This more complicated than it needs to be, there is no need for UV hashing if we are going to compare them directly.

This patch appears to be against an old version of the code, please update it to latest master.
@Sybren A. Stüvel (sybren), could you look into this? I have neither the Blender sources nor my Alembic files on my computer at the moment. Overall, apart from some style issues it looks good to me.

OKi, closing then
You can close this, I contacted SideFX, its a bug in the Houdini exporter and not Blender. Apologies for any time wasted

Hm, seems I cant reproduce (a crash).
[Same for 2.79 master and 2.79b btw.]
@Sybren A. Stüvel (sybren) : mind having a look?
I have attached a simplified .abc that is still able to reproduce the crash.
Please try to reproduce with something you can share publicly.
(there might be multiple people involved in such a report and exchanging assets between all those persons via mail is just not practical).

We are seeing a couple of issues here (possibly we'll be splitting these in distinct reports if neccessary):
Attached is a scene from 3ds max with no animation exported as Alembic. Blender 2.8 crashes when I import this.
Oct 26 2018
we need the updated .abc as well...
I have done a lower resolution test with the same track animation for the camera.
Interestingly, the camera is not animated in the ABC file.. That being said, it no longer crashed. Files attached
@Jesse (FreakTheMighty) : cant reproduce.
in 2.79, the provided FBX wont import Focal Length [but that is expected since rBAb890f0d7e8a6 isnt included]
in 2.79b (or onwards), the provided FBX will import Focal Length [bunch of keyframes, but all very similar -- around 8.1/8.2mm]
crashes in 2.79 as well

There seems to be a curve in the .abc as well (Circle.001)?
let me know if you have any issues downloading
Cannot reproduce (when exporting from blender itself)

Not sure why, but focal length keying worked for me in Blender Version 2.79 (2.79 2017-09-11, Blender Foundation), but does not work in Version 2.79b (2.79b 2018-03-22, Blender Foundation).

Confirmed the vertex can be read correctly by Blender and two other softwares, and Alembic regression tests are passing.
Confirmed. @Sergey Sharybin (sergey), am going to summon you here, since I believe there may be something wrong in DEG - animation is in the CacheFile datablock, hence not in Object one (as any other modifier would be). And it is never evaluated afaict, even though dependency looks correct?
Thanks dude! I hope I have time to test & commit this soon :)

I went ahead and took the plunge into the Blender source and sure enough I fixed it! I submitted a patch at https://developer.blender.org/D3704 along with some more info on indexed writing.
I attached an Alembic file that contains a tree model with several vertex color layers. I tested it extensively in Houdini. Please test it and post back your success or failure. I hope it fixes this bug for at least Houdini and Maya.

@Sybren A. Stüvel (sybren) that one is for you I think?

Please follow our submission template and guidelines, also read these tips about bug reports, and make a complete, valid bug report, with required info, precise description of the issue (only ONE issue per report!), precise steps to reproduce it, small and simple .blend and/or other files to do so if needed, etc.

ok. you are the coder.
That’s the last time I say it: THIS BUGTRACKER IS NOT A USER SUPPORT SERVICE!
