ZDoom

So I recently started GZDoom modding, and have been attempting to create a map with more high-res, realistic looking textures. I wanted to implement some metallic materials, and so I created a test called "shinymetal", but it does not work in the way I want it to. It has no shine and looks like dull rubber, despite me having added the materials to a GLDefs text file with appropriate file structures (or so I believe, I am new but I have done a lot of research on this topic this last week). The image files themselves are in .PNG format, and are held within corresponding folders, such as metallic, ao, normal, etc. A few examples of GLDefs files I have seen are written in different ways, such as the ones on the ZDoom wiki and some examples from .pk3 files I have looked at. I have attempted to imitate a few of them with this material, but so far it has not worked.

I am using the latest GZDoom version, 4.14.2, and while I cannot give the exact specs of my PC I do not feel this is relevant, as I can run other WADs with PBR textures just fine. My GZDoom is also using OpenGl.

Unless someone has an inspired "aha! I know what this is" moment, you'll need to provide more information on exactly how you have set things up. e.g. posting your GLDEFS would be a start.

If you could put together a small test file and upload it to a file host so that people could check it, that would be ideal.

[edit]Thanks for the upload. I don't see anything obviously wrong, but I'm not that familiar with PBR textures. With any luck, someone will come along and be able to shed more light on the problem.[/edit]

Do not include the specular if you're using a PBR workflow. It's either normal/specular for a standard material or normal/ao/roughness/metallic for a PBR material, so that's likely what's breaking it.
