[samuel_t]

Hello I'm author of Physically-Based Rendering (PBR) open-source extension for SketchUp.

Features

• Thanks to integrated material editor, enrich SketchUp materials with advanced properties like: metalness, roughness, normal map, height map, etc. What to bring reflections and reliefs to your models!

• Add artificial lights right from SketchUp.

• Visualize enriched SketchUp model in an external window.

• Control scene camera in real-time.

• Save render as a PNG image in two clicks.

• Export enriched SketchUp model to glTF 3D format (Sketchfab...).

License

This extension is open-source and free, including for a professional use in accordance with GPL v3.0.

Funding

If you find this plugin useful, donate at least 1 dollar to support its development. Thank you all!

Download

You will find installation instructions and a download link on the official page of SketchUp PBR plugin.

Demos

See attachments.

Enjoy!

Hi Samuel, interesting plugin, nice to see PBR and Gltf related extensions

But i couldn't operate normal map. And didn't understand where you put those 2 'base color' textures you provided.
Also that would be great if you let normal map strength to be adjusted and option to add metallic & roughness maps as well if possible.

[filibis]

Thanks for the details.

Normal map must be set in PBR Material Editor. Does this info helps you enough?

I know what i meant was even though i apply normal map, it doesn't show up in web browser, object looks plain. (When i launch material editor again right after i applied normal map, it shows blank, does this mean it didn't accept the normal map?) Also i made sure it's 1024px etc.

No. PBR Material Editor doesn't show Normal map again... even if it has been accepted! I planned to change this ergonomic detail because it is confusing.

Update: Since PBR plugin v1.2.0, status of texture image is shown (as checkbox) in PBR Material Editor.

1. Close PBR Viewport (Web browser window).
2. Set then apply Normal map in PBR Material Editor.
3. Reopen PBR Viewport from SketchUp menu.
4. If you still don't see Normal map effect, please report issue here: https://github.com/SamuelTS/SketchUp-PBR-Plugin/issues.

Hi, since this can be prepared for posting on FB, can you make export for *.glb?

Seems I've heard about this new thing somewhere!
Seems a new cool rendering maker!

Hi nlipovac,

PBR plugin only exports to *.gltf. Export to *.glb is not planned.

You can convert *.gltf to *.glb with Make GLB by Saurabh Bhatia.

I must render unto Caesar the things that are Caesar's. Majority of 3D code included in PBR plugin was written by these talented people: Yi Shen and Natty.

I also like this plugin's idea a lot. I'm curious to where it's headed...

A nice feature's coming soon. About camera control... Stay tuned

Version 1.2.4 just released

It's now possible to apply a metallic-roughness map to a material. Demos:

Textures : Free PBR
Renderer : SketchUp PBR plugin

[JQL]

I'd love this if I could eventually link a substance file to a sketchup material...

You can edit a material with PBR plugin then save material as .SKM file.

See this tutorial: https://sketchucation.com/resources/tutorials/528-how-to-create-your-own-sketchup-material-libraries

Thus, it's technically possible to build a SketchUp PBR material library

In other words, .SKM (SketchUp Material) can contain Normal map, etc.

[JQL]

The problem is that a sketchup material hasn't got a direct link to textures residing on disk. So, if I change a texture like color, normal or metal-roughness map, it won't refresh. Or, will it?

[JQL]

I have tried the plugin and got the following errors:

Windows can't find 'nginx'...

I have installed the glTF export (and import) plugins:

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. I can easily create the metallic-roughness maps as I use substance tools, but is there any chance the separated maps could be implemeted?

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.

Is it a first time install or an update?

If it's an update: Open SketchUp Extension Manager. Disable PBR plugin before uninstall it. Reinstall it.

Let me know if problem persists

It's a first time. Pbr v1.2.4

Sketchup 2018

It's a first time. Pbr v1.2.4

Sketchup 2018

Operating system: Windows 10?

1. Open Windows's File Explorer.
2. Goto %APPDATA%\SketchUp\SketchUp 2018\SketchUp\Plugins\pbr\Web Server
3. Do you see the file nginx.exe?

I opened an issue for this: Emissive materials don't glow. It would be great if a GLSL expert could help.

[JQL]

I'm afk today (phone here) but I'm on win10 and I have checked before that the nginx.exe file was there, though I don't know if that was the exact path.
