Is this the direct copy of your script? If so, I copied that to Notepad++ and there are unnecessary spaces.
It seems like your script doesn’t run at all (as you are getting empty files). Can you try to add “^” sign after each of your command?
Also, just to check the script, run it not as headless (unless until it will run properly).
Which version of RealityCapture are you using? If it is up to 1.4, you don’t need to use -activate command.
In -writeProgress command you are missing the file name (-writeProgress “C:\CalculateTextured3DModel\log\log.txt”).
