• 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.

Blurry texture when zoom out

Hi guys, does anyone know why whenever I zoom out in MDX. The texture becomes broken and blurry. But when I zoom in, it become clear and normal again? I did not have this problem in older version of mdx, same thing when I imported models which was exported from the older version. (I'm using 1.7.0 now)

Do your textures have mipmaps? If so MCX will use them, e.g. show a lower resolution mip from further away.
 
I see you are using PNG files, they don't have mipmaps typically.

What you see in the screenshot does not look very weird. When viewing from a distance the textures will have to be reduced in size, since there are less pixels available to draw them on. With certain patterns in your texture it is common that you get this kind of moiré effect. If you export to a format with mip maps (as FS usually uses) you can reduce it in the sim.
 
Hi, I have tried what you said, and it worked. However, when i do the same thing for the specular texture of the glass, I do not know why it doesn't create the correct mipmap :((, I exported the model twice. The first time, everythings is perfect, but for the second one, the problem arised. Anyways, thank you for helping me
 
I always experience them even with normal .BMP files (if the image is 1024x1024 big, the size would be 4MB without the mipmaps. But 5.33MB with the mipmaps). I wonder if there is an option in the program that could just disable it...
 
Well, of course mip maps increase the file size (they add 33% to the file size), but the benefit is better performance because you can use a smaller version of the texture in the distance.

I am not aware that we can control if the package tools adds mip maps or not.
