And yeah, alchemist does an Awesome job from what I can tell. The only job left is to make it tileable.
Take a series of images with the light positioned differently, then it spits out the maps for you.
I was just curious if there was something that allowed you to do the same thing. Shoot, it even calculated transparency if you add a light behind the object and include that image. With alchemist you can actually scan something like hammered metal, and it works. The methods of “take a flatly lit picture exactly from the front, then photoshop the hell out of it” is lots of work, and doesn’t work with reflective materials very well. At the time, it was amazing, because that method works even if your object is somewhat reflective. You took the same picture with a light from X, Y, -X, -Y and it created an accurate normal map for you based on that. Nvidia actually had a tool quite a while ago that did something similar.
SUBSTANCE ALCHEMIST LOGO SOFTWARE
The other software I’m finding is just the user guessing, based on a flat lit image. It calculates roughness, metallic, normal map, etc. If you you don’t move the camera, and take the same picture but with light from specific directions, substance alchemist can do Pretty much all the work for you and gives you a fairly accurate result to what you’re actually looking at. It’ll help you generate a normal map, and diffuse, roughness, etc. Most of the PBR material creators I’m finding as “alternatives” are like crazy bump.
