Reality Composer Pro node previews?

I have been digging into learning shader graphs by watching Unity shader graph content, cause lots of the same concepts apply.

One thing I noticed was that in Unity, each node in the shader graph has a little preview. I don't think this exists in Reality Composer Pro, but is there anyway to mimic it (like can I hook up a node that allows me to debug the graph at that point?)

If not, I'm happy to just file a feedback about it, but just thought I'd ask!

Coming from unity, this feature would be insanely helpful

I haven't found a feature that does what you ask, but as a workaround, you can add a separate PreviewSurface node just for previewing. When you want to preview a node, connect it up to the appropriate input of the PreviewSurface node, and temporarily connect the Preview Surface node to the Custom Surface output of your material.

Note that this has two major downsides:

It requires some fiddly manual connection. It would be so nice if this were automatic!
If the type of the node you want to preview doesn't match the Diffuse Color input (or whichever input you want to use) of the PreviewSurface node, you'll need to transform it into color data first, which adds more tedious steps.

I'd definitely recommend filing a feedback explaining why you'd like this, and how you use it in Unity! I find myself missing the same feature from Blender's node tools add-on.
