No, not a custom brick spawn, but a vehicle
I made a simple cube, then added mounts and a collision box around it. Then I right clicked the collision box and moved it to a second layer. I parented it to Col0 (empty) and parented Col0 to shape. I parented everything else to detail32, etc. Then I setup the exporter to get the collision data from the second layer.
When blockland loaded up, a wrenched a spawn and selected my vehicle... and then blockland gave out.
But then it said this in the console before it crashed:
setWheelTire: wheel index out of bounds, vehicle has 37773831 hubs
setWheelSpring: wheel index out of bounds, vehicle has 37773831 hubs
setWheelTire: wheel index out of bounds, vehicle has 37773831 hubs
setWheelSpring: wheel index out of bounds, vehicle has 37773831 hubs

setWheelTire: wheel index out of bounds, vehicle has 37773831 hubs
setWheelSpring: wheel index out of bounds, vehicle has 37773831 hubs
setWheelSteering: wheel index out of bounds, vehicle has 37773831 hubs
setWheelSteering: wheel index out of bounds, vehicle has 37773831 hubs
setWheelPowered: wheel index out of bounds, vehicle has 37773831 hubs
Wait, what? I only have four hubs...
So, basically blockland crashes when I spawn my custom vehicle, and as far as I know, there were 0 warnings and errors in the .log.
What the heck is wrong?
Oh, if you NEED the blend...
