• 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 to all you, i have a question about what is better to do to increase the performance of my scenery, i made some object whit gmax but my question is that what is better, a lot of objects in one bgl or just a few objects in the same bgl. And if somebody can tell me some tips to increase the performance when i develope my scenery, i dont now maybe about the textures or something like that.

Thanks a lot.

Cesar.
 
Hi,

The amount of objects in a BGL does not matter that much, a library BGL can contain hundreds of objects. What matters more for the performance is that you do not build your entire airport as one MDL file, splitting it up in different MDL files gives better performance. For example one for each hangar or buidling. They can all in up in the same library BGL.

Also great for the performance is to reduce the amount of drawcalls as much as you can. That means that you should use as little textures as possible, just put as much as possible in one texture sheet.

Another way to increase the performance is by adding levels of detail, so that the high detail is only drawn when needed.
 
And, finally, one last performance tip that usually gets missed: Always, ALWAYS create mip-maps for your textures. Leaving them out might get rid of the dreaded "blurries" but your scenery will be slooooooow to load and display.
