Hello! I'm very new to ccing, this is my first project and I'm attempting to troubleshoot a simple issue of my wall sculpture object having a very dark shading issue. I've posted a link to a short video showing how the object looks in S4S and in the game as well as some photo links below. I'm using version 3.1.5.2 of S4S, and I used Blender 2.8 to model, importing to 2.7 for UV mapping and baking.

As you can see the fan object looks very dark in the game. I've tried all of these links for help, but I'm afraid it didn't solve my issue:

I'm more than happy to provide my .package file, but I'm unsure of how to do it on the forum site, as I'm unfamiliar with it. Please let me know what I could have missed or possibly done wrong! I really want to learn to do this correctly so I may be able to create more CC for the community.

Thank you so much for replying!

So I did end up just doing it again with a different object and it seemed to work better, but I still need to know what I did wrong on the first one. The first one I used the Cork Board object, the second one I used the Sun Wall sculpture object. I think it may be something to do with the bump and spec maps, but I'm genuinely not sure.

Edit: Well nevermind, the second one doesn't work at all now.

When you say it has a dark shading issue, are you talking about the shadow that's cast on the wall? Or something else? What exactly is the problem?

The reason I ask is because, if it's the shadow that the object is casting that's the problem, you could change the SSAO settings or uncheck the shadow caster box. I can show you how to make those changes. If the object itself is too dark, the answer would be something different.

Edit: There's a sticky post at the top of this forum that lists common problems. Nobody ever bothers to check this first when there's a problem (including me, at times) but it covers edge splitting.

The object itself is very dark, even if I mess around with the bump and specular images. The object shadow is perfect. The object looks dramatically different shading-wise in S4S, like a normal one would look. However in game it darkens and changes hue considerably. Other CC and vanilla objects don't do this.

Yeah it's not edge split. Does edge splitting fix the darkness? (open the mesh in blender > in object mode select s4studio_mesh_1 > modifiers (blue wrench) > edge split > apply)

THAT WAS IT, thank you so much! I never saw this in any of the tutorials I've followed, how does edge splitting fix the issue exactly? Does this need to always be applied, or only on some objects? Do I need to do this for the shadow mesh as well?

When you have faces that are turned 90 degrees from the other faces they're connected to, Blender doesn't know how to apply light to them. When I say 90 degrees, think of the letter L. See how one line goes up and down, and the other goes back and forth? That's what I mean. If faces are connected like that Blender gets confused. The solution is to disconnect the faces at the edge where they meet so Blender knows to apply light to them separately.

It's always worth running edge split on a mesh once you've finished making it. Basically the weird shadows come from the game/blender trying to shade multiple faces as a continuous face. This means that small angles (like on a cylinder) are shaded smoothly, but it looks odd on anything that's meant to be two faces. Edge splitting tells the game/blender to shade them separately.

And no, you don't need to do the same to the shadow mesh, since that just defines where ssao shadows go (those dark blurry lines around an object) and what shape direct shadows are
