I have created a terain in maya and the mesh has more than 65000 vertices.
My problems.
1.How can i found out the exact number of verticies my mesh has.
2.How can i split the mesh into enough sections to get under that 65k limit per section.

  1. In Maya bring up the HUD to show the poly info by going to “Display/Heads Up Display/Poly Count”.

  2. Select a number of Edges even spaced on the Terrain in Maya.
    “Select/Select Contiguous Edges”.
    “Edit Mesh/Detach Component”
    “Mesh/Separate”
    “Edit Mesh/Merge” (for each mesh)

At this point you might have some visible seams/creases where the meshes were split. You can fix this by selecting the bordering vertices and doing “Normals/Average Normals”.
