1) If you're new to car modelling it would be best to choose something that you would be relatively easy to create rather than a car that has too many awkward features. You can find a decent range of car blueprints at the following web address;
Typing car blueprints in to Google will bring back plenty of blueprint web sites.
2) Once I've found my blueprint I'll copy and past it into photo editing software such as paint or Photoshop. Your blueprint should have three perspectives; top, side and front. Select the top perspective by using the selection tool, right click on it and then choose crop. Save as a j peg file to your Cinema 4d folder and then do the same with the other perspectives. Make sure that the front end of the car is facing right for the side perspective.
3) Open up Cinema 4d and choose the four way perspective. Go to edit - configure - in the top view. In the attributes manager go to back and click on the image button. Locate your top perspective image and open it up to load it to the screen. Do the same for the right and front perspectives. Make sure that the images are facing the correct way. In the top view the front end of the car should be facing down and in the side view the font end should be facing right.
4) Now comes the tricky part. Add a null object and in the top view place it at the front of the car in the middle. Now it's just a case of aligning the other images so that the null object is situated at the front of the car in all viewpoints.
It's important to take time setting up the blueprints otherwise problems will occur down the line. Well, we've come to the end of the first part of the tutorial. Hope it went OK. Any comments would be appreciated. Thanks. That's all for now folks.
