How to load ModelRenderable.builder() with multiple model?

I'm not sure how to load model into array for below code. All i can do it load a single model in a single ModelRenderable.builder(). but not for multiple model in same ModelRenderable.builder(). I appreciate if any one can help me with that.

ModelRenderable.builder()

ModelRenderable.builder()

ModelRenderable.builder()
.setSource(this, Uri.parse("https://unembittered-vector.000webhostapp.com/3dmodels/andy.sfb") )
.setRegistryId(1)
.build()
.thenAccept(renderable -> andyRenderable = renderable)
.exceptionally(
throwable ->
Toast toast =
Toast.makeText(this, "Unable to load andy renderable", Toast.LENGTH_LONG);
toast.setGravity(Gravity.CENTER, 0, 0);
toast.show();
return null;
);
ModelRenderable.builder()
.setSource(this, Uri.parse("https://unembittered-vector.000webhostapp.com/3dmodels/scene.sfb") )

.build()
.thenAccept(renderable -> andyRenderable1 = renderable)
.exceptionally(
throwable ->
Toast toast =
Toast.makeText(this, "Unable to load andy renderable", Toast.LENGTH_LONG);
toast.setGravity(Gravity.CENTER, 0, 0);
toast.show();
return null;
);
ModelRenderable.builder()
.setSource(this, Uri.parse("https://unembittered-vector.000webhostapp.com/3dmodels/shoes.sfb"))

.build()
.thenAccept(renderable -> andyRenderable2 = renderable)
.exceptionally(
throwable ->
Toast toast =
Toast.makeText(this, "Unable to load andy renderable", Toast.LENGTH_LONG);
toast.setGravity(Gravity.CENTER, 0, 0);
toast.show();
return null;
);


here andyrenderable is called to load into an anchor

Anchor anchor = hitResult.createAnchor();
AnchorNode anchorNode = new AnchorNode(anchor);
anchorNode.setParent(arFragment.getArSceneView().getScene());
TransformableNode andy = new TransformableNode(arFragment.getTransformationSystem());
andy.setParent(anchorNode);
andy.setRenderable(andyRenderable);

andy.select();


what i can do is , i can load model from Uri but i need to load model in same ModelRenderable.builder() as an array for other models too

ModelRenderable.builder()

Try this

List<RederableDefinition.Submesh> submeshes = new List<>;
submeshes.add(new RenderableDefinition.Submesh.setMaterial(Material material).setName(String name).setTriangleIndices(List<Integer> triangleIndices).build());

RenderableDefinition definition = new RenderableDefinition.setSubmeshes(submeshes).builder();
ModelRenderable.setSource(definition).build();


To be real I don't know exactly what expected from this, but Submeshes are the material (I hope what you mean by texture) and it is the only parameter that can be a list in a ModelRenderable.

A part from this your code look like you are trying to put 3 3D models on the same Model. Like draw 3 of them on the same place, would look weird and they would be one above another.
If you wanna give Andy shoes and maybe a background you need to make this already on a 3D models before or put then in different models.

Inspired by sceneform solarsystem sample, my untested solution would be:

String uris =
"https://unembittered-vector.000webhostapp.com/3dmodels/andy.sfb",
...
"https://unembittered-vector.000webhostapp.com/3dmodels/shoes.sfb"
;
CompletableFuture<ModelRenderable> mrs = new CompletableFuture<ModelRenderable>[uris.length];

for(int u = 0; u < uris.length; u++)
mrs[u] = ModelRenderable.builder().setSource(this, Uri.parse(uris[u])).build();

CompletableFuture.allOf(mrs).handle((notUsed, throwable) ->
if (throwable != null)
throwable.printStackTrace();
return null;


try
for(int m = 0; m < mrs.length; m++)
mrs[m].get(); // Do something, frist is andy.sfb, ..., last is shoes.sfb
catch (InterruptedException );


CompletableFuture.allOf(mrs)

ModelRenderable.builder()

changing texture in ModelRenderable using CompletableFuture

CompletableFuture<Texture> futureTexture = Texture.builder()
.setSource(this, Uri.parse(url))
.build();


and call futureTexture in ModelRendrable

ModelRenderable.builder()
.setSource(this, Uri.parse("https://unembittered-vector.000webhostapp.com/3dmodels/andy.sfb"))

.build()
//.thenAccept(renderable -> andyRenderable = renderable)

.thenAcceptBoth(futureTexture, (renderable, texture) ->
andyRenderable = renderable;

andyRenderable.getMaterial().setTexture("baseColor", texture);

)
.exceptionally(
throwable ->
Toast toast =
Toast.makeText(this, "Unable to load andy renderable", Toast.LENGTH_LONG);
toast.setGravity(Gravity.CENTER, 0, 0);
toast.show();
return null;
);


call into Transformable node

TransformableNode andy1 = new TransformableNode(arFragment.getTransformationSystem());
andy1.setParent(anchorNode);
andy1.setRenderable(andyRenderable);
andy1.select();
