Take a look at these websites for free (CC0) textures: Pixel-Furnace, CC0Textures, freepbr. You can provide link to these sites maybe?

Hello filibis, thanks a lot for these links.

@filibis said:

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.

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

@filibis said:

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.

You are right. I forgot to mention this case.

@filibis said:

HDR images working fine Can we rotate them somehow? That would be cool

I don't understand. You want to rotate HDRi?

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:

I understand now. Thanks for the trick!

A new version is available, 1.3.2.

Add macOS support. Test n' report.
Add 2 new materials in PBR library.

samuel_t

A new version is available, 1.3.3.

Add exposure control in Viewport.

Exposure

Add one material to "PBR" library.
Disable Viewport update on save.
It was too slow. I recommend to set a shortcut for menu entry "Force Viewport Update".

Shortcut

Hi, I really want to test this plugin but when I install the plugin (or after restarting SU) I get the message that Chromium cannot be found "Get latest". I'm working on a Mac. I can change materials but force viewport update crashed SU. I'm also not sure how I can start a render? Is that the force viewport update or am I missing something. The help page on github is not really helping as well.

I hope you can help/fix. The plugin looks promissing! Thanks!

Best,
Peter

Hi Peter,

Viewport use Chromium. Viewport opens automatically.
I don't have a Mac, this is why its support may be buggy.

It seems you have a problem related to path or chmod.
Please open Ruby Console in SketchUp and paste this:

PBR;;Chromium.executable

Then give me back console answer with a screenshot.

Thanks!

Hello. PBR plugin version 1.3.1 is available.

What's new?

Plugin comes with a tiny PBR materials library. Donate to make it grow!
When you ~~save,~~ open or create a model: Viewport is automatically updated.
Technically, nginx Web server has been replaced by Chromium Web browser.

As part of an update, remember to disable plugin before uninstalling-reinstalling it.

samuel_t

The new PBR plugin version (1.3.4) :

Keeps camera position in Viewport.
Increases material library to 9 elem.
Fixes an exposure issue in Viewport.

Hi Samuel,

I get this:

PBR::Chromium.executable
/Users/peter/Library/Application Support/SketchUp 2018/SketchUp/Plugins/pbr/Chromium/Mac/Chromium.app/Contents/MacOS/Chromium

I can get inside the plugin folder and find the chromium app but I can't start it. All priviliges are correct for the files read and write are set for all files within the pbr folder. Maybe if I replace the Chromium app with a newer one from the internet it works? I will try today.

Thanks!

Best,
Peter

Edit: OK, after replacing the chromium app with the latest from chromium.org the viewport is working!

Hello Peter,

File: exists. Read/Write: granted. OK. Now...

Open a Terminal in OS this time and paste this:

chmod +x '/Users/peter/Library/Application Support/SketchUp 2018/SketchUp/Plugins/pbr/Chromium/Mac/Chromium.app/Contents/MacOS/Chromium'

It should make Chromium file executable.

Best regards,

I added a Workflow section in GitHub README: https://github.com/SamuelTS/SketchUp-PBR-Plugin#workflow

Next PBR plugin version will include latest Chromium macOS stable version.

So I played around with it a bit. A couple of things I noticed. The suns position doesn't get exported and the UVs aren't coming through correct.
I've added a screenshot. The house is exploded (was a component) but that didn't help.
It looks promising!

Best,
Peter

This is a known issue and there is a workaround.

Texture looks weird with perpendicular lines around.

With your preferred photo editing software, resize texture image to a power of 2 in height and width (e.g. 1024x2048, 2048x2048, 4096x4096). Reimport texture image in SketchUp.

Ah thank you! I should've read the documentation better...
I will try it again.
