I'm using 19.5.435

Solaris can't generate "primvars:st:indices" when use sop uv node or import test geometry.
It's very important!
Mesh export from houdini to other software like Maya or Nuke, uv is incorrect,texture is cut.
In nuke,import usd from houdini,the geo diplay correctly in 3D view, but the color is only one pixel of texture when access scanlineRender.

Yes, how?

It'd be nice if someone solves his own issue share the solution.

Hi,

I think I am running into the same issue. I have some geometry created in Houdini. I've used the UV Flatten node to generate UV's on the vertices. I can see the UV's working when switching to UV viewport and I can see the UV date in the Geometry Spreadsheet.

However upon writing out using the "usdexport" node in SOPs I can see in the solaris scenegraph that there are no data for the "primvar:st:indices". Only "primvar:st" have data.





Did anyone have a solution to this issue? Probably something simple I am missing I guess.

The primvar indices are only required for indexed primvars. If the length of the array matches faceVertexIndices or faceVertexCounts or the length of the positions array, then indices are not required.

Hi guys,
maybe a stupid question...I'm new in Solaris. What's the difference between converted attr and indexed attr?
The correct UV subdivided in component builder, built with abc, is only available with uv in indexed attrib (htoa).
Can someone explain to me the usefulness of indexed attributes?
thanks
