Unable to import .alembic file in Keyshot. What to do?
« on: June 15, 2019, 12:24:08 am »

And yes while installing keyshot I selected for "Only Me" not for "Anyone on this computer"

For everyone who isn't allowed to install "only for me", can use KeyShot 7 to import the alembic file, save the bip and work on it in KeyShot 8. That is an improved solution!
Hopefully we get an update without this bug.

Cheers
Marco

No, until you asked for. I am no Blender user and I wasn't capable to export the alembic file right. Might be the turn for the Blender experts.
I can export it as fbx and can import the mesh in KeyShot 7 and 8.

Sorry - I out!

But I wish you good luck!


Cheers

You need to check the "Curves as Mesh" check box during the alembic export in Blender. Your current alembic file contains just the bezier curve without geometry/thickness. KS cannot read that.

Thank you Eugen.
I‘ve tried that, but without success. I’ve started learning Blender today.

OK - here we go.
I added a solidify modifier to the curve and exported it as the attached alembic file. Maybe I added to many options? - But finally KeyShot 7 and 8 (for all installation) was capable to import the mesh.

There are different ways to get thickness on curves. 1st is to use the solidify modifier, 2nd is to use the depth parameter in curves properties. So, there is no right or wrong. You can even use both and create a pipe ;)

P.S.: You're entering the rabbit hole my friend and you'll have a lot of fun in this new world ;D @Marco.

Did you scroll through the timeline - I have no issues with the import.

Hello (from the rabbit hole).


Are there issue with the nodes in Blender? If I open the original blend file - hm - see it in the attached screenshot.

Otherwise an animation can be transferred to KeyShot with the "deforming mesh" option within the import dialog!

You're diving too deep for a beginner Marco. ;D
The issue is caused by a missing add-on "Animation Nodes". You need to install it first, to run the animation.

Animation nodes is an advances feature (IMO). I can give you a beginners crash course in Blender first, if you like. Let me know.

Thank you Eugen for the offer. I appreciate this. But currently once a month with YouTube help I will take a look into it.
The goals are only some animation stuff with physics to compensate the things our CAD won't do or probably so UV unwrapping till KeyShot is capable to do this.


C u soon!

Cheers
Marco

Hey Comomiles,

I imported the .abc file that was attached by MWo and checked the deformable mesh.
But still you can see there is no frames in the timeline.
