First, thank you guys for putting the beta 4 together! Great work adding all that stuff.
btw Adaptive bloom by Mark Blosser is awesome! (I tested it before in beta 3).
Things I found so far in b4:
1. Bug (test level): huge water plane is added automatically to the scene, for some reason. Solution:?
2. Bug (build level): fpsc forgets to add some files to the build folder (i found lightray files so far). Solution: Copy the lightray folder to the build files, enabling postprocess 3 without crash.
3. Bug (build and test): postprocessing=4 crashes the program. Solution: Maybe similar problem as above?
4. Bug/feature (build and test: lightray is working as expected only if "lightsource" is aiming to the south. (see images)
Solution: I am quite aware, that as it is postprocess shader it may be impossible to fix.
However, with an option to "on" or "off" the shader by script, it could be used only in rooms where lightsources (bright areas) are properly set up?
Or maybe, coud it be fixed on certain color only?
5. Performance (built game):
postprocess setting 1 nice, postprocess setting 2 nice (bug with strange halo around entities. could make nice "hot air" effect, if tamed

. Also, is not supposed to be bloom PLUS depth of field?), postprocess setting 3 very poor, setting 4 crashed.
