This is a very simple post because I've been watching development streams, and it would be disappointing if it was the same 2 rocks for the funnel web spiders. maybe make 4 or 5 different models. And also can freeplay have caverns?
Over time more variation like this will be added. Remember you've only had the one environment so far (beach / dunes) so we have whole other groups of assets to add for new environments (next is jungle).
Not sure about caverns for freeplay - we don't want to restrict the nest layout options for anyone in that mode.
