Away3D Forum Unable to parse 3DS files

I can’t get a mesh out of ANY 3ds file, mine made with Blender or a downloaded one.

Here’s the code:

package ie.aro.floorplanviewer.controller
{
 import away3d.events.AssetEvent;
 import away3d.events.LoaderEvent;
 import away3d.library.AssetLibrary;
 import away3d.library.utils.AssetLibraryIterator;
 import away3d.loaders.parsers.Max3DSParser;
 
 import flash.net.URLRequest;
 
 import ie.aro.floorplanviewer.model.BuildingModel;
 
 import org.robotlegs.mvcs.Command;

 public class Load3DModelsCommand extends Command
 {
  [Inject]
  public var buildingModel:BuildingModel;
  
  private var _furnitureMap:XML;
  
  override public function execute():void
  {
   
   //_furnitureMap = buildingModel.furnitureMap;
   AssetLibrary.enableParser(Max3DSParser);

   AssetLibrary.addEventListener(AssetEvent.ASSET_COMPLETE, onAssetComplete);
   AssetLibrary.addEventListener(LoaderEvent.RESOURCE_COMPLETE, onResourceComplete);
   AssetLibrary.load(new URLRequest("data/armchair_29.3DS"));
    

  }
  
  private function onAssetComplete(e:AssetEvent):void
  {
   trace("Asset Complete");
  }
  
  private function onResourceComplete(e:LoaderEvent):void
  {
   trace("Resource Complete");
   var assetIterator:AssetLibraryIterator = AssetLibrary.createIterator();
   trace("Meshes in library: " + assetIterator.numAssets);
  }
 }
} 

Don’t worry - the listeners and all aren’t staying in the command - they’ll be moved out. And yes, the command isn’t getting garbage collected.

I’m getting the RESOURCE_COMPLETE event ok, but no ASSET_COMPLETE events, and the assetIterator is counting zero assets.

I’ve tried the Max3DSParser and enableAllParsers as well - same result.

Any ideas? (If everyone but me isn’t partying at Max…!)

Same here I tried exporting 3ds models from blender and Lightwave and could not get them to load right. But if i go back to away3d 3.6 they load. material just does not show up on model. And for some reason models are mirrored.

When i updated my code to the newest GIT it made my 3DS models not to load. After RESOURCE_COMPLETE event dispatched loader3D always has 0 children. But if i roll back to 3-week ago GIT, everything works ok. I use 3ds models exported from 3dmax without texture dependencies. My model consists of multiple objects.

I’m having the same problem as well. I updated to the latest player, playerglobal.swc, and github but no go on 3ds files

Excellent - it’s not just me then! I’ll keep working on my non-3DS stuff until this gets resolved.

Please supply us with the 3DS files that are not working, and we can have a look. There is no way of knowing from your code what goes wrong.

Sure, model in attachment.
When i change all source folders to new ones exept “loaders” it keeps working fine, but when i update “loaders” nothing shows - Resourse.complete dispatches with 0 children, Asset.complete is not dispatching at all.

the 3ds files I tried are the ones in my F-16 demo that Rob put in the demo reel so I know they are good. I’m using the exact same AssetLibrary code approach that wagster posted

Sure Richard, I’ve tried these four:

Thanks!

I’m having a problem loading a 3ds file as well.
I have no idea why its doing it…
I make the smallest difference in the model, and export it, then it doesn’t work.

For me the events get called as if everything went smoothly, but the LoaderEvent.LOAD_ERROR event also gets called.

Could anyone help me out?

preFab is a great way to confirm first off whether the model is OK so I’d suggest testing that way as well. There is clearly some kind of 3ds bug happening though since the new player hit

The 3D file works with everything else.
I guess I’ll just have to wait until its fixed with Away3D 4…
Please try to fix it quickly!
Thanks a lot!

Here is a model I can’t get texture to load to. If someone could test it and let me know what I am doing wrong. It does load fine in prefab, and I can texture it there, but not in away3d4 with flash 11. Thanks for anyone that can help.

There is a known issue with the LoaderEvent.RESOURCE_COMPLETE. It may in some cases return a null object event.currentTarget. Occurs often with low polys models, the event seams to be triggered too early. It seams, not saying that is the reason. But there is a fix if you set a AssetEvent.MESH_COMPLETE you will get the resource every time. You will have to add a switch and test on names if you have more meshes in there.

Finally if this fails too, try to export without map(s), embed it/them instead. Another issue occurs with relative url’s. The code adds an extra “/” causing a loading failure. To make sure this is not the case, make sure you set a LoaderEvent.LOAD_ERROR. All these will be fixed in comming days.

Just wondering since the low poly seems to be part of my issue How many polys does my model need before it is no longer a issue? I tried using AssetEvent.MESH_COMPLETE, but it does not seem to change loading problem for me at least. Thanks for all your hard work.

The extra “/” thing I noticed.

Checking for different events didn’t help…

I hope you guys get this fixed soon!
Thanks a lot.
