Hi,
Yes, in FFP they don’t interact. If you want some Light+Fog interaction you need to write a shader. Fog is simply a color “added” with respect to the distance from the viewpoint Cheers Sebastian From: osg-users <[email protected]> On Behalf Of OpenSceneGraph Users Sent: Dienstag, 23.

Cheers. 2020년 6월 23일 화요일 오후 4시 47분 48초 UTC+9, OpenSceneGraph Users 님의 말: Hi, As there is no concept of day/night in OSG you need to adapt the color based on the time passed (you can use the osg-time for this or use a separate timer) . Simply adapt the fog-color during the update-traversal. Cheers Sebastian From: osg-users <[email protected] <javascript:> > On Behalf Of OpenSceneGraph Users Sent: Dienstag, 23.
