yes, we do have a plan for this feature. it would be nice to take the screenshot inside the editor and then have the option to upload to a gallery from within the engine.
There theme modus on the demo site looks awesome, and i think it can be styled to match the rest of the websites. obviously its another sign up system though. i will see when i can fit it in.
just been playing around with some alternate skyboxes and made a moon with robots quickly to suit a scene for this 1 loving this engine the terrain tools alone make it great, add the rest of the features and the amazing performance of fps and your defo onto a winning software imo
