Guide specular map test:
hey man, you also need to replace the texture on all the myteam[engine] erp as they are using the same mipmaps. The reason why its blurred is the game is using the texture inside the erps that is not change and they are the low quality one. Ahh! Okay thank you. Man, learning a ton here and...

Thanks mate, I did see that post but I guess I assumed it was more difficult than that. Actually it is more difficult than that, through some trial and error I think I have a decent spec overlay.
I should mention that I finally updated the specular post I made earlier in the thread (that Samideluxe linked). I left everything I had before, but added what settings to save the Specular map as, and also what the colors that Codemasters use for their spec maps:

Thanks, that's a good reference.
I ended up with a nice metallic effect from a blue #0080ff. Reminds me of what Jaguar did a few years back. Looks great especially contrasted against matt or gloss #ff3500 (the yellow below is gloss).
I exported the specular layer same way I did the main livery (BC7) and it seemed to work, should I redo it as BC1?
Next question:
I'm trying to modify my car number to match the livery but can't quite figure out how to save it in photoshop. You can see in the image above the background isn't completely transparent. Anyone got a quick step-by-step on editing car number files?
EDIT: Well I figured out how to get the transperant alpha channel saved, but now the colours are wrong.
Here is what I did.
Export the texture using ERP Archiever
Open in Photoshop with alpha channel (not with mipmaps as separate layers)
Edit colours as desired. I assume if you want to edit the shape (I did not) you will need to adjust the alpha layer to match.
Save as Intel DDS and chose color+alpha, it set BC3 automatically, mipmaps auto generate.
Import using ERP Archiever for desired car.
I wonder if BC3 was the problem?
Not happy with the colour compared to how I set it in Photoshop (same green as the car).
EDIT 2: Yup, BC3 was not the right setting. BC7 SRGB Fine worked great (same as the main livery).
BTW the reason the highlights look blown out is because the screenshots were taken in HDR (as EXR files) and then brightness/exposure adjusted back down to save as JPGs. The metalic sheen of the green paint looks amazing in HDR.
