I tried my testfiles that I mentioned earlier in this thread. You can get them from here: https://developer.blender.org/T51820
They come from Houdini and load fine with UVs into other applications (e. g. gaffer)

I just tried with the latest buildbot version (c66983c). It's not working for me :/

mmmhh, doesn't work for me, but probably I'm just doing it wrong. But if that's the final workflow for the Blender 2.7x branch I'd better go and try again...

+1 on the motionblur! Also an option to scale the velocity would be nice, and maybe an option to choose the channelname that provides the velocity as it might be different depending on the app that creates the alembic. Thanks!

But if the node is broken because it is incomplete? It is actually only usable if it is not animated.

Not real fan of all those "flexibility" nodes which only allows to blindly type in something, without knowing what's right and what's wrong and not having a good visualization of where issue is coming from when debugging shaders (which happens every so often in a team work).

Thomas Volkmann (knekke) added a comment to T38384: Layer Manager.

Sorry, my bad. I was mixing up layers and renderlayers... personally I find it quite confusing to have both, and I almost never used the layermanger in Softimage which doesn't mean it doesn't have any use cases.
The strength of the Softimage (and now Maya and probably others as well by now) system is, that you can have totally different settings/object-groups/overrides per renderlayer. And renderlayers are build from objects, not from layers. I think this is the most important part, because it gives you absolute freedom in organizing what you want to render.
The most common use case for this is probably the creation of additional RGB-masks for comp (which probably will be obsolete when every renderer is supporting some cryptomatte stuff).
Let's say you have a complex model and want to create a mask for some parts because you really would like to tweak it in comp. Unfortunately all these parts are on the same layer and you can't reorganize the without breaking other renderlayers. So you end up copying stuff and pollute your scene. This is how it works in Blender right now, is it? (I might be totally wrong...please correct me if I am).
In Softimage you would just generate a new renderlayer, which automatically has one Partition that contains all renderable objects. Put a constant black material on this partition, and then create partitions with a red,green and blue material. Just move the objects of your choice to one of the colorMat partitions and you have an nice RGB mask in no time without polluting your scene. (btw, partitions also exist for lights in the same manner, plus you can have totally different environment settings per renderlayer)

Hi,
I didn't read through all the comments, so it might have been mentioned before, but I just want to stress that it is really important to have some grouping functionality inside a layer (called Partitions in good old Softimage, and now Collections in the Maya ripoff). This makes it possible to have multiple override materials and properties inside a layer. Here is a screenshot that might explain how it works (otherwise ask, or google Softimage partitions).

I get a segmentation fault when I load my example .abc. It loads, but when I start scrubbing the timeline it crashes after a second or so (clicking the timeline seems to work):

So for the scope of this patch, even if it is hacky, it could work as a temporary solution to get camera streaming.

Regarding building Alembic:
Make sure to checkout a release version (git checkout 1.5.8) this will create a nice folder /usr/local/alembic-1.5.8 when you build it.
Instead of assigning all the alembic libs in cmake, you can "export ALEMBIC_ROOT_DIR=/usr/local/alembic-1.5.8" before running cmake. This way all the alembic stuff is found automatically.
All this from the top of may head, so all this might not exactly be as I stated....

Here is an Alembic archive to play around with: Alembic_Data.7z
Animated Camera with animated FoV, deforming meshes with multiple materials and a bit of hierarchy. Also there is a jpg-sequence for reference.
The original patch is handling it quite well (except for the FoV animation).

Alright, have it running now. On import both Forward and Up- axis are set do +X by default. Changing up to Z does something, but results in some crooked angle.
More tests later.

I would take a linux build for testing, I just don't have time to build it myself.
Also I can probably provide some alembic files later.

Yes, a build would help to test this.
So animation im-/export is not supported right now, but will be soon? Do I get that right?

Using it in production right now... just because I can. Wouldn't have happened without that patch.

I just managed to build it on Fedora 22 and took a quick look.
Works exactly how I would want it to work! Thanks for sharing this awesome patch DwarfLabs!!!
I really hope this get's implemented soon, as I am sure it will bring a lot of attention to Blender from people/Studios who were scared away, because they couldn't easily get their existing assets in (or stuff made in Blender out)....

Thomas Volkmann (knekke) added a comment to T43447: Config load order.

My guess is that people who are using multiple builds are:

  • powerusers who know what they are doing anyway
  • by far not as many as regular satisfied-with-the-official-build users.

It would be easy for them to skip their userfolder and only use the config that belongs to each build.
