Red OK in tmfviewer?

[Guest Outer Marker]

Hello there everyone. I am new to the Mesh forum as I am primarily a sounds/FDE developer. Recently I have turned to mesh creation.I use 3-arc-second SRTM source data, and compile some fantastic bgl files. Naturally, I like to check things for "common sense" accuracy with the tmfviewer.exe included in the Microsoft SDK.To my untrained eye, the relief looks great, and an in-game test meets with my approval. However, 2 colors bother me in particular... please let me know if I am being paranoid or not:Red - I thought this means terrain below sea level. If so, is it okay to have a bit of this around low-lying salt marshes in the bays and lagoons near oceans? My gut says this is natural, and in-game I do not see any anomolies. Probably if I see red in the middle of a mountain range I should worry though right?Also, white - what kind of elevation range is this assigned to? I see it at the tips of mountains... I'm wondering if it is realistic for Appalacian mountains which are not as tall as the Rockies for example.Any input would be appreciated.Thank you!--Outer Marker.

Hello,The RED means a void value in the original data set. Voids are assigned the most negative value that can be represented with 2 bytes. Therefore you need to interpolate to change the "voids" for something acceptable. You can inspect the data before generating the BGLs with:http://www.ptsim.com/downloads/DEM2BSQ.ZIPRegards,LuisPS EDITED - In TMFViewer you can view the altitude in the bottom status bar as you move the mouse over the display.
