Adjust Regular instance weight in Inter 4?

[ahmadfawaid]

Hi! I’m tweaking some weights and characters of Inter 4 for a design project I’m working on.

I managed to adjust the font weights, but I’m stuck on one thing—changing the weight of the Regular instance. The Regular master is set to 400, and when I try setting the weight to 430 or 450 in Exports, I keep getting errors. I want it slightly bolder.

If anyone knows how to do this, I’d love some advice!

Thanks a lot!
