    Tip: Massive Blender Slowdown.

    Grant (astute)
    posted to: Sculpting the Major Forms Pt. 2

    Over the course of this tutorial, I've been improving my sculpting flow with the use of hotkeys. Namely, the common ones like Inflate(I), Smooth(Shift), Brush(B), Size(F), Strength(Shift + F).

    However, in this series, I've been using Polish more(as per this course), which is Shift + 4.


    I kept running into a scenario where Blender would start to chug after a while. I thought this was strange, since my geometry wasn't overly dense or complex. As it turns out, CTRL + 4 is Add Multiresolution(Subdivision Set). I would occasionally hit Ctrl instead of Shift, adding a multirez to my sculpt unconciously, multiplying the geometry by orders of magnitude.

    If you are running slow, it might not just be an optimize scenario. Check to see if you've accidentally added a MultiRes to your surface. After doing it three times during this session, I ended up unbinding Subdivision Set in Sculpt mode via the Input settings.

      Did I say Shift + 4 = Polish brush in this course? I didn't know that was the hotkey for polish brush...maybe I did back then? 😅

      I did know CTRL + number added a subsurf modifier in Object Mode. Looks like it adds a multires in Sculpt mode. Learn something new everyday.

      Thanks for sharing this astute. No doubt someone else will experience, left scratching their head.

      Oh! I'm sorry, I didn't mean to imply you said or did anything wrong with this tutorial. I was following along with your course and experimenting with the different brushes, and ran into a similar slowdown issue as you do.  Your issue does not appear to be related to mine, as I never saw a multires on your sculpts, and optimize was not clearing up my issue.


      As for the shortcuts, I searched the web for the common ones used in this tutorial. Shift + 4 happens to be Polish for me(1-0 number keys select the first 10 brushes). Shift + (1-0) selects brushes 11-20. This could change based on the brushes you currently have, and what order they are in. YMMV.


      But yeah, as I was using the shift keys to select Polish, I would hit CTRL instead and inadvertantly add a multirez to my sculpts on top of my already dynotoped mesh.

      Thanks for this course, btw. It really throws you out of your comfort zone in a good way.
