Working with COLLADA or FBX

[QKnows]

Hello, I try to import some complex scene (gvrContext.loadModel("scene.fbx")) and I have no so much success. What's the best way to work with GVRModelSceneObject, which fbx or COLLADA format is supported, is there some specification available? Some tip which application should be used, to work with fbx or Collada files? All formats I tried have some issue with shader or something else, each scene doesn't look nice as it should. So I would be really thankful for some idea...

[NolaDonato]

We do support Collada and FBX but not everything in those file formats. Would it be possible for you to send us a test asset showing the problem? Maybe we can figure out what is in your file that does not import correctly.

@QKnows Attaching some logs might help us identify the problem.

[QKnows]

Hello, I attached a log from my application, try to load an fbx file, which have converted with the autodesk converter, I read about the converter in another issue.

The FBX file has the following header: ; FBX 7.3.0 project file ; Copyright (C) 1997-2010 Autodesk Inc. and/or its licensors. ; All rights reserved. ; ----------------------------------------------------

I can't provide that scene file, because it has some copyright issues.

I tried many exports from DAZ 3D, and the most scenes [just simple scene, sphere with a mapped texture works] doesn't work because of some shader problems.

So any (complex-)scene which has been created with DAZ 3D and some lights will be shown wrong in GearVR, I am not sure about copyright of provided DAZ 3D stuff - so I am afraid to share it here...

Ok, I see couple of these which is abnormal:

07-21 17:01:49.883 718-772/com.test.app.scene.player I/gvrf: !! 0xd7e0c640 Prog Id -- -1 
07-21 17:01:49.883 718-772/com.test.app.scene.player I/gvrf: after renderMesh::renderMaterialShader() glError (0x501)

We will look into it. Thank you for letting us know.

[QKnows]

Hello @liaxim - are you still working on that isseu? Or should I try to find another way to use 3D scenes?

[liaxim]

We have been fixing model loading bugs. I will have somebody double-check the current status when trying to import models from DAZ 3D.

[QKnows]

Thank you @liaxim for still working on that issue...

Hi All,

I used the already provided 3D model of Dragon from DAZ studio and exported as FBX 2011 and try to load using GearVRf. The result is crash:

In case of model exported as OBJ file removing bump map images will load the model.

[deepak-rawat]

@QKnows you can export the scene in OBJ file format with supported texture format (tif is not supported) and GearVRf will load those models. Meanwhile we will look into FBX and COLLADA. Let us know if you face any other issue.

[deepak-rawat]

@QKnows You can use FBX file. I tested with 2012 ASCII format. For now the limitations are bone numbers must be less than 60 and textures exported to folder (no embedded texture). Let us know if you face any issue.

[QKnows]

@deepakrawat22 I still have problems loading a model, is it right to load the model like that:

GVRModelSceneObject so = gvrContext.loadModel("model.fbx");

The RenderData is always null

so.getRenderData() is that correct?

[NolaDonato]

The GVRModelSceneObject returned by loadModel will not have a GVRRenderData component but on of its children may. If you want to access all the GVRRenderData components you can do this:

ArrayList renderDatas = sceneObj.getAllComponents(GVRRenderData.getComponentType())

This will give you all of the GVRRenderData components in the entire model.

[roshanch]

@QKnows have you tried the above approach? Can we close this issue?

[QKnows]

I have tried to load scenes without success - I planned to make a Framework update and test again, but since the last update my app isn't not working anymore (issue #850)

[roshanch]

@liaxim can help you with this.

[deepak-rawat]

@roshanch I was able to import few models from DAZ studio. Will check other models as well. Also a lot of models are imported with unsupported texture file so not able to render them.
