Does VTT support CVT variations yet? What would happen when the font (main master) is hinted in VTT, but no cvar table is present? Would the values from the CVT table be used for all interpolated instances?

When I was implementing the OTVar export the first examples looked quiet w bit strange because the base font would have some hints and those would keep stems form getting thicker – because I didn’t provide a cvar table. So the the instructions are ''stronger" than the deltas

@Richard Fink In particular - is there any control over the resulting font-weights the type designer must forsake to give the customer the benefits of runtime interpolation? Not 100% sure I understand the question as posed but, with regard to control, any location within the variations design space can contain a delta set for one or more glyphs. So there's no reason for the type designer to 'forsake' control. As an example, a font with a weight axis might contain not only delta sets at the extremes of that weight axis — say, thin and black — but also any number of intermediate delta sets to control regions of the axis between the extremes — say, regular and bold. Again, these intermediate delta sets could cover the whole glyph set, or any subset, or a single glyph. The intermediate masters do not need to sit directly on an axis: in a multi-axis font, a delta set can sit anywhere in the design space between the axes.

I don’t approach interpolation in a systematic manner, I would have to change my method for variable fonts, and make the masters more consistent, and fewer.For instance, in Figgins Standard, I changed the shape of the counter construction between Medium and Bold and between Bold and Extra Bold. Therefore, any layout application interpolation between those weights would be problematic—because of the different number of points, and the design premise that the joint has to be either smooth (“tangent”) or angular.Figgins Standard: Regular, Medium, Bold and Extra Bold.

@Rob McKaughan And the last question is: If I install both a non-variable font and a variable one, what is their application priority? I have a series of non-variable fonts with size-dependent gridfits (to merge strokes under certain physical size), and an unhinted variable one, and I want browsers to use the hinted ones for major styles, while unhinted under other styles.
