There are a lot of old geology assets in the game that are quite subpar in quality compared to the new ones (the rocks in daymar, The spiky ones in delamar...etc), Will they ever get replaced with better ones?
Yes, and very soon as well - we are currently in the process of replacing a lot of the old geology assets with new, better ones using the new organics shader and will continue to do so until all are on the same quality level.
