Isn't SHOP obsolete in favor of /mat? So I suppose SideFX won't be adding more support for SHOP?
Yes, shops are obsolete. Don't use SHOPs except for legacy mantra or 3rd party renderer materials.

The usduvtexture is missing a usdprimvarreader connected to the st input for reading the texture coordinates.

The geometry color shows whether or not I enable materials. I don't have the ability to enable High Quality Lighting mode though.

See the attachment. I selected "grid", Scene Graph Tree shows that it's been selected, but network view just doesn't care. Is there a way to make network view jump to the selected object?
Nodes and scene graph objects are not explicitly interrelated the way object nodes are related to objects in the scene view. A lop graph is more like a sop network in that sense. A sop might create a sphere, and later ones move some verts and maybe add some particles. Selecting the sphere's geometry has no connection to the node that made it. The selection only represents the elements that are a result of the previous operations.
Prims created by nodes do however store metadata linking them to the creator node. This allows the rightclick->Edit Primitive menu to present the option to jump to the node that created it. I don't think there's an option to automatically jump to a particular node that touched prim on selection, but I can see how that can be problematic, as it's ambiguous which node to edit by the nature of layered edits.

This is working fine for me in houdini 19.0.444. Are you sure you're connecting the correct primvar to Opacity? If the attribute was 'Alpha' in SOPs, it will be renamed 'displayOpacity' on import to solaris, unless this option is disabled.

Thank you very much. The weird thing is that sometimes these layer color codes change themselves after I close/re-open Houdini. Is it normal? I found it extremely confusing...
It's assured that I did absolutely nothing between picture 1 and picture 2, except re-open Houdini.
They're the same though. The same run of nodes edit the same layer and share the same color.

I very quickly tried this with the Beach Tank shelf tool and also got the same behaviour.
Interesting. It looks like there's a conflict for the name "render". The whitewater_import node ends with a "render" SOP and ends up generating render.usd ... then the "main" USD ends up as "render2.usd". If you rename the SOP in the whitewater_import to "render_null" (or anything different) then "render.usd" will be used for the "main" USD again (with the camera).
I'll look into a better fix, but hopefully this keeps your project moving forward for the time being!

why do the layers from the usdrender node endup in a flattened folder structure instead of in node paths, i.e. {usdroot}/obj/geo1/sopname.usd
this is how they write out of the usd rop.

The syntax error is from the backticks around the expression. These are only for evaluating expressions as literals in string parameters. Numeric parameters always evaluate expressions because the expression is always a keyframe.

Hi @Brad - I think you need to ensure that karma/husk can find the HDA when it starts up. I think there are a few ways to do this. One way is to ensure the .hda with the shader is installed in the HOUDINI_OTL_PATH (i.e. $HOME/houdini19.0/otls/lens_shader.hda).
Do CVEX shader builder vops work with Karma/husk as lens shaders?

In my case I attempt to write diffuseColor as a primvar but can't seem to get this picked up by a usdpreviewsurface.
Usdpreviewsurface doesn't pick up primvars, usdprimvarreader does. This is not a bug.
