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.

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.

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

It is not a Houdini issue. I believe it is a Maya issue.
I exported a usd file from Houdini to Maya and Blender. This is the result.
I guess it's because Maya cannot read usd file correctly, however even blender can.
Maya USD sucks.
If I remember correctly your orientation on the mesh needs to be right handed for Maya to read it correctly.
