I see lots of questions answered, but it doesn’t mean I know they’re the correct answer, or the best. I’ve posted and had no answer, more than once or twice. The problem with the so-called ‘logic’ or whatever that it’s already been answered is the different versions have changes that change what the solution or answer is going to be later…even for simple things. It can also make a new user disparaged if they’re unsure where/how to search for it, and when encountering lots of those problems to search for answers to…spending hours guiding themselves around a disorganized set of two message boards that prioritize more complex or ‘experience-based’ problems over others. This is partly a direct result of low-quality documentation. It’s other things too, though…difficult to control flow of information and ease of access in a forum setting, multiple causes of the same problem (such as meshes turning black, and ‘noise’), experienced users who are quick to criticize or deflect attention from new users in a forum, and probably more.
The OP is correct that a huge number of questions / problems / errors are posted that do not get answered. It would help if there were a sub-forum for each major topic forum that contained a list of the most commonly asked questions with the answers, solutions, and workarounds for those. And perhaps a checklist of things to search for that is connected to the various common questions, issues, and errors encountered. Yet some of the common problems are not always requiring the same answers and solutions, or workarounds / fixes. Newer users or not, lately I’ve seen what appear to be issues that had previously received answers, unbeknownst to the new poster, and the issue is not fixed by the popularly suggested tips and typical solution. One example I think of is the ‘blobby’ or ‘weird’ shadow reference in posts. One suggestion is the ‘blobby’ shadow is caused by insufficient mesh distance field resolution / size, while another claim is its due to bad mesh structure, and yet another potential cause is related to using a Light Propagation Volume. When a beginner in an advanced and settings-driven program, the problem encountered appears to have far more potential causes (especially unknowns) than the same problem when experienced and knowledgeable.
