Textures Rules?

Recommended Posts

Hello,Maybe an easy question about textures.- I am covering my airfield ground with a poly textured with an aerial photography. This phot is 3072x2048 in size. It is cutted in 6 squared parts (1024 each side) and assembled with gmax in one plane polygon divided in 6 segments.The 6 images are used as DXT1 mipmaped files.My problem is the display of kind of blured lighter lines between each division when inside FS2002. Those lines are appearing at a small distance from the plane so I expect them to be linked with the mipmaps. I looked at the images files but everything looks OK.Does someone know what the reason is ?- To avoid those blured lines I tried to display my image in one piece instead of six and then I tried to use a single texture file.My first try was an image in size of 3072x2048 DXT1 mipmaped. It doesn't show probably because It needed to be a multiple of 256.So tried a 4096x2048 DXT1 mipmaped and it works (but is blured).Then I tried the same but without mipmaps and it does not display in FS2002.Then I tried the same with an image size 2048x2048 DXT1 NO mipmap and it works !Who knows what is the rule with textures ???????FLorent

I don't know exactly which textures FS can handle and which not, but I have heard more problems with big textures lately.But back to your first question of the lines. I think you didn't have the mapping of the texture 100% correct. Then it can happen that a small part of the left site of the texture is displayed on the right site. I think that can cause the effect.Arno

Hello Arno,Thanks for your answer.How to correct the mapping in that case and how can I check if it is the reason ? Again if I look at the textures files they are correct and when I look at them in Gmax they are correct also.Regarding the rules for using textures in size and formats and mipmaping do you think about an existing source of information ? Maybe a more detailed Imagetool doc ? Are the options in Imagetool such as "border" and "fold" usefull ?

When you zoom in very much it also looks correct in GMax? Then I think it is not a mapping problem :).I think you can best wait if someone else posts his thoughts here. I don't think there are some extra docs or so.Arno
