Differentiating Polygon and Polygon Mesh

[nicholas_yue]

Hi,

 

  In a Sphere SOP, there is a choice of Polygon or Polygon Mesh

 

  Inside my SOP, I am using GA_FOR_MASK_PRIMITIVES() to iterate the input

 

  What mask can I use to differentiate between Polygon and Polygon Mesh from a SOP like Sphere ?

 

  Or, is there an alternative way to differentiate them ?

 

Cheers

Polygon creates triangle polygons while Polygon Mesh creates quad polygons. In both cases, polygon primitives are used, just with different number of vertices.
