Sprite classes of 2D to 3D

[Tio Akima 75]

I've watched Olrox using 3D models for subsituir the 2D sprites of classes

 

It is possible to replace all 2D sprites (classes) for 3D models?

 

for example, putting a 3D model for the Monk class

 

if possible, how to do it?

 

Or perhaps use another route, using a 3D monster and the player take on this way ... I do not know, can be a way forward ...

 

thanks
