Title: How to set texture to object material
Post by: jaychang0917 on April 05, 2017, 09:42:51 am

Suppose my model is a composite of objects, and each object contains few materials, I need to map different texture for each material.

I tried to print the name, i can't get the material name but object name. How can I get the material name of each object?

Code: [Select]

for (Animated3D o : skinnedGroup) {
    System.out.println("name:" + o.getName());
    o.build();
    o.discardMeshData();
}
// output
name:headMesh_triangles
name:headMesh_triangles
name:headMesh_triangles
name:headMesh_triangles
name:headMesh_triangles
name:headMesh_triangles
name:headMesh_triangles
name:headMesh_triangles
name:headMesh_triangles
name:headMesh_triangles
name:Cover_LMesh_triangles
name:Cover_LMesh_triangles
name:Cover_RMesh_triangles
...

you cannot I believe. materials and texture information is not passed to Bones during export-import process. texture coordinates are passed though.

in this case, you can for example bake the materials into a texture and assign that texture to your Animated3D's

video not appearing part may also related to a thread synchronization issue. in particular if you dont consume a video frame new update never arrives (as far as I remember)

i tried to set the texture by Animated3D index instead of name, seems work.

Code: [Select]

animatedGroup.get(0).setTexture("head");
animatedGroup.get(1).setTexture("headTop");
animatedGroup.get(2).setTexture("head");
...

raft, I found that the imported model is not rendered correctly. If the geometry contains multiple elements, it seems only render the first element. Do you have any idea?

which pipeline are you using, Collada or Ogre3D?

are you sure it's exported correctly?

I am using Collada.

I found that the model is rendered correctly using the ProceduralAnimationBonesSample, is it the jpct-ae problem?

interesting, might be jpct-ae

Almost all code are the same for desktop and android version except the FrameBuffer object creation.

For android (jpct-ae)

Code: [Select]

frameBuffer = new FrameBuffer(width, height);

For desktop (jpct)

Code: [Select]

frameBuffer = new FrameBuffer(width, height, FrameBuffer.SAMPLINGMODE_NORMAL);

So what approach can i take to solve this problem?

It doesn't seem appropriate now that I've read the rest of the thread, but it's useful to point out the following max script that I use to create texture atlases (it fails 30% of the time but it's still very useful when it works): http://www.scriptspot.com/3ds-max/scripts/texture-atlas-generator (http://www.scriptspot.com/3ds-max/scripts/texture-atlas-generator)
