Sculpting on 2 joined meshes is not working as intended The problem I'm having is that when I join 2 object and make them into one and continue sculpting as a result I start getting these blobs and won't connect with previous second mesh

These were the 2 meshes that I joined (the upper rectangle one and the lower cylindric one). I intended for them to be smooth surfaces but their &quot;geometry&quot; is never connecting.
Let's say that you want to sculpt these two objects together:

First, apply their scale, then apply all their modifiers except Subdivision Surface that you just disable. Keep in mind that when you join objects, the last selected while keep its modifiers (and they will affect the joined meshes) while the others won't:

Join them with CtrlJ, then select all the meshes except one and go into Face &gt; Intersect (Boolean) and in the Operator box choose Boolean &gt; Union:

Set the origin of the object to its geometry, switch to Sculpt mode, enable Dyntopo, it works:
