Nothing is being drawn#

Check that:

• Vertices are drawn at the correct depth. The helper Vertex.nearZ provides this z depth for you.
• The correct triangle winding order is used. This is clockwise¹.
• Colours used for vertices are not transparent.
• Your triangles have area. If you are drawing lines, two vertices isn't enough, you will have to manually give them volume as triangles.
• Your element isn't hidden behind others.
• When using AllocateTempMesh, call DrawMesh afterward with the vertices and indices slices.

If these are not your problem, start with the simple case (drawing a large triangle/quad) in a basic element and work your way upwards to drawing complex content.

Errors#

InvalidOperationException: The UNKNOWN_OBJECT_TYPE JobName.Vertices has not been assigned or constructed. All containers must be valid when scheduling a job.

You have passed 0 to AllocateTempMesh's count, which has returned an empty span.
