Thanks :) You are right. I reach the same conclusion about positioning the lights in IBL mode. I have also discovered that additional (not IBL) lights don't create shadows when IBL is on (I am not sure if it is a real discovery or I simply missed something reading the manual). I use position of IBL light for creation of shadows and - of course - so as to create proper highlights the infinite light has to be in the same position. Despite wrong assumptions - infinite for shadows, I get the proper result - infinite for highlights. After 2 year break in working with Poser and after moving directly from P4 to P6 I consider P6 possibilities as really amazing. Thank you for your comments
