Ah I see. Thanks. Although, I already Implemented it the other way now, and it works. But maybe I'll refactor it at some point.

I see, so the way to go here is to modify Config.glTransparencyMul then? Could I for example modify it through a sine wave with each frame rendered?

Hello

I'm using JPCT-AE for something serious.
It is a medical application where a user can select a pain point on a 3D model of the body. Right now I implemented this pain point using a Sphere primitive without texture and set the additional color to color it. Now I'd like to make it pulsate by making it more and less transparent over time. How would I implement this? I know there is a setTransparency() method, but this only accepts integers (IMO the JavaDoc could be improved here to explain some more what range of values it accepts and what they mean). When I set the transparency to -1, the object is fully opaque and setting it to 1 seems to make it fully transparent. How can I vary the transparency in order to achieve the desired effect?

Thanks for this easy to use lib and your help!
