a question about Blender2KT

When i try to use Blender2Kt to render with the default render settings and the default lamp settings for the light, it looks very different from that of Blender renders. Its renders were below my expectations and looked untidy. If anyone one of you has successfully used Bledner2Kt, then please tell me the settings you used to improve the picture and make it look realistic. I use Kerkythea 2008 Echo. Thanks
