How Long Does It Take To Make A 3d Model. Please photorealitic model how long educated estimate in hours. I completely understand that it will take me years to get that good to make it at all let alone at the average speed.

One scenery object 4 8 hours. But i still need to know the average speed for the sake of estimating how long it will take me to do everything i want to do with my 3d project. Rigging a character 4 8 hours.
And of course it depends on your sculpting skills as to how long it ll take and how well you ll make it.
Animating a character per short animation 1 2 hours. That depends almost entirely on you. One level texture 1 2 hours. It is really up to the individual how much time they want to spend doing it.
