Rotation motion blur- object shrink problem

[doca]

I have a problem with motion blur with rotations. I was exporting alembic from Softimage with all possible settings (both with default alembic exporter and Exocortex exporter), but no luck. Objects are shrinking, doesn't matter what settings I choose. Then I tried to export same animation from 3dsMax (again with default alembic exporter and Exocortex), but no luck too. There is definitely a problem with rotations, I tried alembic with other render engines and everything is fine. Here are some screenshots:

same here
I even can't find the motionblur section in standalone(latest 3.02), I also test with 3ds max export as abc files, I need the car body with no motionblur and the rest including wheels have proper motionblur and camera blur, in standalone I don't know where I can adjust this, could someone please guide me through
oh btw, in 3ds max it rendered very well

Hi,
in v3, all the motion blur settings are collected now in the new pin Animation node inside each Render Target node.
https://docs.otoy.com/manuals/products/ ... tion-blur/

In general, only with integrated plugin you have the ability to specify different motion blur behavior based on single objects, while standalone need to find this informations in the alembic node.

Everything is clear about that Beppe, but that is not the answer to the problem. And the problem is how to solve this strange (shrinking) behavior in standalone? There is definitely something wrong with motion blur in standalone. If this is the limit or a bug in standalone, I/we want to know that. Not to waste good amount of time asking myself what I did wrong.
So, how to solve this? If this is a bug or bad code or whatever, will it be solved? When?

Sorry doca,
I have tried to reproduce your issue exporting from c4d, but without success.
Could you share an example alembic file with us?

Sure, here are the files. There is abc camera and abc geometry in the rar file. Go to the frame 1010 and check motion blur. Just to say if I was not clear, I am on Standalone Octane.

Hi Doca,
what are your animation settings?
I cannot find a value that gives asymmetrical result like in your previous post

Here are some screenshot with different settings. But whatever value I put result is incorrect. Do you have correct result? If so, please, tell me what settings to use. In my examples, symetric settings (last image), gives correct MB but shrinking is the problem.

No motion blur:

Have you already tried Increasing the object's MB samples in its object properties?

Sorry, but how to do that in Standalone?
