meatshield 13 Posted June 18, 2014 So i've started work on a terrain, its 4096x4096 in size. Now from what i've gathered, if you do a 1024x1024 map, you'll need a 10240x10240 sat map, 2048 is a 20480x20480. Now going from that i'm gathering i'd need a 40960x40960 sat map ... what i'm wondering .. is can i use a smaller sat map texture than 40960x40960 and make it easier to work on, or do i have to struggle on?

Snake Man 407 Posted June 18, 2014 You forgot to tell us half of the size information, I suggest you check PMC Editing Wiki: Terrain Grid and Cell Sizes page and let us know what size your terrain really will be. Share this post Link to post Share on other sites
meatshield 13 Posted June 18, 2014 the are covered is 589.38 km2 + a little sea around the edges, i basically just did a 40960x40960 box in global mapper that covers the island nicely, 20480x20480 was to to small and i really didnt want to squish it. So i guess it would be grid size = 4096 cell size = 100 Never been to good at maths so it might be off. Share this post Link to post Share on other sites
bushlurker 46 Posted June 18, 2014 cell size = 10 - I hope!!! Sounds good... 4096x4096 heightmap with 10meter spacing/cell = 40960x40960 meters total terrain size. Satellite image of 40960px x 40960px will produce 1 meter per pixel imagery - a decent "standard" resolution. Yes - that size of image is almost impossible to work with as a "single image"... You're using Global Mapper however? - you can use the "Gridded Output" option in the Rasters Export options to save the big 40960x40960 image as 4 x 20480x20480 images - load them individually into TB and rearrange them in a 2x2 grid and that should be you with a "40960x40960" which TB will accept and use... Yes - even after that, TB will be a little slow to work with - mainly things like crunching the layers and processing all the tiles... Its BIG, but its definitely a viable size... Yes - you COULD save your overall image out of GM at 2 meters per pixel - that would give you a 20480x20480 image covering exactly the same area, but at lower resolution... It'll be generally quicker to work with all round and there's nothing to stop you switching to hi-res later... BUT... Terrain Builder works differently from Visitor 3 - it's much more like Visitor 4... You load your imagery first, and THEN decide on which resolution you'll "sample" it at for your final terrain - so, once that bigass 40960x40960 is loaded and in there - you can simply set "2m/px" at the Mapframe Sampler properties stage, and you'll be working with 2m/px for speed... later, all you need to do is change that parameter to 1m/px - TB will "resample" the underlying data at full res and - you have a 1m/px terrain! so - I'd load up the full res data - then it's in and you don't need to worry about it any more - you can sample low for initial speed, and later on, sample high for quality... the same underlying data will do for both B Share this post Link to post Share on other sites

francis 4 Posted December 29, 2014 hi , i try to create a new map with grid size = 4096 cell size =10m terrain size = 40960 all work fines only if i export the sat image with a resolution 4 px/m and its pretty faster for packing this in pbo files. but all the satellite image look like little bit blur . i tryed to done this map with a better Satellite image quality and its almost impossible to me to done that. after 5-6 months/20 hours a day to try with dodge or cheat in any kind of way .I cant done nothing better than 4 m/px when i try with a resolution of 2m/px thats create new image in the layers folder, but after export the wrp, when i use buldozer or test it in game , this never allow me to play or see it into game / buldozer .does anyone know how to make a 40960 X 40960 terrain size with a perfect satelitte image of resolution 1m/px (i hope BIS know it) all forum i open and thats talk about terrain size of 40960 all info was wrong with me i tested with one Satelitte of 40960 X 40960 px ,after 2hour of wait then the TB crash, i have now 4 image of 20480 X 20480 and one mask of 4096 X 4096 (in TB i open this property image, and set 40960 X 40960 size) If anyone can help me with this mess ITS WILL BE APPRECIATED . and too , nice one TB "Dev" 8192 grid size always Crash just lol at this !!!!! why this option is available to see but not for making the terrain . this look like a program from another engine like VBS and the "devs" dont know how to disable this options or allow us to use it!
