Just to say, If I make a creation, then I need Poser 11 ... there I have the Simple material room = Fast basic texture setup, I have the essential Py scripts for creations that do not woks in New versions, so stuck on 11 for creations .... then poser 13 for renders and compatibility, further texture setup, Special effects need Poser 13.0.339.0 Superfly works just fine for Promo renders, but well Firefly is broken in this version, can't render with the Backgrounds these change to 1:1 .... this issue has been fixed in Poser 13.1.449 except of the discrepancy of the Firefly render. so back to poser 11 to render correctly in Firefly. Rendering in Superfly ok need to open 13.1 up, if with clouds or 3D textures then 13.0 .... Preview renders using the Tear off option in Poser 13 still not working giving a black Image then again back to P11 .... with time a user knows what works in witch version but actually this should not really be happening all the time else ending up with 10 additional versions every year :)
