[Plugin] Physically-Based Rendering - v1.5.9 - 19 Apr. 2020

samuel_t

Overlay feature request is out of my skills for now. Maybe another dev can, since code is open-source.

samuel_t

Thank you for your idea.

JQL

I will talk about this case with someone...

Thea has viewport rendering which, for single monitors brings sketchup to life. Your plugin, as it is realtime, would be amazing with viewport rendering.

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.

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!

You are right. I forgot to mention this case.

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

@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:

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".

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.
