Denoting an attribute as "Tex"

[archo_p]

I have been needing to make some custom utility UV sets for use in things like Unreal nDisplay and other technical usages of texture coordinates.  I am using some atypical techniques to create and convert P and other attributes from second inputs on attribute wrangles and such, all is fine for this, but viewing the UVs has been tricky.  What I'm wondering is if there is a way to get a vector attribute to be "tagged" with the Tex "sub-type" so that it is available in the UV Viewport auto attribute list.  For now I've had to always create my UV attributes with a UV Texture SOP and then set those attributes to my results in a wrangle so that they maintain this mysterious (Tex) signifier you can see when getting info on a node next to the attribute ( for example : "uv0 3flt(Tex)" ).  I'm just wondering if there's a way to add this "tag" to an attribute down the pipe instead of via a UV SOP that initializes the attribute, thus making it appear in my list of uv attributes in the UV Viewport.  I can't discern an option for this in attribute create or otherwise, nor can i find  an official name for this attribute "tag" or "sub-type", anyone know?

 

Thanks!

Hi P Sis,

there is a way to apply metadata to attributes (ie. "texturecoord") with the VEX function setattribtypeinfo().
