Hello! Thank you for your answers!
in fact, most of the time, the "virtual" pass, with "no bloom no glare", is quite satisfactory, same density as the "beauty", but without the bloom effect;
on the other hand, it doesn't work (see examples) it seems to me in general, in large formats; here, the size was 15500 square px; my machine is powerful, with 128 g of ram, the rendering is done without problems, but apparently the virtual pass is affected; it's a pity, because it's precisely in large formats, which "run" all night long, that having the three passes (bloom, beauty, and virtual) is interesting, whereas small formats, rendered in 1 hour, I can do two renders without difficulty!
