If you have ever added a wheel to a part that folds then you have probably ran in to the issue of the wheel moving but the wheel collision not?  If you figured it out great, if not here ya go.

The issue is the wheel has to be called out in the moving tool area.  I am going to copy some lines in from a plow that thumper was having issues with.  I helped him via a dm in discord.

So the key here is to know the part that is moving in the animation and the wheels that are in that part.  If you are using cylinder parts or not it will matter as well.  In the example the first 2 parts have cylinder parts (parts that move with a reference).  The last part is just a moving part with the wheels inside it.  It matters because the lines are closed off differently.  As a guide I used the krone forager to figure out how move the collisions.  They are invisible wheels.  The forage heads will pivot, they don't lock like a harvester header.

So here is the animation lines I looked at.

    <animations>
        <animation name="folding">

            <part node="leftWing" endTime="15" startTime="0" startRot="0 0 0" endRot="0 0 114.4"/>
            <part node="rightWing" endTime="15" startTime="0" startRot="0 0 0" endRot="0 0 -114.4"/>
            <part node="leftArm" endTime="15" startTime="0" startRot="0 0 0" endRot="0 0 -114.4"/>
            <part node="rightArm" endTime="15" startTime="0" startRot="0 0 0" endRot="0 0 114.4"/> 

            <part node="leftSupport" endTime="15" startTime="0" startRot="0 0 0" endRot="0 0 114.4"/>
            <part node="rightSupport" endTime="15" startTime="0" startRot="0 0 0" endRot="0 0 -114.4"/>     
            
        </animation>
        

        <animation name="lowerAnimation">
            <part node="bottomSupport" startTime="0" endTime="2.5" endRot="-20 0 0" startRot="0 0 0"/>
            <part node="topSupport" startTime="0" endTime="2.5" endRot="-20 0 0" startRot="0 0 0"/>
            <part node="swivel" startTime="0" endTime="2.5" endRot="20 0 0" startRot="0 0 0"/>        
            <part node="assistCylinder" startTime="0" endTime="2.5" endRot="-16.5 0 0" startRot="0 0 0"/>        
            <part node="assistRam" startTime="0" endTime="2.5" endTrans="0 0 -0.978" startTrans="0 0 -0.894"/>
        </animation>
    </animations>

The leftWing and rightWing are where the first and second set of wheels are.

The second set are in the swivel.

    <cylindered>
        <movingTools>
            <movingTool node="leftWing" playSound="true" wheelIndices="1">
                <dependentPart node="leftCylinder"/>
            </movingTool>
            <movingTool node="rightWing" playSound="true" wheelIndices="2">
                <dependentPart node="rightCylinder"/>
            </movingTool>
            <movingTool node="swivel"  wheelIndices="7 8 9 10"/>
        </movingTools>
        <movingParts>
            <movingPart node="leftCylinder" referencePoint="leftJointHyd" referenceFrame="0" isActiveDirty="true">
                <translatingPart node="leftRam"/>
            </movingPart>
            <movingPart node="rightCylinder" referencePoint="rightJointHyd" referenceFrame="0" isActiveDirty="true">
                <translatingPart node="rightRam"/>
            </movingPart>  
        </movingParts>
        <sounds>
            <hydraulic template="DEFAULT_HYDRAULIC_SOUND"/>
        </sounds>
    </cylindered>

As you can see the leftWing and rightWing have cylinder parts, the swivel does not.  That is why they are closed off differently.  The swivel line would not normally be there but it had to be added to call out the wheel indices.  As you can see all that had to be done was to add the wheelIndices comand in so that the game engine knows that there are wheels inside the moving part.  When indexing indices you start with 1.  So simply wheel 1 is in the leftWing, wheel 2 is in the rightWing, and wheels 7 8 9 10 are in the swivel.  I know this would probably be better explained in a video however I wanted to add it here quick to help those that may have had an issue.

Did you download all the suggested additional mods?

Thank you for the explaination. 

Good question 

Have you studied this?

I’ll check around. I haven’t used geese. 

Even though I’m not familiar I may be able to look at the lines you edited and see if I see an issue. Either copy the lines here or share the mod in a private message and I can always take a look. That and looking at your log would be a start as well. 

I have not used the configuration script itself I have only added config options used in default equipment. I will point someone here that is familiar with it. 
Sorry for the delay. I keep urging individuals to use this forum however we are all stuck in our comfort zone of using discord. 

This has been asked multiple times in discord so I thought I would add the subject here. To add a collision inside a vehicle the parent component in the rigid settings compound has to be checked.  Also in the child collision part compound child has to be activated. Like shywizard has commented these settings can be applied while exporting a model in the new exporter for blender 2.9 or you can add the following example to the par by editing the i3d via notepad. Refer to the compoundChild part below.  After saving the i3d in notepad and opening it back up in ge the grayed out box will be check like in the image below. 
 

```xml
  <Scene>
    <Shape shapeId="1" name="colPart01" translation="0.000757065 1.00552 -1.00853" compoundChild="true" collisionMask="8194" density="0.001" nodeId="166" materialIds="4" castsShadows="true" receiveShadows="true" nonRenderable="true"/>
  </Scene>
```

Huge thanks to fscommando for getting the site setup to add this video.

Shywizard did this awesome video, I wanted to be sure to share it here so he doesn't have to use his personal file space.

Correct @Poorboy good find. For those of you who aren’t aware if you make a new map from a previous one it will usually have an existing tip collision mask. You need to paint a new one because the original map will have all the road areas and buildings painted so that material can’t be dumped on those areas. What will happen is when you mow grass or even for example straw windrowed will not appear in those areas but then mound up as soon as you hit a spot that doesn’t have the painted area. You have to remove all tip collision area and re paint then run the script. 

Talked on discord. Anyone following it was a corrupt file. 

Yeah I’ve never checked to see if you can open it somehow with notepad but once the map is loaded scroll all the way through the console to double check for errors or warnings. If there is a missing shader it can cause that. 

Are there any errors or warnings listed in the console in ge?

That is new to me. I’ll see if I can find an answer. 

Sorry didn’t see this closed out. Did you find the bit settings?  They are in ge in the collision mask. 

I think we discussed this in discord and you found the issue?  It was an object in the i3d if i remember correctly. 

👍🏼

You will find the other scripts in the  Set Terrain Height/Placement tutorials  a great time saver as well, but a word of warning on the Set Terrain Height script, it cannot be undone  so always do a backup first (simple way is to make a copy of your map Dem image).

It is always better to experiment with different ways of doing things (on a blank map) and when you find one that works for you, use it and try and improve on it

@WrinkleysRule huge thanks for the detailed help. 

Good point. Are the modifiers being applied while in object mode?

Thanks to @WrinkleysRulefor the awesome tutorial. “Priceless”. As far as the modifiers go. It’s been a few days since I’ve been in blender however I’m pretty sure modifiers will disappear from the side panel once applied. Just giving feedback. 

If you’re too lazy to do the torque to HP math 😂
