Just found some vids that give ideas about how to start the sculpting within blender right from the lowpoly version of the model so there's no need to retopo later.
Didn't test it, though. I will see.

In 3D Coat you can also import the Low poly model in the
Voxel room and start sculpting !

I already sculpted low poly models in BLender after subdivision to bake the normal map on the low poly model
some years ago when sculpting appeared in Blender.

Even on 2.5 sculpting is too much slow and it's hard to
compete with 3D coat and all it's functionnalities of sculpting(brushes, hide and delete voxels, layers, voxel tree etc ...)

The big advantage Blender it's FREE and Evolving constantly.

news: i have to go to switzerland for the next half or hole year (i have to work there for a while).

So my time is to short to bring my model to an end.
So i will contribute it to the comunity, for free!
I hope u will do a low-poly version with normal-map, and maybe texture....
also to contribute it the gamestudio-community.

So i'll start a nea thread under contribution, called - StreetcopMuscle


SO have fun with it!

Ciao

thanks Maslone1 !
Juts put it with a megaupload link or another in Obj format !

I'll make the low poly version with normal map, and basic texture color/specular.

If i have time :
-make some edges on pants more hard
-make a version with a simple Tshirt better for character before going to fight or FPS
-rig it, and animate with basic animation (idle, walk, run, punch, kick, crouch ...)

FIne... the link is in the new thread (contribution-thread), but you already saw it, ... so i can't wait to see what other people can do with my "Streetcop"

Hey whats up with my model?
Anyone did some update?

In switzerland i've started a new low-poly model

"Whitebeard" from one-piece
