Custom fonts not working with SheetRenderer- but work with PDF

I’m trying to get a custom font to work, I loaded it into CellsHelper.FontDir, but when I render a sheet with SheetRender.ToImage or ToTiFF it defaults back to Calibri. When I Save the same workbook as PDF it renders with the correct font.

Does SheetRender use the CellsHelper custom fonts when rendering cells?
I turned on the warning callback and it’s not saying anything about font substitution.
If I don’t set the FontDir it gives a warning like:
Font substitution: Font [ Whitney Semibold; Regular ] has been substituted in Cell [ B22 ] in Sheet [ Chart ]

So I’m pretty sure SheetRender is doing something with the CellsHelper custom fonts…it’s just not actually rendering with them? Even though save to PDF does? Is there some other trick?
