Hi Paul
So I did save my model in 2014 and SU8. Bot times it didn’t open as an skp.
So I then downloaded the .atl exporter and exported the file only then did it open in artlantis. however it went from roughly 260MB to 1.8 Gbs.
Now that file was too heavy to even work on. It opened but froze for years.
this is the bit i didn’t understand, So i had saved a scene and deleted everything else that you couldn’t see around and save one with textures and the other without materials. the one without materials opened and the one with materials said unknown file format like all the other times i had tried to open it. which led me to believe that it was a material problem but the full white model won’t open so its not a material thing? its a size thing? if importing directly into artlantis without the .atl export there is a file size limit?
So what i have subsequent found is that if I export to .atl then the model does open but why does it bloat dramatically in size?
