are there any way to export character/3d model from game view after customization it ?customization are possible in unity but are exporting the models to other programs after edit in game view possible ?
that’s video for customization for who don’t know it
Not out of the box. You’d have to write your own exporter or see if one exists on the Asset Store that does what you need.
did you know any tutorial for that ?
For what? If you’re exporting to an established format then I’d start with the documentation for that format. If you’re making one up then you can do whatever you want.
