• 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.

Animations stopped working

On my current project all animations stopped working a couple of days ago. I could find nothing wrong with any parts, animation tags, etc. Plus when I exported a simple animation test of a model with just a couple of animated parts, they didn't work either. So I uninstalled/reinstalled Blender and the Blender2FSX Toolset, after first reinstalling the FSX SDK per the directions here at FSDeveloper. Tried again. Animations still don't work in either my main project or the small animation test project. So my question is, with all the various versions of Blender, and Blender2FSX, is there a specific requirement that a certain version of Blender2FSX be used with Blender 2.79? I can't think of anything else that might be causing animations not to work. I get no errors on export, and there is nothing amiss when I review a "verbose" log. Very frustrating. Help! My FSX version is Acceleration. The version of Blender2FSX installed is 088.

What you might need to do then... is give us what you did step by step.... just on 1 specific model. How were the animations step up to start with...

They all worked perfectly until I started working on mouserects in the virtual cockpit. I think those are what I had started working on when things went south, and I hadn't been making backups. In Blender the animations appear to work fine. I can hit play and all of them work as expected. To make an animated part I would create its mesh, assign its animation tag, and attachpoint tags where needed, and then do its animation keyframes. One other thing I did when I started working on the VC and mouserects was to move just the VC parts to a new layer. I don't think that was problematic, though. In an attempt to find the problem I deleted the layer and those parts, in order to test the majority of the model in one layer, and it did not solve the problem, animations are still porked.

Here's something interesting. I tried exporting my version of Krispy's "test plane", that I last worked on in October, where I had all of its animations working good. Now, none of them work, which sort of confirms that it's not a problem with either model, but more likely something that went wonky with my installation of Blender and Blender2FSX. But I haven't got a clue.

How are you testing your animations exactly? In the sim or via modelconverterx?

Where exactly did you animations stopped working?
- Inside the Blender viewport? ............................. (when you were working on it in Blender)?
- When viewing the exported model inside MCX . (after being exported from Blender)?
- Inside your flighsimlator? .................................. (after using/importing the model inside your flightsim)?


and I hadn't been making backups.
TIP1 - Develop a decent backup strategy... here is how I do it: (with multiple copies and versions_numbers in very descriptive filenames)
1 st file - basemodel_name_v1.blend
2nd file - basemodel_name_v2_with_wings.blend
3nd file - basemodel_name_v3_wings_with_flaps.blend
4th file - basemodel_name_v4_wings_with_flaps_animated.blend
Use the [Save As] function as soon as you have achieved a (minor/major) milestone when building your model so you never loose more work then the last feature
>
Backup all files daily to another partition, drive AND external storage medium( usb-stick, usb-dsikdrive) and not to any cloud-service!

TIP2: have you already tried and opened the projectfilename. BLEND1?
This is an automatically created backup of your project file, which was created when you opened it for the last time.

Good idea about testing the exported model inside MCX. I just did that, and the animations appear to work just fine, there, but not once the model is copied into its FSX model folder. The main model that was last exported on 1/12/18 still animates in FSX, but if I do a new export from Blender the animations will work in MCX, but not FSX. Makes me wonder if something in FSX got corrupted. Existing animations of other aircraft still work in FSX, though. Pretty weird. I'll keep at it.

If the mdl is working in MCX but not FSX, is it possible your model.cfg is pointing to a different mdl? How many .mdl files are in your model folder? Also, double check you model.cfg is actually calling the right .mdl file. I've done that before when testing different ides out models out before realizing I forgot to modify the cfg to point back to the actual model.

The model.cfg is still correct, as is the one for "testplane1", the Krispy1001 project I worked on in October, with working animations, etc., which have also stopped working now after a fresh export from Blender.

Hello... What has changed on your system.. do you know of anything that has changed since 1/12 date?

Have you moved one (or more) of the necessary files? (XToMdl.exe, your modeldef file, FSX SDK Files)
Has your commandline / dos / windows / PATH variable become corrupted or altered (due tothe installation of other software or windows update cr*p)?

TIP: Is simply starting from scratch an option for you? Simple delete and start all over again (with the knowledge you now have)
Sometimes it is just quicker to through away the model, do a reinstall of blender , fsx and begin to move forward again (and make backups this time)

The only other possibility that I can think of is not initialize before resaving....from using the previous tool-set.. which might of reset or corrupted it, the animations that is.

Thanks for all the ideas, guys. I'm too far along to consider starting over. Well nigh finished with a twin-jet version of the Bugatti 100P, using two of the same engine used on the SubSonex. Here's a short video clip from 1/16/18, when animations still worked.

Maybe there's a clue here, that I don't understand! I used the FSX Verify Tool in Blender and got this error:

you have a curve in your export selection called fcurves? Either way that object is causing issues.

Thanks. I don't remember consciously adding a "curve". But if I did I've got to figure out how to locate it and remove it. I'll check the Blender online manual and read up on it.

you can find the object name fcurves in your object list I think.
