I am trying to set Cd to the value of an attribute in vex but I do not know the attribute type ahead of time. Assuming the attr is an int, float, 2float, or 3float I want Cd to become:

int -> {int,int,int}
float -> {float,float,float}
float2 -> {float2.x,float2.y,0}
float3 -> {float3.x,float3.y,float3.z}

So I am doing something like (vertex wrangle in this case):


if st is a 2float then this does not evaluate st correctly. How do I handle setting Cd when st could be any of int, float, vector(3float), vector(2float) ?

If I can determine 2float vs 3float then I can do:

or

as needed to get the correct result.

the functions attribtype() or vertexattribtype() group float and vector types into one return value.. So they don't really help.

You can use attribsize to get the length of the attribute.
Something like this should work for the case of int, float, float2, or float3:

That is perfect! Thanks!!
