</div></div>While we do support them in theory [i64vecN attributes], in practice<br>
they get lowered in init_velement_lowered (ideally attrib->Doubles is<br>
set there). Given that the 64-bit bindless attributes have the same<br>
counting issues, I think they should go through the same lowering<br>
logic, even though in practice it won't matter (since it always fits<br>
into a single attribute).<br>
<br>
I did do a bit of tracing, and it seemed like that should already work<br>
with the current code, but clearly it doesn't for some reason.<br>
<br>
This patch seems like a workaround, although in practice, it will work too.<br></blockquote><div><br></div>Vector uint64 vertex attributes are only supported with the NV extension.</div><div class="gmail_quote"><br></div><div class="gmail_quote">Marek<br></div></div></div>
