You have a few options for this:
You can download this template filter that was created in the Web Studio, load it in the studio, and change the LUT via the option in properties. If you want a custom one instead of the samples we provice, you will need to follow the guide on How to make a LUT.
You can download the template filter from point 2, unzip it, go into /TemplateLUTFilter/color/ and change the file provided for one you have create via the How to make a LUT guide directly, and then modifying the config.json of the filter to change line 428 (by default:
“file_name”: “color/bnb_template_lut.png”,) to contain the correct name for your new LUT file.
