Some time ago I was creating some vines for a mod. The leaves were 6 quads mapped with a photo of a leaf. The area beyond the periphery of the leaf was transparent.
Everything worked as expected. I highlighted ZTransp, set A in the material panel to 0.00, and ticked Alpha in the Map To panel. The export (to a .nif file) correctly showed the leaves with the portions of the meshes beyond the edges of the leaves as transparent. Of course, Blender’s 3D view, with Draw type set to Textured, didn’t show the transparency (see attached image 1).
However, one day I did something and, all of a sudden, Blender’s regular 3D view showed the leaves with transparency (see attached image 2). I have methodically gone through every Blender parameter and cannot find a difference between the textured view showing the transparency or not. Note, I am talking about the 3D modeling view, not a rendered image.
If anyone can shed some light on this, it would be much appreciated.
