Triangle renderers displays the particles as triangles. You can specify the position, color, normal, and UVs of each vertex of the triangle and have a full control over the shape and transformation of the triangle.
This renderer is not yet supported in all our public integrations.
Support in the UE4 plugin will arrive in version 2.6.2
Triangle custom normals
If your triangles are lit, you might want to specify custom normals for each vertex of the triangle renderer. By default, the triangle renderer can generate its own normal and tangent.
Here is an effect that reconstructs a mesh using the triangle renderer, showing the result with and without providing per-vertex normals to the renderer.
You can also use the “Normal Bending Factor” that will curve the normals and tangents depending on the barycenter of the triangle.
Triangle custom UVs
You can also specify a per-vertex UV coordinate on the triangle renderer using the “Triangle Custom U V s” feature. The tangent of the triangle will be automatically computed depending on the UVs and normals set as inputs.
The default value for the vertices UVs when the “Triangle Custom U V s” feature is disabled are (0, 0), (1, 0), (0, 1).
