Just get the obj visible first, I’ve stripped down some code you can use, just replace the obj reference.

Ok. I copied the code and changed the path to my 3d object, and ran the code. No errors, just a black screen.

If the 3d object isnt loading, could it be corrupt? May it need to be exported (via 3dsmax) again? In the directory exists the .obj file and .mtl file (from the export).

Traces in onAssetComplete() and onFullyLoaded() come through?

Yes, traces work.
BUT, I think I found the problem! I googled the method for uploading the files. Im uploading from my server (dedicated hosting).
Turns out my server was sending an error and restricting the >mimeType = “application/octet-stream”<. By default, it didnt allow streaming! I have to install a media server to my server and it should fix the issue right up.
I just spoke to tech support for my host, and they confirmed this is a common issue and referred me to Red5, an open source media server.
Ill attempt to install it over the next few days and update this thread.
Thanks again Donny.

Hi all, especially Donny!
Ok, here’s the update…
I installed Flash Media Server. Embedding and using a stream is working.
Here’s the new issue: Now that the streaming is allowed, the as3 script attempts to embed the obj, but fails with this error…
Error 3684 Invalid bitmapData: Width and height must be power of 2 and cannot exceed 2048
The problem is that all the texctures DONT exceed 2048 and are all divisible by 2 (example, 1012x1012, 512x512).
My 3D object was made via 3dsMax 2012, exported with .obj and .mtl files.
What could be causing it? I spent an entire day, literally, trying to see and I cant fix it! Please help.

1012 is not power of 2. 1024 is.

Fabrice Closier - 17 April 2012 01:23 PM 1012 is not power of 2. 1024 is.
Aha! Powers of two, not multiples!
2,4,8,16,32,64,128,256, 512,1024, 2048
Ok. All errors have ceased! The object loads into the scene!
This is how it looks:
How it Looks Now
This is how I need it to look:
How it needs to look
So the new question is… how to get the textures to look like they should?
Side Questions:
Why does it look so weird?
Whats going on with the dark area?

Fyi, I really appreciate the help. If I can get one object from 3dsMax to flash, successfully, looking as it should, it makes me learn the process, make adjustments, and understand Away3D. Your help is invaluable.

There are lots of possible causes, but as your first png is poststamp sized: it doesn’t say much.
If your obj data is triangulated, propperly mapped, and holding normals pointing in teh right direction. You should see same as on your second rendering. You might need to set the repeat to some materials if you have tiled, and probably define/set some lights/lightpickers to get some “volume”.
About your “dark area’s”. You do not define your camera.lens.near & camera.lens.far in your code. It uses the default values. Your model probably doesn’t fit in between these values.

Ok, I remade the building, but there’s still a problem.
It goes back to the original issue (title of this thread), loading multiple textures.
There are 8 textures being used in the object. But only one of them appear (the grey brick).
This is how it looks in flash:

This is how it should look:

you need to build you model so that it has one material per mesh. I guess you export a multiple material mesh.

The mesh I showed above is multi-materialed exported mesh. :/
Is there anyway to have all textures show up, or is away3D limited to one texture per mesh?

Yes and no: yes there is a way, yes a mesh can in Away have multiple materials. No the parser isn’t ready for this. Tho, it would be handy if you would provide me the obj (offline) so I could take a closer look, be able to test and possibly implement this feature.
