Manchuria WIP

Recommended Posts

I am still tweaking the colors and sharpness. I think with the current terrain engine, higher altitudes look a little hazy and lower altitudes are fuzzy. I'm trying to get the higher altitudes to look more crisp and vibrant and lower altitudes more clear.

The terrain looks great at high altitude, but the biggest issue is it loses a lot of detail down low. The terrain engine compensates for this by using a noise texture, as you can see in the lower shot. I think the best fix would be to increase the visibility of the noise texture in the graphics.cfg file, which is what I did for the lower pic.

That looks more real, but yeah - it does lose a lot of stuff down low. Are you able to fix this by using LODs, or would that be impossible or plain impractical?

It's blurry down low, and its more obvious with a diverse terrain like Manchuria vs something which doesn't have as much variation like Nevada or something set in the desert where the terrain is mostly monochromatic... the only way to make it less blurry would be to use higher resolution imagery, which is not available to the general public for this region right now. Then again I think the Black Sea map also has this problem, especially for the farmland so they created farm textures... which I'll probably modify and use on the farmland areas too.

Looks like a lighter color noise texture works better for this new set of satellite imagery, and the color blending is better.

Problem was the old texture was dark, which worked for the old satellite terrain set just didnt work for the new set...

Excellent progress, T-Bone! In that last batch, the low and medium altitude shots in particular look great. You've got the noise texture working for you very well. However, the 25K shot is still quite bland and blurry, IMO, especially if you look at the bottom right corner. I hope this is something that can be improved, but I'm not sure how easy that would be with these resolutions of satellite imagery.

The satellite data is landsat7 which is only 15m x 15m per pixel. There are higher resolution satellite images but those are either classified, or they aren't continuous throughout the whole region, and also have other problems like they were taken during different dates, and would have portions of missing data at their resolution. The satellite imagery looks better at higher altitudes when you turn up the color contrast and saturation, but down low clashes with the terrain textures as seen below:

It is a tradeoff, and I'll have to keep tweaking it to get the best results. I think however that the LOMAC/DCS series put a lot of emphasis into ground pounders so I'd prioritize the appearance of terrain at lower altitudes more.

I've been doing some research into what the actual colors should look like and what kind of terrain to use. Apparently most of this region is Polar and Alpine desert and Steppe Tundra.

Obviously with the limitations of our game engine, we can't reproduce 100% accurate colors, but I'm shooting for a good representation.

Have you tried changing the contrast and saturation for ONLY the LOD2 textures? Those textures only show up at a distance, so in theory, you could increase the contrast and saturation for those while leaving the contrast and saturation for the LOD0 textures as they are.

This is just a test of the LOD0 textures, so I have no idea how the LOD2 will effect them yet. I'm thinking about messing with some of the entries in graphics.cfg for the noise distance. Also I don't have FC 2.0 installed yet because I am going to get a new computer for everything soon. It seems like FC 2.0 makes the terrain look bolder, so I'm going to wait and see if it has any effect before modifying the satellite textures any further.

I created a new noise file with more detail and more color contrast. Also I tweaked the satellite imagery. Once again this is the FC 1.12 engine... I'm still waiting on a new computer to test this terrain in the FC 2.0 engine.

Looking good there T-bone. When are you planning to add 3d objects? (cities, villages, roads, railroads, airfields, trees, power stations, power lines, dams if there are any and rivers?)

I'm making good progress on finding a way to present terrain realistically from all altitudes in the FC2 engine:
