I just purchased the Urban Recreation lights and am running DS 220.127.116.11 which I think is the latest version of DS 3.
When I tried to load any of the light settings, it says something like “this was created on a newer version of Daz Studio”.
Does this software require DS 4. I prefer to work in 3. If that is the case, you might want to add that info to the main product page. Presently it just says Daz Studio, with no version number.
