Hello there! I've been trying your Tools since one or two crashes and I've got some suggestions to include to your promising tool

Here is a galery that illustrates the ideas : http://imgur.com/a/tWcLE

- In the texture settings, put the Filter Size to its minimum (0.10), it avoids getting weird artefacts around the transparent parts (refer to the first and second image in the linked galery,

- Another idea is toggling the Z-Transparency on, to allow transparent parts to overlap opaque ones without having a visual "hole" in the result (refer to the third and fourth pictures)

Thanks for these suggestions! These should be relatively simple to implement.

Out of curiosity, what operating system are you on? I'm wondering if there's some platform differences I do not know about because the textures look okay for me at the current settings. Will still implement these, the changes don't seem to affect the render on Windows.

I'm using Windows (10 to be exact), using Blender's internal renderer.

Ah! Those are renders! My personal use case has been real time rendering all this time so I never thought to actually do a render. Thanks!
