Okay, I'm not sure if the title is quite accurate but I'm having an issue with materials in a blender project I'm working on. I'm working on a model of a truck (as you can guess from the colour it's based on Optimus Prime, it's a private project)
Now the first picture I've got is the model in solid (I use 2 monitors, I don't know how to print screen only one so the left side is BTS of this post)
You can see there is geometry on the surface, such as the bit the spoiler's mounted on, the wheel arches, the frame behind the window etc.
Now this is the the same model in material preview
You can see the probleme, or rather you cannot, all the geometry I previously discussed is impossible to see, for that matter you cannot even see the edges of the shape, if the textures were coloured black it'd look like a silhouette for additional reference here is the Shader Nodes
Please, anyone with suggestions, tell me how to make the materials show the edges.
