I’ve just started learning Blender, and 3D in general, so I apologize if this is a “stupid” question or if I’m using incorrect terminology.
I’m currently doing a simple animation of a helicopter for one of my colleagues. The helicopter-model was bought (textures included). I’m animating the rotors’ rotation and the helicopter’s movement.
I did quite a lot of testing with motion blur (different rotor rotation speed / motion samples /camera shutter), but was not quite happy with the result. There was textures of spinning rotors included with the model, and since the helicopter always will be flying (no landing or take-off), I started testing with these instead. (Attachment #1) The main rotor is looking good, but I need to do some further tweaking on the tail rotor.
Transparency: On (Z Transparency)
The tail rotor’s material is a combination of two .bmp textures, one for color and one for alpha. It renders correctly. (Attachment #2). But I would like to decrease the opacity of the rotor as well, so that it is less visible. How can I accomplish that? I’ve tried adjusting color / alpha influence and DVar, without success. Do I have to manipulate the alpha channel (.bmp) in Photoshop etc., or can I do it in Blender?
