Auto retopology plugin for ZBrush 2021, 2020, 2019.1.2 - ZRetopoIt

Iterational auto retopology / cleanup plugin for ZBrush 2021, 2020 and 2019.1.2 based on ZRemesher.

With no mesh distortion, smoothing too much and 100% saved mesh form.

Short demo video. Classic midpoly retopology. Standart plugin settings. ZRetopoIt version 2.8.

I am using only LazyMouse1, PGrFromPaint,  and S5* buttons in this video.

Short demo video.  Lowpoly retopology. Same mesh with polypaint structure. ZRetopoIt version 2.8.

Showreel demo video for version 2.4. 

Starting from version 2.5, I added retopology hotkeys. It's retopology presets for Hardsurface and Organic meshes:

Keyfeatures:

It works for following mesh types:

• Organic surface: classic sculpting via Dynamesh and Polypaint polygroup edges later for full topology control.
• Hard surface: after Snapshot3D via Spotlight tool, or boolean operations.
• Cloth surface: after Extract and Cloth simuluation.
• Expermenal lowpoly retopology for organic surface via LP hotkeys.

It fully controlable via AdvancedSettings and MainSettings submenus for ZRetopoIt button and Hotkeys.

It can retopo all visible subtools via ZRetopoIt button, or single subtool via Hotkeys submenu.

Full documentation for version 2.8 available here.

Full documentattion for version 2.5 available here.

Updates are free. Forever. Any questions? Please PM.

Plugin was tested in ZBrush 2021, 2020 and 2019.1.2 on Windows 10.

Now the most stable versions is 2.71 and 2.9f with two retopology algorythms.

You can quickly switch between algorythms via UseLegacyAlgorythm switch in AdvancedSettings submenu for version 2.9f

All old plugin versions are included in digital download in ZIP archive.

Quick start guide for:

 Classic organic surface retopology:

• Dynamesh your subtool to high resolution (> 1500). Fill it with white color.
• Enable LazyMouse polypaint preset switch . Polypaint your polygroup edges with black color.
• Press PGrFromPaint button.
• Press S5* from Hotkey submenu.

Lowpoly organic surface retopology:

• Dynamesh your subtool to high resolution (> 1500). Fill it with white color.
• Enable LazyMouse1 polypaint preset switch . Polypaint your polygroup edges with black color.
• Press PGrFromPaint button.
• Press LP6* from Hotkey submenu. It works nice for ~2.7 Mil point count.

Hardsurface retopology:

• Create your hardsurface mesh via Snapshot3D feature in ZBrush. Demo video with timecode link.
• Press H5* from Hotkey submenu.

For all hotkeys:

• Mostly common used hotkeys marked with * mark.
• Prefixes: S - organic surface retopology. H - hardsurface retopology. C - retopology for cloth surface after Extract.
• LP - Lowpoly experimental retopology with polygroup auto relax function enabled.
• For all hotkeys bigger number after prefix = less points.
• Hotkeys are preconfigured for PolishIterate, ZRemesherIterations, CleanupIteration sliders and PGrRelax function.
• You can tweak plugin settings via AdvancedSettings and MainSettings plugin tabs for all hotkeys.

Feature request and Hotkeys update.

- When ZRetopoIt will start retopology it will auto select white color as main color. Now you can see what plugin is doing.

I also forget to change sometimes main color to white. Now this step is automated. No more black meshes in viewport.

- PaintStart and PaintContinue buttons.

PaintStart - will fill your seleted subtool with white color. It will change MainColor to black and SecondaryColor to white and select default painting brush.

PaintContinue - will change MainColor to black and SecondaryColor to white and select default painting brush.

Now you can quickly start drawing your black colored polygroup edges. Please hold Alt key to remove them with white color.

- LazyMouse4 preset removed. Now we have only one LazyMouse preset - it's much more accurate for polypainting.

ResLazyMouse - will reset LazyMouse settings to default ZBrush values.

Now you can quickly adjust LazyRadius via L10, L20, L30 and L40 hotkeys in main plugin UI.

- New retopology hotkey presets (LP1*, LP2, LP3, LP4*, LP5*, LP6*, LP7, LP8) with relax function enabled.

They are really useful for getting lowpoly meshes.
