I think that you already know that I consider NVIL/Rocket 3F one of the best companion for Moi 3D, along with 3D-Coat of corse.
Now Isontia has added two wanderful features to R3F/NVIL :
1) Matcap materials (long awaited)
2) The chance to capture its viewport in superhires custom resolution (up to 16384x16384) with transparent background!
Almost like Moi currently does but with the great addition of the transparent background.
Perfect to create 2D/3D image composition in print quality resolution.
Unlimited amazing exploration!
The good point is the experiment in direct online!
The bad point is the necessary time to integrate code learning! :)
Java Script + Html ?
Amazing! Some of that tools are useful also for export things in vector or 3D format that you can use in other software like Moi or any Affinity Designer.
Yes that cool but need to learn some new tools...
I see something like p5.js make the same but is 3 times less speed than classic Processing...
In any case amazing tools for "big heads"! :)
