Adam Janz (Copperplate) added a comment to T50565: Transform: Planar constraints don't work properly with non-Blender key configurations.

I encountered this issue with my own Blender key config. In fact, both of the Shift-Left Mouse commands for view3d.manipulator were somehow missing, although I don't recall deleting them. I added them both of them back in manually to my key config, exactly as in Blender's default config, but they still don't work. They only work in Blender default. I'd really like to be able to use this feature with my custom config as I have some very handy shortcuts I use frequently, namely:

Adam Janz (Copperplate) added a comment to T52656: Driver stops updating dynamically if no/incomplete variable is defined.

Whew... I was finally able to wake it up in the most bizarre way! If the driver is in this frozen state, you MUST add a variable that references an OBJECT ID Block and add some animation to the object, then set the driver variable type to "Transform Channel". Trying to use an animated single property (such as evaluation time on a Path) will NOT work. Of course, this placeholder variable does not need to be used in your scripted expression, it simply sits there to prevent the driver's door from locking! :-)

Adam Janz (Copperplate) added a comment to T52656: Driver stops updating dynamically if no/incomplete variable is defined.

Wow... this is insane. Even though I was able to successfully wake up the driver by adding a variable in a new project, in the original project that glitched, it has remained frozen. Still investigating why this bug is occurring. I tried the f76d49e latest build along with the 8928d9270f official 2.79a build and neither can wake up the drivers! The glitch had occurred in the earlier d640ce4 build.

I couldn't figure out why Blender drivers suddenly stopped working without explanation even with Auto Run Python Scripts checked. But I thank God for showing me it was because a no-longer-needed variable had been deleted. Well, now I know that Blender requires at least one variable to be present even if not being referenced for drivers to execute. :-) There definitely should be a default warning of "Must set at least 1 variable for driver to execute" when adding a scripted expression and no variable has been set.

Adam Janz (Copperplate) closed T54177: Impossible to Unlink Material Animation Data? as Invalid.

Praise God for showing me the solution! In the outliner, type "Animation", then right click on the object's animation data you want to remove and click "Clear Animation Data"; or just hit Spacebar and type "Clear Animation". It's too bad there's no interactive context for clearing this as we have with Actions, however, it's great that a simple solution is available. :-)

Adam Janz (Copperplate) added a comment to T54177: Impossible to Unlink Material Animation Data?.

Ugh... the same thing is true for Curve path animation data (evaluation time). Duplicating a portion of a curve that has an animated eval time so you can modify the trajectory at a specific point without affecting the original path is currently impossible due to both paths incorrectly sharing the same data block. Does anyone know of a workaround for either issue? Surely materials and curves cannot always be animated as a final step after all duplication is done, otherwise that would hinder the creative workflow tremendously.

Hey Brecht, this is a phenomenal feature that has shaved off over a minute-and-a-half per frame of render time using the d640ce4 build. Are we able to get this feature in 2.79a? It's not present in the current release candidate, but this is such an incredibly useful feature for animations, saving literally hours of render time.

Wow, wow, wow!!! I cannot thank you guys enough! I just tried the new Blender 2.79 d640ce4 build, and it is FLAWLESS. All 68 material previews load nearly instantly... it's as if I'm running a new super computer! Not only that, but the small previews now accurately reflect the larger previews without sacrificing anything. It's incredible!

Sounds good; I didn't even realize the icons were using the world texture, but I just checked and sure enough, the icons for the chrome-like materials don't even represent their larger material previews at all (since my scene texture is tinted). So basically, either the solid color method or, if possible, just use the same preview image as in the larger material preview (with the gray checkered background for reflections). This would also help with visual consistency.

Thanks Damien for helping out with testing this situation. I have one 5000 x 2500 .jpg image and one 5000 x 2500 .hdr image in the scene. These 2 textures represent only 2 of the 68 materials. A portion of the other materials use multiple 2K textures. So it would seem then, that even 2K textures cause Blender to slow to a crawl, as it is calculating the tiny previews at full resolution. If there was a way to calculate at lower resolution (as Damien mentioned) or to somehow locally save the tiny preview after it's calculated once so it will not constantly go offline would be great.

Sorry I haven't been able to test with factory settings at present, as I'm in the middle of working on a project; however, here is the system info file. I have about 68 materials in this project, and I add a new cube, click the "Browse Material" button to select a material I already have, and Blender will choke to a crawl for about 2 minutes as the 68 previews build.

I can confirm this is still happening. Blender freezes when the material dropdown is opened, and the memory usage continues to climb long after the drop down is closed. Very unusual behavior. Triple buffer does nothing to remedy it.

Adam Janz (Copperplate) added a comment to T45854: Hold forward is reseted in NLA.

Thanks Philipp. Is there any chance this bug could be fixed by one of the devs within the next few days? It is really slowing down the animation of a project which I need to submit by the 11th. It basically doesn't allow the Non-Linear Action editor to be used in a Non-Linear manner, as any update to the strips will destroy the settings in all the other ones. This forces you to have all strips start at frame 1, even if the action doesn't occur until frame 100 (essentially a Linear editing workflow).

This bug would explain why I would sometimes experience weird glitchy behavior in an animation project back in 2015. Now that I have discovered it was all due to the NLA strips switching to "Hold Forward", I will have to be extremely cautious every time a change is made in this new project, unless someone has found a workaround.

No problem, thank you Brent and Sergey for your clarification. I ran into this issue initially creating large environment assets for use in UE4. The scene unit scale has to be set to 0.01 to convert to centimeters in UE4 (at least it used to, not sure if it's still required). I had my clipping distance set to 1 KM to accommodate a very large mesh, so I initially couldn't figure out why the sculpt tool wasn't working. :-) Thanks for the helpful troubleshooting link. Have a great day, guys.

Thanks Joshua and Brendon for your input. I did notice that manually setting visual LocRotScale keyframes and then hitting Bake Action produced much more accurate (but not perfect) results than just hitting Ctrl Alt C to clear the contraints. Maybe because the visual keying gets applied twice?

Adam Janz (Copperplate) added a comment to T52063: Bake Action inaccurate for Spline IK.

I can confirm there is still a very slight discrepancy (basically negligible) at times even when manually setting visual LocRotScale keyframes and then clearing all constraints manually using Ctrl Alt C. This is likely the nature of Blender not being able to truly pinpoint the position of bones affected by the Spline IK constraint after visually keying. However, there is no doubt something wrong with the way Bake Action does the visual keying on Spline IK affected bones, as 9/10 times there is a fairly large discrepancy.

Adam Janz (Copperplate) added a comment to T51683: Renaming numbered bones in Outliner does not re-order them alphabetically.

Thanks, Bastien, for letting me know. I guess that would make this a feature request, then. :-) It would be great if the outliner could replicate the behavior of renaming vertex groups, except with bones. There's lots of sort options available there: you can automatically re-order alphabetically if you have "sort items by their name" checked, or, if unchecked, you can click "Sort by Name" in the vertex group specials as a 2nd step and it will update. I could see this being an extremely useful feature, as some custom-non-character rigs require many numbered bones, and in my case, the bone numbering needed to be swapped, which completely messed up the outliner. For this particular rig, I relied heavily on the outliner for bone selection and once I fixed the ordering problem, it made it a lot easier.

I had to trick it by separating all the bones into their own individual armatures then re-combining them one by one back into the original armature. This worked good since I had only 6 bones affected, however, it would be quite tedious if a large number of bones had to be renamed.

Yep, that's what it was: "Prefer Maximum Performance"! That was the only setting I changed just now, and sure enough, no more stuttering. So I guess the new "power saving" modes must have been added in the newer drivers and that's what broke it. Basically then, when I enabled the screen capture settings in my previous workaround, the GPU must have kicked into the "Prefer Maximum Performance" mode, which "indirectly" solved the stuttering.

Thanks so much, Daniel! Yes, that does work, however, I noticed the settings only take effect once Blender is closed and re-opened (I tried changing the settings one at a time with Blender open to no effect). And resetting NVIDIA control panel back to default does cause Blender to re-exhibit the issue (when closed and re-opened). I'd have to try those 5 different settings individually while opening and closing Blender each time to know which of those settings are directly affecting the issue.
