Instancing multiple geometry

[Navneet Arora]

Hey guys,

I am trying to create a probability of instancing multiple objects to points. I have different set of shapes so what i want is that some shapes should be there in more amount as compared to other shapes. Any idea as of how can i create this?

How did you setup instancing? Easiest way is to use same shape several times instead of just once.

You can create a point attribute called 'instance' who's value is the path to the object inside Houdini, or 'instancefile' with a path to the geometry on disk. If you put the below code in to an attrib vop you should get 20% of your points pointing to instance2 object and 80% pointing to instance1.

 

if(rand(@ptnum)>0.2)
    {
        s@instance = "/obj/instance1";
    }

else
    {
        s@instance = "/obj/instance2";
    }

 

 

This video from Sidefx covers everything you need to know about instancing.
