Hi there,
for a shader i would like to use a list of floats from a .txt file.
It works all well with a Parameter set to String.
But not when i want to use a .txt file with the same text(values) in it.

Is there a special .txt format?

Any tips are welcome!

thx

A “File String” parameter won't return the content of the file when you evaluate it. It will return you the string path to the file.

There doesn't seem to be an easy way to read file content from vex. You'll have to add another string parameter and put a python expression on it. In the expression, evaluate the string path, open and read the file in python with it.

This is where systemRAW can be used.

On Linux,
`systemRAW(“cat myfile.txt”)`

Please tell us how you managed to get it working as you won't be the last one to ask how to read file content in vex.
