Unable to change fluid world units


I watched a tutorial that made use of the fluid simulation -> domain -> world -> size units option. But I’m unable to change these units. It’s greyed out and I can’t change it from use scene size units to a custom value…

Where can I unlock that feature?

Thank you…

What tutorial ?
Please attach screenshot and post a link to your blend file

Did you change your scene units to Metric? :slight_smile:
That greys out the option for world size. Just put it back to the default and all will be well.

Tutorial is this one: http://vimeo.com/31832546 about min 14.

That’s it. Changing the scene units from metric to none does the job! Thank you NicebergStudios!

You are very welcome! :wink:
