We cover how to use the new polybuild tool in Blender 2.81! The Polybuild Tool can speed up your retopo work a lot, and it's an awesome addition to Blender. In this tutorial, we cover how we'd use Polybuild to retopologize a creature head.

Tweak Points - Left Click
Delete Polys - Shift + Left Click
Extend Edge - Left Click and Drag on an edge
Create New Polygon - Hold down Ctrl while hovering over an edge/vert.

  • A tip regarding snapping. Activate Vertex and Face snapping by clicking on them both in the menu while holding shift. That way you can activate multiple snapping options at the same time. Also super useful when dealing with retopology, since Vertex snapping helps with precision snapping like at 11:33 where you try to merge one face to another when trying to delete unwanted geometry (With this option you can also have a very low Merge by distance number since it will snap a lot easier with Vertex on.), or when you use the Poly Build tool to fill empty geometry

    This is an incredible video, so helpful & such great characters you guys are. Cannot be more thankful guys, bless your whole life

    One trick I use to avoid that awkward moment where you can’t auto merge the verts is to double tap g on just a single very and smash it into the one I want to merge it with. If auto merge is on its so much faster than hand placing and hoping it’s close enough. Great vid.
  • Really exciting that Blender is working really hard to not only add tools but also make them very easy to use.
  • @ChrisAllenMusic
    Great tutorial! I don't retopo very often, but I come back to this video every time to remind myself of the great tips here. Thanks!
  • Perfect! Thank you so much for this concise and direct to the point tutorial.
  • @ninjabuddy1
    I'm trying to learn blender and even though I learned about retopplogy a couple days ago you almost make it look easy enough to try
  • 12:21 Subsurf also gets rid of your triangles, and replaces them with 3-verts. In general it turns N-gons into N-verts.

    awesome presentation, subscribed
  • @Podings
    Ah, thank you! I hadn't been able to figure out what this tool was supposed to do.
  • YES! Finally, a more efficient tool for Blender’s retopo that sends Quad Draw running for its money! I need to retopo my alien model that has 400,000+ verts and this was definitely an awesome addition to Blender! ;)

    Lol sounds like you were having fun....great tutorial, thank you . Shoutout from Canada!!

    One tip, which perhaps might be related more to cleaning up topology (which i've spent all day doing). Having the sub/div modifier in the stack and turning it on and off. It might only be me personally, but somehow my vision can more easily see the organic loops i desire when its smoothed. and also find strange shading/normal behaviors. Anyway, nothing revolutionary I guess, but it has helped me a lot today.
  • I never knew of the poly build ..always used extrude and move. thank you
  • @moony3444
    Finally a video that teaches me how to do retpolagey I can continue on with my Vrchat avatar. This is a very helpful video.
  • A while ago I was retopologizing a character, manually, one vertex at a time, without any kind of surface snapping. It was about as much fun as you would imagine
