Mapping node for texture bitmap

Good evening (o;

I have a hard time when trying to map a texture bitmap via the mapping node…
when I disconnect it I can see parts of the bitmap being rendered…but when I connect the mapping node to the texture bitmap node I am totally lost which mapping to choose and what values for position/rotation/scaling to use…

Tried now for an hour sliding values back and forth but to no joy (o;

thanks in advance

If you dont feed the mapping node with starting texture’s coordinates, it won’t know how to tweak texture’s coordinates.

texturecoordinate

Just discovered myself when I tested with a simple cube and a simple PNG file (o;

Though I used the “Generated” output to connect to the mapping node…

BTW: What is the difference between all the texture coordinate node outputs?
