For 24hrs now, I’ve been trying to get a Grille unto a gate frame (without actually modelling the grille – 'cos that will drastically increase the amount of verts in the scene … and you know what that means). I usually achieve this in MAX by mapping an alpha texture of the grille unto a plane.
So, far doing the same thing in Blender 2.5-Beta has been serious pain. The lack of documentation (that is easy to access) is killing me. I have an alpha texture assigned to the alpha influence and so far transparencies render correctly (arrggh … a bit jaggy, but I think a change in the sampling rate can fix that). Frustration begins with any change to the mapping size. Results seem unpredictable … :mad:
The default is (1,1,1). Increasing those reduces the size of the map but not proportionally. Why is that? What am I doing wrong? As the reduction increases so does the anomaly. The opaque areas start to dominate leaving you with a very opaque mesh - and no grille.
