• 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.

FSX problem with animation

Some times if you move the model in a very long distance, it can disappear because of bounding box. You need to put a box and apply a transparent texture, no shadow to it.
 
Hi Jtanabodee, and thanks for your answer. I found that the problem is on path constraint, because if I make a little animation with short line, using it, and see it on simulator, the problem is the same. If I make an animation without it, the animation works fine on simulator. I used path constraint other times, but the animations worked well. I must to known what is the problem.
 
The sim doesn't support animation constraints: use Collapse to reduce it to keyframes.
 
Hi Hairyspin, I followed the tutorial and I used collapse as indicated on page 4. You can see it on my zip, where there is gmax's file. I created other animations using constraints some time ago, but the others work well ( see my postal truck on my liee scenery). The strange thing that the animation works fine on modelconverter, and it doesn't work on fsx...
mistery....:D
 
I have seen your file. I think the animation is too fast. You have 200 frames but the animation stops at 102th frame with the movement of model about 500 meters. Animation in FSX is around 18 frame per second. So you have around 5 second for that car travelling 1/2 km or 360 km/hr!!!!!!.
May be it is too fast to be seen?
One more thing, the animation should start and stop at the first and the last frame. I don't know this cause the problem.
 
I can see your truck in my KLIA2 airport now.



The problem is the bounding box. As I said earlier, you need to make a big box cover all the area of movement and put alpha channel to it. Making the material transparent and no shadow with FSX material will hide it from visible. You car will move in the box and always seen. It the car travel by itself with out this box, it will not be visible if it is too far from the center. FSX will "consider" it as too far and the game engine does not draw the texture to be visible.

I have attached the file so you can take a look.
1. Make alpha channel to your texture, just a small square is enough.
2. Make FSX material and make it default transparent, Z-alpha test at 128, Z-alpha write. No shadow.
3. Make a big box cover all the animation and apply the material to it. Map all the model of that box with that small alpha area in the texture.
4. Export the animation with that box.
5. In XML you need to add <NoCrash><NoAutogenCompression> too.

Please see the detail in zip file.
