanks Brecht, that's great news, as this is crippling workflow at the moment. Perhaps an option to only calculate selected objects during anim player playback would also be beneficial (making live playback as fast as manual scrubbing( dependant on what's selected))......and an instance array modifier for arrays that don't need to be deformed or result in one merged object....requested here:

one thing that might be a bug though (can't imagine it's by design)....when things are hidden, either by having the layer switched off, or the object not visible, is there any point in it's modifiers being calculated during anim player playback?

michael campbell (3di) closed T63714: physics calculation speed very slow in scenes with lots of scattered objects on non visible layers as Invalid.

Scrap that, after searching the scene item by item (I didn't create the file), I found that there was one object nestled amongst several hundred that had an array modifier on it! Resolved the playback speed by replacing the array with dupli groups.....I pray for the day that we can have an instance array modifier like we have in Houdini.

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.

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

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.

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

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).

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

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

Hi, 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.

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.
