Bump Outline

I feel like I should know what’s happening here, but I can’t get it :confused:

I’m creating a boot print by enabling the “Normal” in the “Influence” panel, but I get this bump outline around where the texture image bounds are.

I’ve tried using a texture with alpha and just black and white but I always get this outline. Where’s the magic button? :slight_smile: Thx!

Under image mapping > Extension I had it set to “Clip” , Setting to “Extend” fixed it.

Premultiply? RGB to Intensity? Oh nice. nevermind
