Bump Shadow Reverses?
I’m just trying to apply a bump map to a shape. But, half way along the bump, the effect seems to reverse, causing the shadowing to reverse.
How do I do this correctly, or is there a better approach?
Here is the component…

The problem is due to your texture projection. You’re using shrink wrap which is a bit unpredictable. I would change it to flat mapping and then use the texture axis tool to rotate the projection correctly. Then right-click on the tag and select “fit to object”. You’ll also have to change “Side” to both. Alternatively you could use cubic mapping, in which case you can use front side only.
It looks like your phong tag is set too high as well, causing shading errors at the sharp edges. Drop the phong angle to 30 degrees to correct that.

That’ll do it! Thanks Adam!
