It appears help command is broken in Unreal Engine 5.6 (I mean typing help in the console to see the generated HTML help that summarizes all available console commands in the engine).
Unreal 5.6 - 1146 commands.
Unreal 5.5 - 8949 commands.
So arround 7.8k commands are lost. It is a very important, since it’s basically one of the best places to investigate available options without scanning through different doc / source code pages yourself.
More concrete example - r.VolumetricCloud is missing.
Though it’s still available in the engine:
It would be great, if someone has contacts of unreal engine devs and can share this bug report, so issue can be resolved in the next iteration if 5.6. I’ll try to report it through usual bug report system, but usually it’s unlikely someone will notice.
