Hello! My problem is... well... annoying. I "borrowed" car model from warehouse in Google Sketchup. I Put it into Outerra, "borrowed" script from theshanergy and modified it to work for my car. Reloaded and... Car is hovering! I also cant drive it. Even animations dont work. Also the second problem is that wheels from right side dont have a texture, when those on opposite side have. This same problem appears on door, but this time door on left side are without texture.
Here is script:

Hi!

So you certainly have a script error which will break the physics. This is most likely caused either by the use of a method or function parameter that no longer exists, or a syntax error.

Press Alt + L keys to bring up the console, you should see something about an error in red text and it will indicate the line of the first error in brackets, like (231) and possibly what type of error it is, such has Object has no object, or expect identifier, or some such error.

Looking briefly at the code I assume some of the joints from theshanergy's vehicle were called in get_joint that do not exist in your model, and it looks like some of the methods in the function update_frame are expecting variables from the function action which is no longer supported since the extended controls were implemented.

I might suggest you begin with an up-to-date script, such as t817.js found in Anteworld/packages/outerra/t817.js and reduce it to only the necessary code that applies directly to your vehicle. I will also use a JS debugger to identify syntax errors, online ones exist such as jsbin.com

In terms of textures, check your .mtl file and make sure there are corresponding texture files for the material albedos, as they may not have been imported automatically or exported when you saved the FBX file. There is plenty of information about that elsewhere on the forum.

Regards,
Uriah

Hi!

I checked the t817 script. Remade it a bit and now... well just say... only one wheel can rotate and it doesnt rotate as it should. It should be normal, but it can just rotate 360 degree and not even at center.

About textures, i exported it as Collada File, because i have free sketchup.

DID THIS!!! CAR FINALLY IS DRIVEABLE, But...

It's like center of mass is badly placed, so car flips on roof and fall underground.
Now wheels are spinning like not on center, but on edge
Last thing(s):
1. Car cant turn. Probably something with script.
2. Some textures just disapper. When I export them there is no any folder or texture file in .dae location.
NEW 3. Car center of mass is a bit more on drivers side, that makes car flip underground when turning.

Please help me if there is way to fix that.
Script:

Need a source model to help.

Hi,

I am going to assume you need to fix the joint pivots before you export the model. Wheels will rotate around the X axis for rolling forward and backward and rotate around the Z axis for turning left/right, which is done by the method this.animate_wheels(); near the bottom of the script. Other more advanced models may require you to move and rotate the wheels differently without this method using move and rotate methods, but for most models the animate_wheels method works as long as your pivots are correct.

First, make sure your model is oriented in the correct direction, where the forward vector is aligned with the +Y axis which should be pointing directly forward form the perspective of the driver, and if not you wheels will obviously be rotating around the wrong axis. If you model is already aligned correctly, then you may need to Reset Pivot Transform, and/or Align Pivot to World. I use 3ds Max, so I have no idea about how any of this is done in Sketchup, but there will be tutorials online for that. I've heard Sketchup is "better" than it used to be, but if you are serious about modelling I would recommend using Blender (which is also free), and at the very least exporting to FBX, as there are issues with Collage in general and I do not use it. FBX importer shortcut if Ctrl + F7.

Another helpful thing is to visualise the joint pivots in Outerra with debug keys enabled in eng.cfg ( debug_keys = true, ) using Alt + 7 keys. You'll see the main axis which is the large axis and small axis for each joint. Green vector will be Y, Red is X and Blue is Z. This can help determine if the pivots are aligned or located correctly.

If you have further issues please post a download link with your entire package and I'll take a look at it. You can use the OTX exporter from the vehicle menu in Outerra, just select your car and click the Export button.

Regards,
Uriah

In regards to textures, you may be missing materials or textures. You may have to compress to DDS format manually using nvcompress.exe (command line interface) or something like TheCompressonator. Again, plenty of information on the forums about textures/materials, but my assumption is you are actually missing materials due to exporting the wrong material type or because of the Collada format, one of many reason I only use FBX.

[OskiekSL]

Hi,

I think its just something that happend to sketchup. Last time when i exported house I made, there were textures, gonna try to fix and tell you

[OskiekSL]

Hello. I asked on SketchUp forum and they told me, that its only colors, not textures. But they dont apper in game.

If you exported from sketchup as a .dae and used the default importer, components can be problematic (especially with models from warehouse) as they can show up as weird color/reflections once in Outerra. You better collapse these and make groups. But sometimes even when collapsed it still can have these weird reflections.

On the other hand, the FBX importer work well with components and they import fine but any pivots you set in sketchup will be be revert to the world axis on the fbx export. So you would have to edit the pivots in another program (blender, max)

[OskiekSL]

Hi,

Can you tell me if I can import kmz file or export fbx from sketchup, without any paying?
Also could you make instruction how to make it work, also how to fix error with turning and fliping on roof?

[M7]

yeah you need the pro version to export as fbx. But you can still try the .dae export and make sure that there's no component left. It might work out fine.  As for the .js config, i dont really know to set it up myself.
