I forked and updated the script a bit: https://gist.github.com/aidv/05779c76401ae55ee6b227ee0c1e47f9

Apparently AMD GPU's are very wonky with COLMAP/GLOMAP, so forcing CPU usage is better.

This is so good!! Thank you

I ported to PowerShell because I having problem running with cmd on my PC

I had to add a few lines to make the bat work for me... Hoping to save someone some time:

I had to add COLMAPS dll folder to PATH (Add after set "SCENES_DIR=%TOP%\04 SCENES")

:: ---------- Put COLMAP’s dll folder(s) on PATH -------------------
set "PATH=%SFM_DIR%;%SFM_DIR%\bin;%PATH%"

And QT would return errors if I did not define the plugin folder...

:: ---------- Tell Qt where its plugins live -----------------------
set "QT_QPA_PLATFORM_PLUGIN_PATH=%SFM_DIR%\plugins\platforms"
set "QT_PLUGIN_PATH=%SFM_DIR%\plugins"

Lastly, the UTF-8 symbols wouldn't display correctly. (Add after @echo off)

rem Force UTF-8 so Unicode symbols display correctly
chcp 65001 >nul

can you make a new version so its works with new colmap and glomap and new blender version.please

I made a docker based solution for the pipeline mainly for my mac that builds GLOMAP and COLMAP from source. Repo here.

If your computer is not in English you might run into the trouble of the bat file not working like me (My PC is Japanese, cmd appears for a second and crashes). What worked for me is to open the bat file in windows own basic notepad (not notepad++) and save the file again in ANSI (the drop down menu is at the bottom right corner of the 'save as' window).

Here is the step by step:
The Fix: Save as ANSI/Plain UTF-8

1. Open the standard Windows Notepad app.
2. Copy the original batch script text from your very first message and paste it into the blank Notepad window.
3. Click File > Save As...
4. Set the "Save as type" dropdown to All Files (.).
5. The Most Important Step: Look at the Encoding dropdown at the very bottom of the Save window. Change it to ANSI (If ANSI isn't available, select plain UTF-8, but strictly avoid "UTF-8 with BOM" or "UTF-16 LE").
6. Click Save (overwrite your old file if necessary).
7. Run the bat file again.
