I am loading a houdini asset in unity but for some reason the soft edges became hard edges and the verticecount tripled.

Is there a way to prevent this?

im using houdini 14.0 and unity 5.0

thanks anyway

Houdini's Point are not same with Vertices in other 3D applications.

For example if you have simple Box in Maya with 8 vertices and set Normal's angle to some bigger number for achieving soften edge , this box has 8 vertices again , But if you have a simple Box in the Houdini and use Facet SOP for setting Notmal's Angle (to achieve Harden or Soften edges) , Houdini use unique point for each primitives (face) , in this case you have 24 vertices !

I think that's reason for why vertices count is tripled.

Because these points for primitives (faces) aren't shared (they are unique per primitives) , So your Normal's angle in the Unity is Hard !

You can use Vertex SOP node for defining normal's angle instead of Facet SOP.

I think this is your answer :wink:
