I have a question related to this. I'm using Poser 5, and doing my first lighting pak. I have a Poser 4 user betatesting it for me. The problem was not having the .rsr files in place of the .pngs so that Poser4 showed the thumbnail in the library instead of the shrugging image. How do I convert/what do I use to convert the .pngs to .rsrs? Thanks for any help you can offer!
