how to see more detail in a larger distance?

when I run my game I need to get really close to a modek before it shows it max detail…
how to fix?

Are you referring to a model with LOD? Or are you referring to the clipping distance beyond which objects fall out of view?

If the former, you can change the LOD scale on the camera using something like:

base.camNode.setLodScale(scale)

…or you could change the LOD distances on the model itself.

If the latter, you can change the far distance using:

base.camNode.getLens().setFar(distance)
