Global Mapper v25.0

Flythrough rendering question

Just a question about rendering a fly-through to mp4 video (latest version). It seems that the rendered video looks the same as the preview. On the image, the blueish areas are simplyfied-out so when the video moves frame by frame, some artifact/thinout effect is visible on the final video also (where background flashes throught the landscape) How to override this? Thanks.

    When rendering Lidar data, there is a certain amount of point sampling/simplification involved. The points represented by a given area may change depending on the point of view and can cause a flickering effect during fly-though.(Not sure if that is exactly what you are seeing.) This is not something that can be overridden. When a fly-though is previewed, the rendering quality is reduced to provide faster frame rates. There was an issue (#22507) that was corrected a while back where this lower quality was still being used when rendering to a movie file, and perhaps you are using a version that pre-dates that fix. I would suggest that you contact Blue Marble Geographics Support via e-mail ( The exact version you are using, and a sample of your data would help us assess the issue.
