Would Poser users be interested in this type of thing, perhaps I could get a poser user to make them poser compatible and Ill give them the skyboxes for free for doing it for me.

My files are .obj so I poser should be able to handle those.
Figures, crt files. These sound like files used for a poser model, i.e. a figure, is that a good file type for something that isn't a figure, id say these skyboxes are more like props, not sure what format the poser props are I have seen sold in many places.

My skyboxes are all boxes, they may need changing in size inside the application, say poser in this case, does poser handle changing model sizes, from what I remember of poser from years ago is that it just made or altered figures/characters, though Im sure it is capable of much more these days, I know that it has been updated many times and given many new options. I also see that Daz studio is very popular, what's the file format with that is .obj fine or does it like something else.

Thanks for the links, Id say my products compete very well with the ones show both in quality and price. Hopefully poser users will be interested in my product and use them to create fantastic art pieces.

Cyclorama, is that a part of poser, i.e. a program with poser, I did a search and couldn't find a download link so Im thinking it could be an application with poser.

Perhaps this is it and its sold separate
