not sure if this is an issue. as per attached image, I just noticed this number Rendering dialog and it seems highly unlikely that my scene has exactly that many faces.
I presume this is just a legacy autodesk display issue and not affecting corona in any way???
Only reason i was even looking was that scene is particularly slow to render.
AFAIK this function is broken sometimes. What nuzmber does corona VFB show? I would guess that the function cannot show anything bigger, so we clamp to MAX_INT
From memory Corona VFB reported around 33 million or so.
Just to be clear, the scene renders correctly, it was just much slower than most scenes at which point I noticed that number.
As per my original post, I am not surprised if it is just a display issue on the built in render dialog (or clamped to MAX_INT as suggested by Ondra)
