This does not happen for all the clusters. Some of the others are still colored in the orthographic projection. Although it seems, that the color changes slightly (from magenta to a some lighter pastell tone)
Yes. I found this feature when changing to the XY orthographic projection. Actually I think I see some slight color change in the other orthographic projections as well, but there the clusters are not completely black.
About colors getting brighter – I think this is due to specular reflection as in orthographic projection you look at the box faces directly. Try switching it off in viewer “Style” tab.
Now, for the black ones, I can’t reproduce the problem with standard demos in tutorials/eve. How do you create the boxes? In 3D, they look ok from all angles, also in outline and wireframe mode (keys “s”, “r” and “t”)?
Can you post a simple script that reproduces the problem?
I think I found the problem: for box-type kBT_FreeBox the normals were not computed for every face – fixed normals were used instead. Under some circumstances this could lead to the observed behaviour.
