"CustomRateMultResource": { /* adjusting the multipliers for a particular item for resource extraction */
        "stones": "3/4",
        "sulfur.ore": "3/4"

I run a server with 10x gathering. I would like to know how I can exclude sulfur from this? I want it to be 1.0 e.g.
Do I add sulfur in this line?
Does 3/4 mean that it is farmed 3/4 of the standard gathering rate like 10x on my server?
How can I set it to 1.0?
Thank you?

Did you read the description of the plugin?

Format for individual items multipliers:"short_prefab_name": "day_multiplier/night_multiplier"where / - separator
Format for individual resource gather tools multipliers:"short_prefab_name": "day_multiplier/night_multiplier"where / - separator​

So, like this:
"sulfur.ore": "1/1"

Thank you for the quick reply. That was really helpful.
