Issues when baking mesh in Substance Painter

Hi. I feel like I should start by saying that the tutorial you’re watching is teaching you wrong things. Instead of telling a beginner to get two additional paid programs to sculpt wrinkles, retopologize and bake textures, they should be teaching a). how to sew a garment in a way that it does not stretch when cut or for wrinkles to appear automatically where they should be, b). how to make it look smooth (the avatar should be subdivided before you simulate the garment), c). how to bake textures in blender.

But to answer your question. If you’re certain that you baked shading from high poly to low poly correctly, then it’s just a matter of depth. These details aren’t deep enough to make a significant difference on the diffuse map.
Try baking a normal map, that’s where these differences come through. If you still won’t see anything, you may be doing something wrong. Look up this exact process (baking from high poly to low poly in substance painter) on YouTube, just in case something is missing
