This is the project I have been working on for the past week. I wanted to wait till I had it UV mapped and applied basic textures before I shared it. I found the undercarriage suspension tricky areas to get my head around. It has a lot of complex parts and finding good reference was tricky. Luckily I came across a blog in America who specialised in restoring carriages and wagons. I was even luckier to find they were also working on the same model of carriage. Good quality reference is always invaluable. I could make parts up and most people would be none the wiser but I can be a perfectionist with a strong desire to capture everything I create in a realistic manner. That meant getting my head around leaf spring engineering. I think I know how leaf spring suspension works now!
The next stage is to go back in and start building high poly models of the pieces. Then bake on some nice normal maps. After that I can apply proper textures. I like the idea of having a shiny carriage but I know it would push my skills further to add dirt scratches.
