Optimizing your 3D object

You can only use Meta Spark Toolkit to optimize one mesh at a time.

If your 3D object is made up of multiple meshes, try combining all the surfaces into one mesh or optimizing each mesh individually before combining and exporting as one.

Select your mesh

Select a mesh to get started. It will then be listed in Meta Spark Toolkit, under Mesh.

Check triangle count

The Optimization section in Meta Spark Toolkit displays your mesh’s current triangle count.

A checkmark to the right of the count will let you know that the triangle count is in line with the Meta Spark Technical Guidelines.

If you see a white exclamation point instead, the triangle count meets requirements, but the mesh will perform better if reduced.

A red exclamation point indicates that the triangle count is too high and you’ll need to reduce it.

Reduce triangle count

Use the Reduce Triangles section to make your mesh as lightweight as possible without negatively impacting the visual quality of your 3D object.

Try reducing the triangle count by different percentages and checking that your object maintains its realism and shape before applying any changes.

For example, to reduce the triangle count by 50%, follow these steps:

1. In the box below Reduce Triangles, enter the number 50.
2. Press enter and check the appearance of your object from all angles.
3. Click Apply to apply the changes to your mesh.

Clean up

Next, under Clean Up Mesh click Apply. This will further reduce triangle count by repairing and removing geometry that could cause issues when exporting to Meta Spark.

The clean up includes:

• Deleting loose geometry.
• Making planar faces.
• Splitting non-planar faces.
• Splitting concave faces.
• Degenerate dissolve.

Scale and positioning

The scale and positioning displays your 3D object’s height and lets you adjust both the height and pivot position.

Set Height

A checkmark to the right of your object’s height will let you know that it follows the Meta Spark Technical Guidelines.

If you see a white exclamation point instead, the height meets requirements, but the mesh will perform better if reduced.

A red exclamation point indicates that you’ll need to reduce the height.

To set the height:

1. In the Scale section, enter a value in the box below Height.
2. Choose either centimeters, inches or feet from the dropdown menu to the right of the Depth box.

Set Pivot Point

Click Center or Bottom to shift your mesh’s pivot point to a desired position.
