Thanks for the input, guys!
Yeah, as I said, it's a mixture of different cars. It was supposed to be a blend of a Nissan Silvia and a 240SX, hence the roofline and the rear end. The front was accidental; I tried to make it look like an S13 but when I made the bumper it turned in to a Skyline.
Looks nice so far; I'm wondering how does it scale to the actual Blockhead?
I don't really know yet; I've tried importing the model into blender, but it's hard to visualise the proportions without seeing the model in-game, especially since the player model I used didn't bones.
Speaking of which, I'm actually trying to get the model into Blockland right now. Since exporting through Blender 2.49 is quite cumbersome I'm trying to use Torque3D's Collada importer, but sadly the engines use different model formats (Blockland uses version 24, T3D version 26). I've asked the GG community about this issue; if they can't solve it then I guess I'll have to do it the old way
