Hello community,

Recently I started modeling in 3DS Max and I imported one of my models. I added a simple animation to the object but when I load it into AppGameKit it looks exploded. Do I must take care of some check marks at the .FBX export window?

Thank you!

Have you tried saving as a 3ds object

I tried now, but I can see just the bones animating, not the mesh.

The problem has been solved by select Autodesk Media and Entertainment as "current preset". Don't know what check mark did the whole model explode... hopefully in the future I'll not have such problems and neither do others.

PS: Current Presets is located on the export window.

Nope, the problem was not solved by that "solution" I added another bone the mix and it ruined the object as before... Sorry

Maybe its 3DSMax in general?

Could you create a smaller object with less detail like an animated cube or something to see if it does the same

Im not good with any modelling software - i prefer OBJ though but least giving you something to try to elimate issues

Are you perhaps using

LoadObjectWithChildren

command, which loads i beleive the bones structure too.

Im way not advanced enough here to give you an 100% solution

Have you perhaps transleted all the bones to your object within 3DS Max to X-0, Y-0, Z-0 so the are all translated to the main object

I was using bones and skinning with the model itself in 3DS Max, yes. I loaded the object using the command "LoadObjectWithChildren", since it is the only command that accepts animations. Loading an .OBJ with that command, to support animation, is not detected as an object with animation, sadly. I will try again with rigging animation. Temporary I will use a non rigging solution (animating the object by dragging the mesh itself, not the bones). You maybe have a point regarding the translation of the bones, sure enough.

I have not fooled with animations in a bit, but I remember there are lots of pitfalls.

Are your bones scaled? Scaled bones will not export properly. Be sure to Apply all scales and rotations before exporting. This is usually where I go wrong. I forget to apply rotation and scale on the bones and model.

Do you need to recalculate the bone roll? This has also screwed me over more than once.

Good advices regarding the rotation and the scale. But no, I do not scale or rotate the bones. Just moving them.

That's cool

Does that apply to the translate / position too??

Just an idea

Could you possibly load the model is some other well known modelling tools - like Blender and such like to see if its the same?

Well, only if Blender knows how to import .fbx, or .dae or some other formats. But I don't know if this process is 100% compatible with the bones and other structures from 3DS Max.

ok - so it looks good in 3dsmax?

did you check the translations "Position data" on the bones? - they all need to be 0,0,0 and relative to the man object

this is pretty much similar to what

FixObjectToObject

command does in AppGameKit when want to join things together, every object fixed must be 0,0,0 relative

Didn't had the chance to test it out with the bones. I have one last problem till I fully understand how it works and then I'll go to the bones section and I will write the problems down, here on this topic or make a new one for those who will encounter problems like mine.

The problem that I got is: When I export the model without having any animations, I can easily apply the textures (in one as a result of the UVW). However, when I add the animations in 3DS Max, I can't texture the object with the same method. I must retrieve the "children" and then apply the textures individually. I want to manage to texture the object the same way when it doesn't have any animations.
The model has multiple textures!

Now that's a must to try! (What you wrote about the transformation) I will try it after solving the problem with the textures

Im not 100% on fbx models, but in OBJ you can individually materialize each bone. In OBJ its called a Group.

Can you convert the model to OBJ at all with textures to see what the OBJ format looks like

See the attached photo. The animation was done WITHOUT bones. It should've worked as fbx worked.

OBJ must work differently to what i expected. - thanks for trying.

Stay with your FBX model but please do check your transform.

Its experimentation, really. It's absolutely wonderful to take time and think about what you want to achieve. I can't explain in words how satisfied you can be after the eurika moment!

Its nice of you to say that first of all.

Programmers are problem solvers, so we need to go through the motions to see what we are forgetting.

So your loading your object as a simple new project but your additional objects look exploded?

Once converted to a different format OBJ for example... Does this load the same?

If yes - then 3dmax is been silly and at fault

JUST when I add the bones to animate. If I animate the model without them, all good for the geometry. Tomorrow I'll add the bones and reset the pivots. It has to work... can you imagine how will be like to animate a hand and a gun without bones? I'll be done in 65 years.

Fbx + bones => explosion
Fbx - bones => alright

Obj + bones => not tested
Obj - bones => just a static object, but all good.

I bet your hand peice is at 0,0,0 and your receiver object is at 100,0,0 instead of -1,0,0 lol

Upload the file, and I will take a look at it if you want. Or send it to me in a PM if possible.

Also, yes FBX does take special export options, at least out of Blender. I do not use 3ds.

Brothers, it messes up with my head. I added the bones again and it worked ok, the animation works. Golelorn, I'll send you the model in PM, if someones else wants it, just text me.

Another thing, (and it's very important) why in the world, the texture (if multiple textures) apply on the object or on the object's children, there where is a skin modifier? Just then...
