Important Notes. Please Read.
Power SubD-NURBS currently only works on Organic Quad Sub-D meshes. If your mesh has a minimal amount of triangles, the result still might be acceptable. Try previewing the conversion using the demo. Converting other types of meshes such as triangular meshes are a work in progress. If you would like to help us develop it, please contact us and send us test models.
Recommended conversion steps: Subdivide your mesh using 2 iterations of subdivision before converting them with Power SubD-NURBS. If you are using the turbosmooth modifier, please disable isoline display.
For more usage tips please consult the documentation (click the "?" in rollouts and windows).
