Hi,

Could draw curve as wireframe(not band or tube) in lop OGL viewer?
I want curves to be drawn as helper icon in my HDA just as Control Sop in Object context.
Anyway?

Thanks!

Add the primvar houdini:gl_wireframe to the curve primitive and it will render as regular GL lines.

In case anyone else has a problem figuring out how to do this in practice, here's an example.

Appears to work just the same with the usd_addprimvar line commented out so I'm not sure if it's good practice to use it or if it's superfluous as I'm a solaris beginner. This is in an attrib wrangle LOP :

I attached an example file showing a few other ways you might set the primvar value.

@malexander - What defines which attributes show up under schemas in the edit properties parameter interface dialog? I would think this attribute would fall under some houdini specific schema so you don't have to memorize the name.

Thanks @jsmack, this is really useful.

I agree about the edit properties schema thing, that's the first place I looked to try and set it.
