    This is the most misunderstood procedure. The manual explains that the speed is set by a combination of the magnet’s vertical position and its rotational angle relative to the stepped pulley.

      Some time ago I had a unity pro license and tried to use Unity’s Success Advisors service but couldn’t find good information about this. Could you share some info about this service?

        Unity’s FAQ’s suggest that you should have received an email from a Success Advisor shortly after purchasing Pro, with details on how to contact them. As for what a Success Advisor can actually do for you, my understanding is that the role, as far as Unity is concerned, is as a point of contact, basically to help you navigate Unity’s services or, possibly, to match you with learning events that you might need. While this might be useful if you don’t know what Unity can offer you, I don’t believe that it’s a technical or developmental support role and it’s likely that your advisor will be there to match you with Unity’s products more than they will be there to help your game succeed. However, I may be wrong, I don’t have direct experience with this service but I’d love to hear from someone who has.

      Thanks John, Great article. How about the Pro’s line item of “Over 300 hours of professional training content available”. Is that a worthwhile benefit of the Pro’s plan?

      Thanks,
      Tim

        Hi Tim, while I haven’t confirmed it, I believe that may be referring to Unity Learn premium, which became free for everyone in 2020 (see this blog post for details). As far as I can tell, there’s no other mention that Unity Pro customers get premium learning resources that other users don’t. Additionally, one of Unity’s biggest benefits is that it’s extremely well supported by community tutorials and resources that are either free or low-cost, at least in comparison to the Unity Pro price tag.

          After getting in touch with Unity, they’ve told me that refers to Unity Learn, which I believe used to be a Pro perk but is now free for everyone.
