Forums are very important to us, and something we are regularly monitoring.
However, we currently cannot guarantee response or fast response time for all posts as the team’s schedule might require full focus on other tasks or simply personal time (holidays,…).
Could you detail or give examples that make you say that they are “dead”?
When I check the HDRP forum page, many posts are very active (600+ replies on the Volumetric cloud thread started 18months ago! ), and indeed a few are unanswered, but in average I would not say it is too bad for a small team.
