Product Name: OkTopo Remesher Version: 1.0.0 Date: 04.01.2025

Overview

OkTopo Remesher is an innovative Blender add-on designed for fast and high-quality 3D head retopology. In just a few clicks, you get a clean, well-designed mesh with proper edge flow and UVs — perfect for animation and texturing. Whether you're working on realistic or stylized models, OkTopo Remesher delivers consistent, production-ready results.

It’s ideal for both beginners with no topology experience and professionals who want to speed up their workflow. The interface is intuitive and minimal: mark a few key points, click a button, and your model is ready.

Using OkTopo Remesher

OkTopo Remesher allows you to quickly create an optimized head mesh with clean facial topology in just a few steps.

<aside> ⚠️ Important:

To ensure correct operation, it is crucial to follow the steps in the correct order:

</aside>

1. Select the Target Mesh — choose the high-poly model you want to retopologize.
2. Add Face Markers — place the required markers to guide topology generation.
3. Run OkTopo Retopology — generate the clean mesh based on your markers.
4. Adjust the Mesh Using Controllers — fine-tune the mesh if needed.
5. Finalize the Mesh — clean up all helpers and complete the process.

Following this sequence guarantees optimal results and avoids errors during generation.

Preparation

Before you begin, make sure you have a high-poly 3D head model you want to work with.

• The model should be oriented straight — not tilted or twisted. It can face forward, backward, left, or right, but must align with a global scene axis.
• The model should be positioned at the center of the scene (0, 0, 0) — otherwise results may be distorted.
• It's recommended to apply all modifiers (especially Mirror, Subdivision, and Shrinkwrap) before starting.
• Make sure the object is in Object Mode.

PREP.mp4

1. Selecting Target mesh

• Either select the model in the scene and press Add Face Markers

SELECTION 2.mp4

• Or use the eyedropper icon next to Target mesh to manually pick the object.

SELECTION 1.mp4

The selected object will appear at the top of the OkTopo panel in the Target mesh field.

2. Placing Markers (Add Face Markers)

At this stage, you will mark key reference points on the face. This guides OkTopo Remesher in adapting the topology.

<aside> 🔥 Critical:

It is absolutely crucial to follow the correct marker placement order when using OkTopo Remesher.

Incorrect marker sequence can break the topology generation process, causing serious errors in the final mesh.

<aside> ⚠️ Important:

When instructions mention "left" or "right," they always refer to the model’s own left and right sides, not the viewer’s perspective.

In other words:

• Left = Model’s anatomical left side
• Right = Model’s anatomical right side

Imagine standing inside the model’s head — left and right are from the model’s point of view, not yours.

Symmetrical Faces (Default)

Before starting:

• Make sure Use Symmetry is enabled.

• The model should be at the center (0,0,0).
• The correct Symmetry Axis (X or Y) should be chosen based on the head's direction (default is X).

Then press Add Face Markers and place the following 4 markers:

1. Tip of the nose
2. Left eye
3. Left corner of the mouth
4. Left ear

Correct Symmetrical Marker Placement Sequence

Follow this pattern precisely to ensure successful retopology:

The right-side markers (eye, mouth, ear) will be generated automatically via symmetry.

Non-Symmetrical Faces

Disable Use Symmetry

Press Add Face Markers and you will manually place all 7 markers:

1. Tip of the nose
2. Left eye
3. Right eye
4. Left mouth corner
5. Right mouth corner
6. Left ear
