this job was done with freestyle to simulate a drawing done with hand.
The crinkled paper is a good texture and the car is a nice hand drawn car. I've downloaded the file.
But the result shown in the image doesn't look to me like the car is actually drawn on the paper. The outline is too smooth. I would expect to see interruptions in the outline of the car wherever it passes over a crinkle. Also, I can see what looks like a shadow underneath the car, as if it is a 2D plane standing on the paper.
when i did this job i don't thought in this question of the interruptions in the outline and about the plane i not understand because does not have any drawing in the texture.Thank you for the tip i will remember of this in the next job with freestyle.XD
Ah yes, I see the problem. One solution would be to capture a freestyle render of the car alone, with transparent background, then import that back in as a texture.
But to get the outline interruptions, you would have to shrink the car texture against the crinkled paper, and therefore the paper would have to be a plane with physical crinkles in it.
It could be an interesting exercise.
Unless of course that is what you intended - a slightly translucent cut-out of a car - in which case, I would say you succeeded pretty well and it is just the description that was not clear to me.
I like the car molel to use in my animations ^_^
Keep up the good work.
