I've met two issues importing from SOP to Solaris:
- viewport doesn't seem to always update auomatically, when normals change, but there is a workaround - restarting viewport.
- broken normals in viewport when using SOP Character Import. Couldn't find a workaround for this
I'll attach steps to reproduce the issues below. Did anyone met those issues too when working with Solaris? Is there some way to make viewport update automatically for first issue and resolve normals for the second one?
Steps to reproduce the issues:
I. Viewport doesn't update:
1) Let's add SOP Create with just a Cube inside. Unlike the viewing the SOP node, viewing this cube from Solaris node looks ugly. And normals are also broken, if we export USD and import it somewhere.
2) Adding normal doesn't seem to fix the problem, at least if we're looking at viewport.
3) But recreating viewport helps - so adding normal does help, but viewport doesn't update for some reason.
II. Broken normals when using SOP Character Import.
1. Create a setup like so. All nodes have just default values, except Rig Doctor needs Initialize Transforms checked.
Importing this USD somewhere else is broken of course too:
2. Let's remove bypass flag from Normal node and restart viewport - normals appear still broken.
But if we open exported USD in some other program, it appears okay. So it's some kind of Houdini viewport problem.
