Why triangulate a mesh

At the bottom is the low-poly with the normal map baked from the high-poly. The mesh on the left use a triangulation identical to the one used by Substance Painter when baking. The mesh on the right doesn't and display black artifacts. This is because there is a mismatch between how the normal map was baked and how the mesh is currently triangulated.

Substance 3D bakers Guides. Triangulating before baking 3D Meshes can be defined with polygons with multiple border edges per face. How can triangulation affect a mesh? Why triangulating before baking? To create a triangulated mesh from data in the project, right-click on the Meshes folder and select from the New Triangulated Mesh options.

When you select the Shared with option, the mesh will be updated when the extents object it shares is updated. The Use error threshold setting lets you exclude data points that fall within the threshold.

This can be useful if you are using a large dataset and you require a more coarse surface that omits some data. When Use error threshold is disabled, the mesh will follow all the data.

Here, a mesh created from points has the Use error threshold disabled. The mesh follows all the points:. Here, a mesh has been created with the Distance set to The mesh ignores points that fall outside the threshold:.

You will be able to change the Use error threshold setting once the mesh has been created. If you are creating the mesh from a polyline, you will be prompted to select an existing polyline or draw a new one. If you draw a new polyline, it will not be able to be used elsewhere in the project unless it has been shared.
