As a quick guide - using shipcontainer textures from cgtextures.com to start off some play.
Snapshot from Maya - showing Cube Poly with UV Layout.
Then a quick knock up bumpmap - using the original UVmap and clone brushing out the text...otherwise the white text will have relief.
Turnaround model in Unity
Quick Evaluation and Reflection of where next...
- Several Versions of the Crate - for variety - particularly colour.
- Geometry of Ship Container can be more detailed - particular door and latches. WATCH POLY COUNT!
- UV Map is tooo simple - need unique sides and top / bottom too.
- More refined bumpmap - and specular map to control specularity.
- Hmm - Interior and working doors?
- Text on Shipcontainers - particularly numbers would start looking repeated... need some replacement.
- LOGO on Shipcontainers - hmmm... need to start thinking of a backstory to support this?
