Hey, think I found a bug with the Text POP’s GlyphId attribute (build 2025.33230).
With the text set to aa bb cc, POP to DAT shows GlyphId values like 1052841984, 1049686016, 0 over and over. Those look like floats read as ints (~0.38, ~0.28, 0), probably position data.
With aa b the viewer shows 0 for all prims, but the labels for the b end up somewhere below and left of the text instead of on the letter.
GlyphIndex and CpIndex seem fine. What is GlyphId supposed to be, the font’s glyph ID? None of these attributes are on the wiki page yet.
