• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

hi

i have a question:

if i use textures that are not equal from both side for example 1024x900 FS9 display without problems the ground polygon ( but i think i m not sure yet thzt get sligthy slow to load the scenery)

why we mist respect 1024x1024 if differents sizes works?

900 is not power of two. the power of two is 1,2,4,8,16,32,64,128,256,512, (768 in some places as 512+256 3DS max gives this value for some reason), 1024,2048,4096,8192 and so on and on.Powers of two are often used to measure computer memory for example.
Try implementing wrapping texture-mapping in software and you will quickly discover why POT sized are desirable.
You can use 8X1024 or 2X4096 tho. It is not necessary always square.

Some newer graphics cards can render textures that are not a power of two. This is generally not very useful for loading art.
After all, game art is usually created in POT sizes no matter what.
 
Hi,

Also when you make a dxt compressed version of the texture you will find out it does not work if the texture is not a power of two in size. The compression algorithm is assuming powers of two.

I am even surprised that fs2004 does show the texture. I thought these textures were not loaded at all.
