Also, I found you removed support for emissive materials, which would be a shame, as I use them for all my lighting applications in Thea for Sketchup and would find them cool to test on this pbr plugin.
Today, I think it's better to implement glTF KHR_lights extension. So PBR plugin users could:
- Add and place lights in SketchUp (Maybe as hidden geometry? I'm looking for solutions.),
- Set light type (point, spot, etc.) and properties (color, intensity, etc.) again in SketchUp,
- Export lights (embedded in glTF file) to PBR Viewport and possibly to other platforms...

It's easier for most users to have a separated roughness and metallic maps as they are very common, instead of the metallic-roughness map required by the plugin. [...] is there any chance the separated maps could be implemeted?
~~I agree it's easier but it's not so much long to pack metallic and roughness maps in third-party software. For example, it takes less than one minute in Photoshop following these instructions:
- Open roughness map in Photoshop.
- Convert Grayscale to RGB Color.
- Unlock (roughness) layer.
- Select (roughness) layer. Open Blending options.
- Uncheck all Channels except G(reen).
- Place Embedded... metallic map.
- Select metallic layer. Open Blending options.
- Uncheck all Channels except B(lue).
- Save as... metallic-roughness map.~~
Update: Since PBR plugin v1.3.0, Metallic and Roughness maps are separated in PBR Material Editor.

Good news indeed. Will try it again.
-
Good news! PBR plugin becomes really handy with the new version (1.3.0).
Features
- Change environment map from SketchUp "Extensions" menu.
Tip : Changing environment map changes ambient light map. - Metallic & Roughness maps are separated in Material Editor.
- Access online help document translated in FR from Viewport.
Bugfixes
- Fixes pan (middle button) control issue in Viewport on Firefox.
- Fixes a little gamepad control bug. Improves maybe performance.
As part of an update, remember to disable plugin before uninstalling-reinstalling it. - Change environment map from SketchUp "Extensions" menu.
-
Next PBR plugin version will include a (micro) library of royalty-free PBR materials.
These will be available in "Materials" tray. Render-example with "Wooden Palisade 01":
This should allow new users of plugin to become familiar with PBR materials.

Hi, I have one question.
What is stopping you in developing this plugin as synced rendering plugin for Sketchup (or maybe as an overlay to SU window)? Is this far-fetched for me to think like this? -

That implies using internal browser but external browser is more up-to-date. -
Thea has viewport rendering which, for single monitors brings sketchup to life. Your plugin, as it is realtime, would be amazing with viewport rendering.
-
Right like that JQL, I am quite impressed by this plugin and like to Blender is Eevee this would be a great plugin for SU if it would be implemented as an overlay to SU.

By "overlay", you mean a top window a bit like PBR Material Editor? Fullscreen or splitscreen?
-
This is Thea rendering in SU window, the same thing Vray have also.
-
-
It was just an idea, thank you for this that you already accomplished with this plugin.
-
Overlay feature request is out of my skills for now. Maybe another dev can, since code is open-source.
-
Thank you for your idea.
-
I will talk about this case with someone...

Yeah. There is an expensive workaround: to buy several monitors.
More seriously, I will try to find a way to synchronize PBR Viewport with SketchUp. -

- Plugin comes with a tiny PBR materials library. Donate to make it grow!
Take a look at these websites for free (CC0) textures: Pixel-Furnace, CC0Textures, freepbr. You can provide link to these sites maybe?
I think you should indicate that we need to open a collection to use PBR materials you provided. People may not find PBR folder you generated easily.
In addition to 'saving, opening and creating' a model, when we "apply all changes" in the PBR material editor, Chromium pops-up and updates the view as well.
HDR images working fine
Can we rotate them somehow? That would be cool

Hello filibis, thanks a lot for these links.

I added following sentence in official README:
Additionally, you should have a new "PBR" materials collection in "Materials" tray. Enjoy!@filibis said:

You are right. I forgot to mention this case.

@samuel_t said:

Yes. Rotating the HDRi 360° will change the lighting directions since HDRis gather light intensity from the brightness of pixel colours. Thus normal maps will behave accordingly.
Something like this:
Or simply to change background view:
