Hi , I 'm a beginner in POV Ray , could you help me ?
I did a render of an electronic board and I would like to change the color
of a capacitor, I checked the file "e3d_cap.inc", I made several changes, but I
am not able to change the color of the capacitor body. In fact, I can even
change the color, but the component's polarity marking disappears.
Help !!

The file "tex_elko.png" is an image, the image is mapped onto a cylinder 
by POV-Ray.

You can edit the image using any graphics programme such as Paint on 
windows.
