Hey all. Having some issues with imgui_add_ttf_from_file. Trying to use the previously provided examples in the demo but the font either doesn't change or causes an immediate crash. Before the imgui_begin function I am defining;

ImFont *ImFont01 = imgui_add_ttf_from_file("c:\\Windows\\Fonts\\FuturBlock-Regular.ttf", 18, GLYPH_RANGE_Default);

Then in the function I am calling it as;

imgui_push_font(ImFont01);
imgui_text("Test\r\n");
imgui_pop_font();

Any idea on what I am doing wrong?
