I have an exterior shell of a hypercar almost ready, but what truly matters now is everything that sits beneath and inside it. The very first milestone is to build an accurate frame and engine-bay layout with an aggressive, sporty character. Tub geometry, mounting points, heat-shield zones, even bolt locations—I want them to feel showroom-real, so I can drop an engine model straight in without further tweaking. Once the skeleton is perfected, we can move on to reshaping and detailing the rear lights and then giving the cabin a cohesive interior that matches the same bold language. Opening doors, realistic hinge motion, seal gaps, and dashboard surfacing all need to be modeled so the car can be animated or section-rendered without cheats. I work in Blender and SolidWorks, so clean, non-destructive geometry and well-named layers/collections are essential. If you prefer Maya, 3ds Max, or Rhino that’s fine as long as interchange formats (STEP, FBX, OBJ) come back error-free. Please include examples of past hypercar, supercar, or motorsport chassis work in your reply. Showing how you’ve handled tight packaging or complex hinge mechanisms will help me lock in a decision quickly. Deliverables (per milestone) • Detailed frame and engine bay model, fully UV-ready • Updated rear light assembly, fit to existing bodywork • Complete interior with functional doors, hinges, and latch geometry I’ll review files at each stage against the reference dimensions I’ll supply and pay per approved milestone. Looking forward to seeing what you’ve built before and how we can push this project to a new level.
