Questions about PBR texture
Hi guys sorry if this is a beginner question. I recently just started learning about PBR texture such as: Albedo, roughness map etc. My question is, how can I create those textures? Can I create PBR textures with software such as Gimp or Blender? Or do I have to purchase those advanced software like Ddo suites? I did some research online, I couldn't find any tutorial about creating them, I'd be very appreciate if any one can tell me more about the PBR textures. Thank you!
You can absolutely do it all by hand, using Photoshop or Gimp. For example if you wanted to create some cracked earth, you'd go online and find a nice flat looking texture of cracked earth.
Open it in Photoshop/Gimp, crop it to a square and tweak it to be repeatable both X and Y.
From there duplicate your texture layer and try to produce a height map, starting from a grayscale version of your texture.
Using this online tool (which does a decent job) http://cpetry.github.io/NormalMap-Online/ you can generate your online maps.
Then for your roughness you can use your heightmap (probably inverted and tweaked) or a completely different texture (scuffs marks etc. black and white).
At that point you will have most things required to get a decent PBR material.
Other software that could help though are CrazyBump and xNormal.
