Hi,

I did what you suggested. Erased the pbr plugin and folder from my appdata's plugins folder, restarted everything and installed, following all your suggestions.

Still no good with 1.2.5:

Hi JQL, please follow these new instructions:

1. Close SketchUp if it's open.
2. Open Windows's File Explorer.
3. Go to %APPDATA%\SketchUp\SketchUp 2018\SketchUp\Plugins\pbr
4. Right click on web_server.cmd file. Choose "Edit" in contextual menu.
5. Replace this line:

cd %~dp0 && cd Web Server

by this line:

cd /d "%~dp0%Web Server"

6. "File" > "Save".
7. "File" > "Exit".
8. Open SketchUp.
9. "Extensions" > "Physically-Based Rendering" > "Open Viewport".
10. Do you see SketchUp model in PBR Viewport?

@jql said:

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?

No. Texture is embedded. You must update manually SketchUp material if you change texture on disk.

Linking textures can produce late errors like "missing file". I will think on this.

I'm very happy to announce release of v1.2.5.

Features:

• Control camera with a standard gamepad in Viewport.
  Plug. Move with left stick/pad. Look around with right stick.
  It works with Microsoft Xbox One controller. Tell me if it works with other controllers

• Normal map scale (strength) renders in Viewport.

Bugfixes:

• Fix zoom (wheel) bug in Viewport impacting only Firefox.

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

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

Hi Filibis Thanks for your interest in this plugin.

@filibis said:

But i couldn't operate normal map.

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

@filibis said:

And didn't understand where you put those 2 'base color' textures you provided.

Reef demo model is made of two faces, two materials and three textures:

Sea normal map texture is set on Sea material in PBR Material Editor.
Sea base color texture is set on Sea material in Materials Tray.
Sea material is applied to Sea face.

Undersea base color texture is set on Undersea material in Materials Tray.
Undersea material is applied to Undersea face.

@filibis said:

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.

I see no problem about adding Normal map scale (strength) in PBR Material Editor.

Update: Since PBR plugin v1.2.5, normal map strength is editable and rendered

Metallic and roughness maps must be packed in one map. So it's not easy for user...

Update: Since PBR plugin v1.2.4, metallic-roughness (packed) map is supported

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.

1. Restart computer. Don't open SketchUp for now!
2. Open Windows's File Explorer.
3. Goto %APPDATA%\SketchUp\SketchUp 2018\SketchUp\Plugins
4. Delete pbr.rb file and pbr directory.
5. Download and install SketchUp PBR plugin again.
6. Close SketchUp.
7. Reopen SketchUp.

If problem persists: consider opening an issue here.

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.

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

@jql said:

I have tried the plugin and got the following errors:

Windows can't find 'nginx'...

@samuel_t said:

Is it a first time install or an update?

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?

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

Let me know if problem persists

@jql said:

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.

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 said:

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

Seems a new cool rendering maker!

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.

@nlipovac said:

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

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.

@filibis said:

(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?)

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.

@filibis said:

[...] even though i apply normal map, it doesn't show up in web browser, object looks plain.

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.
