I will design custom map, road, or any environments for FiveM/RAGE servers or just GTAV SP.
I use 3Ds max (GIMS), CodeWalker mainly.
-Full porting/redesign/texturing.-Props, custom models.-Collision/collision fixes.-LOD & FPS optimizations.-In-game integration/resource.-Grass, Destructible objects, water animation and Audio effects if needed.-NPC navigation & nodes.
Final pricing depends on project size and complexity.
