In this video you will find out how to use simple spline shape to create surface subdivisions in diagonal direction. Also you learn how to use “delete mesh ” modifier to create a random subdivision effect.

This tutorial demonstrate use of Blend controller to change the pattern of surface cladding.

Morphing closed shapes

If you know MAX-SCRIPT or C# you can now write controllers for PARA 3d. This video explains the user controller for max-script users and how to share the new controllers with other Para 3d users.

In this video we learn how to use an animated parameter to create a dynamic surface paneling.

This is an advanced tutorial in Para 3d which demonstrate the usage of logic , test and condition controllers.

Para 3d Surface controller does not deal with trimmed surfaces and non-quad polygons in boundary of a trimmed surface. To solve this issue you need to map the entire surface (untrimmed surface) and then trim the result geometry with the border you like.
The process is still parametric if you use Para 3d compound node.
In case you have trouble following this tutorial please make sure you have the latest Para 3d (4.64 ) and try to create a reference copy of the first compound node and add a weld vertices modifier.
