Scaling/Tuning Weight

I recently purchased the RMX Tool.
When I’m working with the Scaler (or Tuner) and try to change the
weight, there’s nothing happening. (height, width does respond)
What am I missing?

As always thanks a lot everyone

Have you read this: RMX Scaler without multiple masters?

Hi, as Georg linked your previous post, I assume you’re still working with a font file that only has one weight master. In order to create different widths and weights, you need to have two masters between which you can interpolate. Are you familiar with the concept of interpolation?

Even when you have masters, the outlines must already be different- again, because otherwise you trying to interpolate between two identical shapes. I confess I spent ‘some’ minutes learning this. :joy::joy::joy:
