Hi!
I saw your textures and must ask about workflow you use to create them.
I'm new to blender and tried a bunch of things recently, but can not get that feeling.

I would really appreciate your help in any amounts!

hey
i used cinema4d + substance painter and finalized everything in photoshop
the materials i used were basically the simplest ones
honestly it doesnt really matter much if you do it in blender or anywhere else

what i can recommend is digging into how PBR materials work

anyway theres a whole dump of all the 3d source files on the mods github

just remembered a few interesting things
- for factorio you should render sprites at x4 the normal size and then downscale them with "bicubic sharper" otherwise everything gets blurry
- the camera is at 45 degrees and the sun is at 45 too
- and the fun one - i found a trick with perspective
