Yes, I've tried quite a few methods. That's why I settled on the 16 bit to 8 bit conversion via Photoshop. You get the most resolution out of the 16 bit data as is reasonably possible. Obviously, converting a huge 106 MB BIL to a 4K x 4K file is going to to sample down a lot of data- but the details are still extremely good- way better than sampling a 10 meter even. But 10 meter is still way better than 30 meter, etc. I'm trying to reach those people out there who have been trying to use the widely available 30 meter data and not getting good looking terrains in Vue. I would bet a number of people still load a 256 terrain in Vue and add in a higher rez TIF- and then rez THAT up to 1024 or something- not realizing they are losing tons of detail right there. Loading 4097x4097 terrain data AFTER resizing to 4097x4097 in Vue gives you the best possible data resolution. I have gone up to 8K (as mentioned above) but I can no longer open the Terrain Editor in Vue AGAIN once I have closed it. This is also why I would like to see E-On support the 16 bit TER format. Following the specs on this Open File Format would lead to CLEAN 16 Bit Terrain data in Vue without the Staircasing effects. That's why currently even importing 16 bit TGA or TIF into Vue only results in Vue converting the great 65,536 levels of gray-scale detail into just 255 levels (8-Bit). Obviously there would be a STUNNING DIFFERENCE in detail with a true 16 bit TER import. Again I would like to suggest people try the TerraConv software- it provides another great terrain data conversion and import process into Vue- and saves the RAW export-import steps as shown above in this thread. I am hoping that once Vue users better understand these data issues that they will ask E-On to ADD 16 bit TER file import as an option- OR- at least a TRUE 16 bit TIF or PGM import. BRYCE has added PGM as an import option since Bryce 5. However- I don't know if it actually supports 16 bits since I haven't tried it in B5.
