Hi all, I am at a loss after two hours of trouble shooting, so please forgive my annoyed tone. Unity Substance support is sub-par or poorly documented... or both of those! Problem: In an effort to reduce memory, Unity will often decide to unload assets on play (even though Resources.Unload has not been called). This means that cached substance textures will be cleared (IF the substance material in question is not in the scene), which in turn means that these will immediately be regenerated which can take a while. Surely, this can not be intended behaviour? Further, this behaviour and how to control clearing of substance materials (if possible) is not described in the documentation. Last but not least: As pro users (but without a support subscription), exactly where should we turn for answers to questions such as this one? I highly doubt a Unity rep will provide an answer here, nor will they likely respond to the bug report I filed. Should we have to pay for monthly support to be able to get to the bottom of issues such as this one? Sigh! Well, many thanks in advance to anyone able to shed a light on these issues!
