• 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.

Sketchup physic - Animations possible?

Hi there!

I came across a google sketchup plugin called sketchup physics. I´m wonder if it is possible to animate objects for the flightsim?

Any experiences?

Thanks,
Holger
 
I don't have experience with it, but it will be interesting to know. The collada format can store animations, so if there is a plugin that allows you to make them it should be possible (I might have to improve modelconverterx a bit to convert them correctly though).

So looking forward to hear experiences with it,
 
I´m a step further ...

I was able to add a animation following this informative (and funny as well) tutorial: http://www.youtube.com/watch?v=Oc-n3IECUCI

Now the more complicated step is to export the animation. A simple export of an collada file seems not to be the answer. There is also a export option in the sketchyphysics plugin itself. By default you have 3 possibilities to export the animation (SKP, JPG?, PNG?)

Maybe you will try it yourselves?

Here you can get the plugin: http://www.heise.de/download/sketchyphysics-1145996.html
 
Hi,

I'll have a look, but I am on the ipad now, not behind my FS pc.

I did some browsing on the Internet and mainly found people asking for export to collada or other formats. So it seems like it might not be supported at the moment.

Also found this plugin (not free), but the only export they seem to have is to a movie. Maybe that's how most people want to use it.

NGX_ Why go to Sketch UP? Because it is free? Gamx is a very fine program but difficult to learn, but... a fine program.

Is there any reason why you would not try FSDS? Yes it costs $49.95 but for that price it is quite a fine tool to have. it is not quite as powerful as Gmax, but I have used it for years with very few minor complaints. Bob
 
Hi,

I did some more searching, but I didn't find ways to export animations from sketchup. Maybe I should add a simple animate feature in modelconverterx :). Just rotating or moving objects around should be possible.
 
Hi Arno:

I believe it would be very helpful to be able to import scenery object geometry from Sketchup into ModelConverterX, and then add animation features to imported objects within the MCX GUI. ;)

Many thanks for considering this feature enhancement ! :)

Hi,

I would have to see how I could make it possible to define the animations, since modelconverterx does not have an editing interface like gmax or sketchup. But I'll think about it.
 
Gee, if you are going to all that trouble it might be easier to export the object from MCX as a 3DS object and import into GMAX. The creation of animations in GMAX is not very difficult, especially for FS9. Any texture mapping is preserved, and with a click even visible in GMAX.
 
@jyarddog No it is not a question of money, I use sketchup because it is very easy to use and gives me all I need for developing. Only the option to export animations is missing. It is so much easier than gmax (for me) and further more I haven´t got a lot of time for developing. i have no idea what FSDS is (only heart of it, that it is also a developer tool) but I will take look on it.

I also did some more searching and I came across a programm called blender which can import collada and wavefront. You can add very fine animations but again it seems not to be easy to export that animation. Up to now I only was able to export it in avi (or other video formats).

But you all are right. I should go back to the basics...

@Arno Nice thoughts, adding that option to MCX!!!

I am looking to make new scripts for blender fs animation export. I dont have an eta on completion. I will probably be using c# to get the native interaction. plus I find c# easier than python at the moment.

Now if you have XPlane, all the tools you need for blender are out there. If you have an Xplane to FS aircraft converter (I havent seen one but havent really looked) then that may be a path to take.

I tried to contact the original script creator to no avail. It would be easy for him to bang these out as he already did it for blender 2.4x. Unfortunately they do not work in Blender 2.5 or 2.6 as the python mapping changed.

Im sorry about my post composures. I am swerving all over the place with no structure or organization.

Hi Arno:

At this early phase of defining what animation might be practical to implement for models created originally in Sketchup, perhaps we might first consider what you had originally suggested:

Hi,

I did some more searching, but I didn't find ways to export animations from sketchup. Maybe I should add a simple animate feature in modelconverterx :). Just rotating or moving objects around should be possible.

I believe that many with an interest in using Sketchup to create our scenery model geometry (and perhaps most of us ?) may be primarily wanting to create simple movements which are encoded within the MDL file when exported by ModelConverterX (aka "MCX").



If creation of a full graphical editing interface for manipulation of geometry in MCX for 'complex' animation is not feasible, then perhaps 'simple' animation such as "rotating or moving objects around" can be achieved within Sketchup itself by some methods which store the data for such transformations or central object datum RefPoint re-positioning coordinate paths within the *.SKP and/or *.KMZ file format. :idea:

Perhaps such static and dynamic geometry and coordinate data could then be interpreted and utilized by MCX when importing such objects for which the greater part of the work already has already been done by the author inside Sketchup ? :confused:



I don't think I'm the only FS developer here who would like to see use of Sketchup- and other '3rd party' 3D modeling apps- accommodated to the fullest extent possible by MCX ...as alternative(s) to use of GMAX / 3DSMAX.

MCX has already done a magnificent job of making many things possible which were previously believed to have only been achievable via GMAX / 3DSMAX and the MSFS SDK Modeling tools; perhaps it may now prove feasible to further expand the number of features MCX can convert for use in FS which were created by use of other 3D modeling apps ?

Some here may prefer (for a number of different and valid reasons) to NOT use GMAX / 3DSMAX ...except for creating / modifying certain types of objects and content that (presently) cannot be accomplished otherwise via an alternative work-flow. :rolleyes:

IMHO, import / modification of simple animations for geometry authored in 3rd party 3D modeling apps that is stored within the MDL by MCX when exported, would be a very valuable feature enhancement for the FS development community to have available. :)

Hi,

I'll have a think about it. But maybe starting with a simple rotate modelpart or move modelpart might be a good start. Most people only want that kind of simple animations. Those people that want the very complex stuff, normally use 3ds max or gmax already.
 
Hi Arno:

With regard to possibly being able to "rotate a model part" on a scenery object created in Sketchup, I'd like to inquire as to whether a particular type of 'simple' animation might be feasible.

I have a 1-piece, non-folding door on a rather old hangar modeled in Sketchup, that I'd like to pivot on a single hinge axis at one end (like an old-fashioned "pull-up-and-out-to-open" type of garage door).

If possible, I'd like to lift up the bottom of the door from the ground until the door is aligned horizontal to the ground.

Although the "real world" old hangar's large door actually used several chains on a rotary shaft with pulleys rather than hydraulics, this YouTube video shows what I'd like to achieve:

http://www.youtube.com/watch?v=OeMU-Iy2JPM


Hopefully that might be possible to achieve with a Sketchup model via animation options in MCX when you have have some time to implement and test that enhanced functionality. ;)


PS: If the 'door' object was made as a FS9 format MDL file, could it also be FSX aircraft pilot radio-controlled via CAT ? :confused:


Thanks for your further consideration of possible support for animation features in MCX. :)

Hi,

I would still classify that as a simple animation, so I guess that might work in the future.

If using fs2004 mdl files and cat it is indeed still possible to trigger animations in fsx as well.
 
Arno, has anything more been done in this area? I was looking at doing animated hangar doors, but was unable to find anything specific related to doing animation in Sketchup. Quite a bit on viewing or importing animation. . .but nothing that shows that it's possible within SU. Thanks!
 
I never bad-mouth a program, but unless there is a brand new plug in, I don't think animation as we know it cannot be done with sketch Up. Tat is why I pay money for a program that does stuff. Usually you get what you pay for. I am eager to hear that Sketch Up will soon have a plug in to be able to do animation. This would be wonderful. The animation Sketch Up DOES is the kind that sets you in the middle of a kitchen and then you can move around to see each wall, etc. I watched a tutorial about animation with Sketch Up. This was what was taught. I thought.... this is not the kind of animation we are looking for.

Punching holes in walls quickly is wonderful in Sketch Up. Animation? No. Gmax, yes but more difficult to learn. FSDS - not as powerful as Gmax but it does everything I want it to do. Had it for years. but Sketch Up does holes in walls great, better than the Boolean operation. Bob
 
I build a ship in SU and set the radars as individual groups to be animated in FSDS. When I export to .dae, I convert the radars to .fsc using MCX. A quick spin animation in FSDS then re-import the .fsc file to MCX to merge it with the parent boat, export as .mdl to play with it in AICarriers or place it with Instant Scenery. Works freaking great imo and very easy, so long as the animations aren't complex. I did a carrier blast shield and could not figure out how to articulate a piston while raising the shield, so I had to settle for a single pivot point for the entire animation.
The only real drawback to animating with FSDS is that you are unable to preserve the transparencies that MCX recognizes which are available using the SU .png format fence textures; which is kind of frustrating because the textures work great for making extremely convincing low poly grid style lattices, exactly the thing you might want to animate..
