8.30: Agisoft Photoscan for photogrammetry processing > industry standard

22.00: Photogrammetry processing: low quality first; produces point cloud; define working area; build dense cloud; generate mesh; generate uvs and textures; export.

30.00 When doing CosPlay costume; start with a head scan; not about this project.

Zbrush

32.00 Starts with a sphere of clay.

35.00 Smooths the face surface using Smooth brush.

Method:

1. Clear mesh around the figure; lasso brush hide
2. Rebuild topology with subdivision levels;
3. Creating UVs with UVmaster
4. Go back into PhotoScan to reproject the texture at higher quality

1. Clean Mesh

To identify mesh islands: Polygroups > Autogroups

43.30 To close the base: Geomotry > Mod Top > Close Hole

But it also closes areas between arms and body.

44.30 Use Sculptris Pro to modify the edges; when you push inwards the polys disappear instead of compressing and bunching up.

'When Sculptris Pro mode is off, ZBrush sculpting relies on the existing vertices of the model to produce the deformation. With Sculptris Pro mode, ZBrush creates any necessary vertices where they are needed before moving them.' http://docs.pixologic.com/user-guide/3d-modeling/modeling-basics/creating-meshes/sculptris-pro/

2A. Rebuild Topology with ZRemesh

Duplicate mesh > ZRemesher '20' on slider means 20K poly target

When glitches are smoothed out, run Zmesh again:

3. Create UVs

Before using UV Master, assign polygroups to make UV Master's job easier:

53.00 He's not working on a Clone because he has no Polypaint or Subdivision Levels. Clone is useful with Polypaint and Subdivision but not obligatory and here is not necessary.

2B. Rebuild Topology with Subdivide and Project

53.30 Subdivide the polygrouped mesh twice.

Always save a Morph Target in case there are artefacts or problems with the new geometry. You can use the Morph brush to return those areas back to original geometry

55.00 Project first onto lowest level of subdivision. Why? It's faster. If it's successful you can proceed to the next level. Best to fix artefacts at lower levels first.

Exports OBJ labelled as reUVs.

4. Reproject texture at higher quality

Agisoft

Reload project in photogrammetry software and import the Zbrush OBJ file.

It will replace the mesh with the new mesh.

1.08 Export this new texture.

Zbrush

Import texture; V flip; assign texture to model.

Photoshop: 1.09.30 Load texture > greyscale > vertical flip. Add contrast. Export as a TIFF, no compression.

Zbrush: Reload texture as Displacement Map in Alpha channel; click Mode.

1.12.20: Store Morph target before applying Displacement mesh.

Transfers details onto scan surface.

1.14.00 Reorient model by changing to ortho and using gizmo.

Makes the bottom 'level' using Move brush.

Alt Method: Texture as displacement map

37.00 Use the texture data to improve the model texture:

• Subdivide model to give 4 times as many polys;
• Re-import the texture as an Alpha;
• Assign to the mesh as a Displacement map;
• Click ‘Mode' in Displacement Map area

This method does not work here as the texture is too noisy.

ZBrush 3D Printing Tutorial: Preparing 3D Sculptures for 3D Printing

ZBrush is hands down the most popular and powerful digital sculpting software out there. That's why this program is mainly used for designing figurines, sculptures, game characters, or any other design that needs an organic shape. Some users have trouble turning these 3D models into 3D prints – and that's where we come in! In this hands-on tutorial, we will show you step-by-step how you can prepare your ZBrush models for 3D printing.

Tutorial Overview

3D printing a ZBrush model typically requires three steps:

• 1^st step: It all starts with you sculpting your piece of art with ZBrush and then adjusting it for 3D printing. This includes checking wall thickness, merging objects together, and hollowing the model (if needed).
• 2^nd step: After the modeling part is done, you can optimize your design with the freely available Decimation Master plugin. This will allow you to reduce your poly count while keeping a high level of detail.
• 3^rd step: The last thing left for you to do is to export your design as a 3D printable file. With 3D Print Exporter you will be able to export your 3D model as an STL, WRL, or OBJ file.

So let's look into this in some more detail now.

… and then turned into a stunning Sterling Silver 3D print.

1^st Step: Preparing Your Design for 3D Printing

Before being able to print your model correctly, you will need to prepare your design and adjust some things here and there.

• Material Guidelines: If you know which material you want your 3D model to be printed in, be sure to learn more about the specific design rules for the material of your choice. You can find these restrictions for i.materialise's materials right here.
• Watertight Model: Your 3D mesh needs to be watertight. Ask yourself the question: if I were to put water inside my model, would it flow out? If that's the case, then you need to find those holes and close them. Sometimes this process is also called ‘creating a manifold model'. You can find more about this here.
• Wall Thickness: It's important that your model sticks to the minimum wall thickness required for your material (learn more about minimum wall thickness here). You can check if your object conforms to the minimum wall thickness by using ZBrush's transpose or move tool. You can learn how to use this tool in this explanation by 3DHubs.
• Merging & Hollowing: If your ZBrush model consists of several elements (SubTools), you could already combine them into one mesh by using the merging tool. Besides creating a single continuous mesh, Dynamesh can also help you to hollow out your design. Hollowing out your model might help you to cut down 3D printing costs. We've got a good summary about this right here.

Checking the four points mentioned above are vital for a great print. However, we also encourage you to do an overall check. Take a look at your handy file preparation checklist to ensure you will get the exact result that you wanted.

2^nd Step: Optimize Your Design with the Decimation Master Plugin

3d Printing Designs

Your ZBrush 3D model typically has an incredible level of detail – and is therefore also quite heavy. While this is perfectly fine when modeling within ZBrush, it can make things tricky when you want to export your file to different software or if you want to 3D print it. With i.materialise for example, your file size should not exceed 100 MB.

That's where the freely available Decimation Master plugin comes into play. In a nutshell, this plugin allows you to greatly reduce the poly count of a model while preserving the high-resolution detail.

Don't worry about losing detail information for your 3D print. Printers typically do not need any detail information that is smaller than 0.01 millimeters since they cannot print at this level of detail anyway. Avoid increasing the file resolution to more than 0.01 millimeters, however, in order to make sure that the triangles which make up your design won't be visible. We have a dedicated tutorial about file resolution here, in case you want to learn more about this.

In the image below you can see an original ZBrush file with a poly count of 11,000,000 (left), and an optimized 3D model with a polygon count of 750,000. While this dramatically reduces the file size, the level of detail practically stays untouched.

3^rd Step: Export Your Design as a 3D Printable File

The final step before 3D printing your ZBrush model is carried out by the 3D Print Exporter plugin, which is already included in the ZBrush 4R7 installer.

This plugin is very intuitive and only takes a few minutes to use.

• Open the plugin: With your model selected, open ZPlugin and select '3D Print Exporter' from the menu.
• Scale to preferred size: Click on 'Update Size Ratios' to capture the ZTool's bounding box size.
  • Choose your units: millimeters or inches.
  • Change one of the three sliders to define the size of your 3D print.
• Choose SubTools: Choose if you would like to export all SubTools, only the visible SubTools, or just the currently selected SubTool.
• Select file format: Finally, select the file format you want to export, i.e. STL, OBJ or WRL. If you choose WRL or OBJ, you can of course also export texture files.
