I've taken some time to get my head around Blender, where I took the Austin Metro from GitHub and modified it to suit a Wolseley 16/60, my attempt is attached. I followed the tutorial but the output is entirely black.
Is this an issue with the lighting setup?
There was a fourth visible layer. I removed that and got a working render.
Now I'm missing the rotations.
Edit: On other files, the rotations work. Just not on this one. Have I broken some set-up for multiple angles? The Location and Rotation fields are shaded yellow. Is this what's causing the issue?
I solved it by clearing the Keyframes on the Location and Rotation fields.
