I notice that whenever I have multiple objects along the line of sight, the realtime transparency is not calculated correctly. Specifically, objects that are highly transparent (alpha close to zero) can appear dark against a background of more opaque objects. In the example below, it should be possible to see through the dark cubes to the more opaque cubes behind them. Is it possible to have the transparency calculated more correctly ?
Longer explanation for those who are interested : I work at the Arecibo Observatory, and I’m attempting to import HI data from FITS files into Blender, so I can look at my data in realtime in 3D. Hence the thousands of cubes, which are imported via a Python script (so any fix needs to be easy to apply or at least scriptable). They render correctly, but that bit’s easy - it’s the realtime I’m interested in. If there’s another open source program that can handle this stuff I might be willing to explore it.
