Hi,
How would I go about getting access or creating a point alpha value in a vopsop .In a point sop I might use $CA *0.1 .

Rob

alpha by default is just float attribute called Alpha (capital A), nothing fancy going on in Point SOP
so just create it within VOP SOP or modify or do the usual

Another diamond Answer for the notebook ! Thanks

Hi, tamte and Rob

I would like to know how to create alpha besides using point sop and found this thread but I am still not sure which is the right tool in vopsop. Could you explain where I can find it?

I was trying to use wrangle node to set it too but I can't get them to work with the vexpression below


float alpha=.5;
@Cd= {1, 0, 0};

or

vector4 @Cd= {1, 0, 0, .5};

Any idea how I should correct them?

Hey davidave,

See attached hip file.

Remember capital A

Alpha is a separate attribute from Cd, so to make it, you'd do something like:

@Alpha = .5;
