I build a new cylindrical hopper and I have to map the side of the wagon.
My texture come from a photo and just the side dimensions are 1130 X 200 pixels.
Now I want to map this picture in a 512 X 512 tga template file.
I have 2 possibilities : ( I know I can use 1024 X 1024 but the question would be the same, I think.)

1- A simple surface of 512 X 117 pixels for a total of 59,904 pixels to display the texture.

Like this



2- A greater surface of 512 X 200 pixels for a total of 102,400 pixels to display the texture with more deformation.

Like this



I don't understand why the result with the second surface is not really better on the model.
The number of pixels available is a little bit less that twice.

Look this for the comparison




The upper wagon is mapping with the 512 X 117 texture.

Is someone can explain me simply why? and to suggest to me the better way to fellow.

Thanks in advance
