I'm using Blender 2.76b with the internal renderer. Whenever I render a simple plane with a texture applied to it, I get a small border on the edges that consists of a mix of the expected texture color and the color on the opposite end of the texture. The same thing happens when using the add-on called "Import Images as Planes".
The texture settings I've tried so far:
- Enabling and disabling repeat
- Disabling Mip Map
- Disabling Interpolation
- Different filter types
- Filter Size 0.10
- Enabling Minimum Filter Size
The filter size seems to have the biggest impact but even the lowest possible value doesn't get rid of it entirely. See the example on the lower left for best visibility:
One way I could think of to fix it would be to add some empty space around the texture image. But since I'll be using my objects outside of Blender and I haven't encountered this elsewhere, I'm a bit hesitant about the wasted texture space. Is there any other way to fix this?
