No, there isn't factor in the motion of the aircraft... We can work to improve this. The origin and the wind have to be tested... and maybe adapted. Hi Nicolas, If I look very close with both snow and rain, I can now see that the aircraft motion through the falling particles seems to be correct ... it's subtle and sometimes hard to see depending on the lighting and background color ... and subtle is probably good for these effects. I think what confused me was that even at flying speeds, there is still a downward elongation of the particles with rain which tricks my brain into thinking they are falling straight down. If the streaking could be made opposite the direction of motion some how (???) I think that may make the visual effect more compelling. I'm not sure if that makes any sense? But the overall effect of the snow and the rain is quite good. Also, you work to tie this into the metar reports is also very nice. Question: is it possible to tune the amount of snow/rain? Perhaps a future update would be to ease slowly into snow/rain rather than make an abrupt change (if that is possible to do.) I think if we could redo the draw order (or change the near clip plane?) so that precipitation doesn't appear to be inside the cockpit then I would be happy to see this new effect get committed to cvs, and we can work on refining some of the subtle perceptual details later. Best regards, Curt. Actually, even at typical car (automobile) speeds, transitions into and between rain and snow tend to be quite abrupt - perhaps just a second or two at ~50 mph. However, once you're in that weather type, the variations in density seem to be much slower. LeeE - This SF.net email is sponsored by: Microsoft Defy all challenges.

When I fly over the area , it is covered by mixed forest... I few south and there are shrub cover trees on a DeciduousNeedleCover material patch. The ground texture changes accordingly , just not the tree textures ... and yet I see tree sizes change correctly at the material boundaries I hadn't reaaly noticed this effect until I started flying around and checking terrain using geod.info so didn't expect it to jump out at anyone else Cheers -- SydSandy [EMAIL PROTECTED] - This SF.net email is sponsored by: Microsoft Defy all challenges.
