1. Substance Designer always exporting terribly noisy normal maps?

   Hey, Polycount So I ran into an issue which I haven't really encountered or noticed before - any normal map that I export from SD ends up having lots of noise, unless I export pure normal color, or so it seems. Even when I fill the noisy areas with pure normal color, it doesnt actually remove the noise, it just reduces it.…

   Also, it seems that SD node previews dont have any noise, only exports, including both png and tga.

   tga doesn't do 16 bit so it's probably dithering the output - there may be an option for disabling the dither(not sure, haven't used TGA since about 2011). if you're exporting 8bit png the same is probably true

   Okay, so a little update, exporting as PSD gets rid of all the noise. Thing is that at the very least, I never noticed that either tga or png have this much noise in what are supposed to be blocks of solid color, not even gradients. Is it expected from such formats? I always assumed that at least tga is lossless.
