thank you very much for your advice @adrian2301 I will take them into consideration and I will try to put them into practice.
I fell into a lot of problems in this course such as when I have to activate the dyntopo and when to take it off.
so I had it permanently open and this made the mesh have too much resolution so it delayed my computer and I had some problems with my digitizer so all this made me a little angry and I’ve exhausted my patience.
btw thnx again for your interaction . 🙂
