• 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.

FSXA More LOD madness - 3dsmax

Messages
86
I'm having a heck of a time getting LODs to behave. In MAX... I've made this node:

attachment.php


"jetway7" is a simple cube box with a dummy animation.

When fsx is loaded, moving the camera away you can see "jetway7_LOD_050" show up, then disappear at about 5 miles away. The other LODs never appear.
None of these LOD jetways have animations applied to them, they are just static.

Any ideas on what I'm doing wrong?

I have been exporting with animations checked, and compiling the .x file with the /XANIM tag.

AFAIK you can't mix parts without LODs and LOD parts together in a single object. You can create a Dummy part and use that instead of the top part, but I don't think a "real" part will work there?
 
Thanks Tom,

So I replaced "jetway7" with an actual dummy, applied an animation and still the same problem. Only jetway7_LOD_050 appears at distance
 
New Questoin about LODs, using 3DS Max

My knowledge of LODs goes about as far as knowing what they are.

A new question:

I'm using 3ds max as well. I will be making LODs first time. All I know to try is the "Populate the LODs" function of the PP3D SDK Export and LOD Tool. Does this function actually make the LODs? Even, if does I question if it would work well for my test project. I have a hanger model of significant detail. It includes a animated door, external light fixtures and complete interior with I-Beam structure. Will the tool work OK on a model like this or would it be better to make the LODs manually? How would one go about that?

I maybe way off track. Guidance would be welcome. I there a tutorial anywhere?

Thanks

John
 
I figured out the issue I was having. Hopefully this may help others if they're having the same problem.

LODs cannot be too far away from your reference point
In other words the center of your 3d canvas is where the LOD model should be centered.


John, you don't need that tool to make your LODs, I believe it simply makes it easier to work with all your LOD models.
To make LOD in max, name each model.. NAME_LOD_100, NAME_LOD_050, NAME_LOD_010... etc
Always use 3 digits for the number. The actual numbers will depend on several factors so you have to play with them.
Make sure each LOD model is linked to a root, this could be a dummy or object. To export an LOD from 3dsmax that root object must be animated, so make a dummy animation and make sure you export with "export animations checked"

Hope this helps. Took me a whole week to figure this damn thing out.
 
Thanks

I'm afraid linking to a root is not something I have done before and making a dummy animation is not yet in my skill set either. I'll likely figure it out. The model I'm working with has an animated door. Is there a difficulty with that and a dummy animation?

Any additional thoughts welcome.

On LOD's...me too

I'm experimenting with LOD's in FSX with gmax.
I am experimenting with a sphere or multiple spheres at a high altitude so you can determine easily when they pop out.

My experiments so far tell me

(1) one LOD level will wipe out the others in a MDL with several LOD levels....I cannot simultaneously display two different LODs.

So far I believe that one MDL...one LOD level

(2) an LOD like myfile_LOD_500 wont appear and disappear at a 500 pixel image level.
