Hi all.
I am getting some mantra error like this:
mantra: Singular matrix detected “/obj/Window3/WindowSmoke”
…
And so on.
Anybody knows why is it happening?
Th object only contains a particle system without any geo copied or instanced to the particles.
I am not using motion blur.

Do you have some particles which have a zero size? If so, there's a zero scale and you end up with a singular matrix (non-invertable). Mantra won't render these particles and is warning you about it. However, this is probably what you want, and so the warning can probably be ignored.
