Aarrrgrgggrrhhhhh ....
Someone already have my same idea : 3D Zelda style game with 3D tiles



And it runs very fine with good smooth animations :

They use some sort of semi realistic textures or cartoon, but not simple plain colors patterns. I love a their style , it's also that toon style i go for, but not with detailled textures.

Well perhaps i'll switch from 3D tiles, to terrain ?
But 3DGS is not the engine at all for terrain based games.

And for textures, i'll try semi realistic or will do some detailled toon texture, but no more "Pokemon" like !

OR i'll have to go Full pixel retro like some NES game ?
