creating vector attributes in a python geo operator

[Aearon]

Hey guys,

is there anyway to create a vector type attribute? all i seem to get is a '3 float' type using

geo.addAttrib(hou.attribType.Point, "N", hou.Vector3(0.0,0.0,1.0))

or

geo.addAttrib(hou.attribType.Point, "N", (0.0,0.0,1.0))

but some of the standard attributes like 'N' and 'up' need to be vector attributes

[Aearon]

and another thing,

setting string attribute values using setAttribValue doesn't seem to work either, it complains about a wrong type

any ideas?

Seems to work for me ... (9.5.252)

geo = hou.pwd().geometry()

# for vector attributes, we need to send down True for transform_as_normal
geo.addAttrib(hou.attribType.Point, "N", (1.0,1.0,1.0), True)

# string attribute
geo.addAttrib(hou.attribType.Prim, "name", "")
for poly in geo.prims():
	if poly.number() % 2 == 0:
		poly.setAttribValue("name", "even");
	else:
		poly.setAttribValue("name", "odd");

thanks edward, i didn't know about the transform as normal attribute

as for the string attribute, i tried it like this before:

attr = geo.addAttrib(hou.attribType.Prim, "name", "")
poly.setAttribValue(attr, "even");

this is the way it's done in some of the HOM Cookbook examples, but apparently this doesn't work for strings? it does work for the vector attribs i'm adding. anyway your method works fine and i'm on my way. thanks!

I've logged bug 32707 for that since that should work. It's not just for string attributes, but also for all the other single component versions of the setAttribValue() methods.

cool thanks for confirming and submitting
