Very detailed dual artillery turret with hardpoint.
Included files :
.max (max 2010) file - with pivots set to allow both barrels to rotate as well as the entire turret as shown in renders above.
.obj file - direct export from the above .max file
.3DS file - direct export from the above .max file
Animation info : in the .max file, open the 'dual_arty_turret' group and rotate the barrels first, before rotating the entire turret. This will make animating easier versus the vice versa approach.
For both the .obj and .3ds file you will have to set the pivot points and proper grouping manually first.
