When I start up blender and go to sculpt mode in the drop down menu, there is no drop down for the remesh function and I don't have some of the brushes at the bottom of the panel such as the filter. Any suggestions?
Sounds like you're using an older version of Blender. This was recorded with 2.81 I think. Current Version is 2.83.2 which has even more brushes. I'd recommend using 2.83 and ask on the Forum if you run into difficulties/differences...
