View3D plugin to view/modify 3D mesh with the current image as texture

No I do not mean 3D modelling, rigging, or skinning capabilities. I mean just importing and manipulating pre rigged poses inside krita on canvas for reference and drawing help.

There is a feature request for this see here - Digital doll/puppet model - #6 by AhabGreybeard

And also check out similar feature in Clip Studio paint - https://tips.clip-studio.com/en-us/articles/6949

There is also a plugin for Krita for this here - Plugin: Blender Layer - Live 3d View in Krita
