Maya, exported blendshapes curve tangent problem
Using Maya 2018 and exporting to Marmoset Toolbag 4 I am trying to figure out why the tangents in my graph editor will not export correctly. I make the splines so that they go into negative values on the blendshape node. This plays correctly in the Maya viewport, resulting in a squash and stretch. Upon export I receive… -
Re: Maya, exported blendshapes curve tangent problem
@Eric Chadwick , I just tried your suggestion (exporting as fbx and reimport back into maya) and the animation works as expected in Maya. I also just tried upgrading to Maya 2020, and also tried in Toolbag 3 rather than 4, all without a difference. I've also reset the maya export preferences to default with no change. So… -
Re: Maya, exported blendshapes curve tangent problem
@Eric Chadwick , is it possible to move this to the marmoset forum? Thank you. I got some help from maya area forums that might narrow things down: If I export a sphere with blendshape animations that go from positive to negative values as an fbx, only the positive blendshape values will play in Toolbag. If I export same… -
Re: Maya, exported blendshapes curve tangent problem
Moved. However this sounds like a limitation of FBX or that particular exporter. What happens if you reimport the FBX back into Maya? I suspect the exported file itself is the problem, rather than Toolbag's importer. -

Re: Maya, exported blendshapes curve tangent problem
I work alone so I am not familiar with animation best practices. Is it uncommon to use negative blendshapes? Perhaps I should just use extra joints as necessary? The purpose was for adding squash and stretch to muscles/fat on human characters. Making use of the negative value makes it easy to get realistic jiggles using… -
Re: Maya, exported blendshapes curve tangent problem
Negative blendshapes are likely an untested/unsuported case in Toolbag, if you can email example files to support@marmoset.co we can look into this more. As to why Alembic would support this: Alembic is a cached geometry file format that saves unique vertex data per frame, anything you can rig up will work with Alembic…
