Border around all decals

[Master-J]

This weird border is caused by aliasing and can't directly be removed. I already implemented a workaround to this which consists in using a texture mask with transparent borders to hide this aliasing.

There's a mask available in the src folder of the addon (decalco/src/alpha_mask.png), all you need to do is assign it to the bordel_mask texture field in your material's settings.

I have that applied, it doesn't seem to make a difference though. Turning off mipmaps in the import settings makes the line go away, but I'm not sure that's a good solution.

Mipmapping doesn't seem to be related to the issue (just tested on my workstation and it works in both cases).

This could be related to you render resolution or an issue with your graphics driver.

If disabling mipmapping solves the issue, you can go that way, just keep in mind that the texture will always keep its higher level of details at any distance from the camera. If it's an issue, you may want to implement some sort of culling on the decals.
