As someone with very little knowledge about DAZ, do they really need to re-render every scene with a poster? Couldn't they use another tool, like Photoshop, to blur them instead?
I know the quality would drop, but I think I would rather sacrifice the poster quality and have a game than continue waiting. No game can survive a full year without updates only to receive barely the same content with just a few changed renders.
If they are indeed forced to redo everything and that is the only option, then forget I said anything. However, this situation is starting to look worrisome.
