Quick question on map formats!

PolycountCounter

Ayyy, just a quick question- I'm in Substance Designer and I'm saving my textures as bitmaps. I was curious what formats work best for the following types of maps-

• Normal maps
• Roughness maps
• Ambient Occlusion (AO) maps
• Specular maps

I've made mistakes in the past saving them as the wrong format, I wanna save them on the right format to get the best possible results.

I save all my textures as tga.

Same thing here, I think it's pretty standard. But if you work in a production, they'll tell you what to use. But yeah, use tga.
