Regarding future development, LOTT requires two long-overdue updates to maintain full compatibility with the current workflow:

1. Integration of new native tools: Several recent SketchUp tools are currently missing from the LOTT catalog and must be added.
2. Iconography update: The UI icons need to be refreshed to align with the current SketchUp environment.

Again, thank you!

To understand and reproduce the issue:

1. Install the free D5 LiveSync plugin for SketchUp.
2. It generates a folder named d5_converter inside the SketchUp Plugins directory.
3. Start SketchUp.
4. LOTT scans the Plugins directory, encounters the d5_converter folder, and attempts to open it as a file.
5. This triggers the fatal Errno::EISDIR exception in lordofthetoolbarsmanager.rbe (ghost_command_register).

The script requires a bypass condition (e.g., next if File.directory?(path)) when reading the plugin directory contents.

• D5 Render : https://www.d5render.com/download
• D5 LiveSync for SketchUp : https://www.d5render.com/livesync/sketchup

I don't have D5 installed and I don't really understand why it creates problems with LOTT.

Hi Fredo,

The last update doesn't fix the D5 issue. Either way, we can only use one of them (LOTT or D5 Render). So now my entire workflow is blocked, and so is the workflow of other D5 and LOTT users. We really need a QUICK fix for this, please.

I am reporting a fatal initialization crash occurring on SketchUp 2026.1.2 when using the latest D5 Render LiveSync plugin alongside Lord of the Toolbars (v3.0a) and LibFredo6 (v15.9c).

The Master Toolbar (yellow wheels) becomes completely unresponsive, and all custom toolbars disappear from the screen.

The Ruby Console highlights an unhandled directory scanning error in lordofthetoolbarsmanager.rbe inside the ghost_command_register method. It appears the script tries to open a sub-directory as a file, throwing an Errno::EISDIR exception.

The main folder causing the issue is d5_converter, located at:
%AppData%\Roaming\SketchUp\SketchUp 2026\SketchUp\Plugins\d5_converter

Exact stack trace:

Temporary Workaround found:
Renaming the d5_converter folder to _d5_converter allows LOTT to load correctly, but it completely breaks the D5 LiveSync connection. Downgrading D5 LiveSync to v1.6 also works.

It seems a simple check to skip directories (like File.directory?) during the ghost_command_register file loop would prevent this crash.

Thank you for your work!

Anyway, the trouble might be in the habitat_site_context.rb script, as shown in the Sketchup startup error box..

Did you get an error with the previous version of LOTT and this script installed?

Isn't Lord Of The Toolbars free??

Moderators are holding my postings for FOUR DAYS before putting them up here!

When you pay money for a product, I consider this lousy service! I know developers are busy, and I'd be quite forgiving, but demanding FOUR DAYS before a developer can even see my answer to their question is insane!

Requirements

• LibFredo6: v15.9b or above
• Sketchup version: SU2017 and above

LordOfTheToolbars 3.0a is a maintenance release including:

• Bug fixing
• Future compatibility

Home Page of LordOfTheToolbars for information and Download.

Main post of this LordOfTheToolbars thread.

Could you tell me what is the name of the main folder of the D5 extension. I don't have it.

Then I can exclude it from LOTT.

Hi,

For some reason while trying to set up my toolbars, my V-Ray tool sets do not show up in the Master Toolbar Manager. It seems like almost everything except that shows up.

Is there something specific I need to do to get it to show?

Thank you!

Nothing you can do. I had to remove VRay from the list of icons because VRay does something to precisely avoid indirect calls (liek LOTT does).
