i have a few quick questions:
background:
i want to display a in-code generated html with UniWebView in my game. Mostly works nicely until i try to display local images (from my unity-resources)
the images are in my "Resources" folder (and used elsewhere in the project also)
my goal to support Android/iOS/Windows environments with the game
Q1: can i display images from "Resources"? this would be the best if i could
Q2: do i need to move all my assets into the "StreamingAssets" folder and access from there? if so, can "StreamingAssets" folder be under "Resources" folder? like this: "Resources/StreamingAssets"? If so please confirm that i can use them as unity resource for unity components AND also streamable assets for UniWebView in the same time?
thanks!

I'm building an app that must visualize a large point cloud on HoloLens 1st gen. As performance is an issue wit large clouds, I'm using Potree, an octree that takes care that only a preset number of points from the cloud are rendered.
The solution works in the editor, but, you guessed it, not when deployed on HL.
The point cloud in the Potree format is a set of couple of .json and hundreds of .bin files stored in hundreds of subfolders following the octree structure, all of that stored within a single folder, and the path to this folder is accessed by the renderer at runtime. However, I don't know how to include this folder in the HL app. Using Resources doesn't work as it's not really a standard resource. I've seen Asset Bundle suggested elsewhere, but according to this post asset bundling doesn't work on HL.
Is there a way to simply put this complex file structure in an accessible directory on HoloLens?
I feel completely stuck here and any help would be much appreciated.
Some of the things I've tried:
Keijiro Pcx doesn't work here. If rendered as single pixels, points cannot be seen in AR, and if rendered as meshes, the performance is abysmal (which led me to a conclusion octree structure should be used)
the solution here shows how to load one .xml file, but I have hundreds of files so I don't think it would work for me
similarly, this post deals with one .obj file
Unity 2019.4
HoloLens 1st gen
For anyone stumbling upon this - I ended up using Unity StreamingAssets and accessing the folder with Application.streamingAssetsPath - works beautifully!
Using pcx needs to be adjusted to binocular rendering in publishing settings. Please uncheck "Enable Depth Buffer Sharing" in XR Settings, and change "Single Pass" to "Multi Pass", as shown in the figure.enter image description here
I am trying to create custom radio tracks in my Unity game, and I want the user to be able to place audio files in a directory like My Documents/My Games/Unity Game/Custom Sounds/ . Then I want Unity to put all audio clips from this folder into an array for me to use in my code. I have searched but cannot find anything about loading a file you don't know the exact path of, or how many there will be
From #Eddge:
Yes, use the WWW class. docs.unity3d.com/ScriptReference/WWW-audioClip.html for the URL use file:// then the path of the file, it is important to note that unity only supports some music file formats, depending on the platform. So for example .mp3 will not work if building for windows desktop
I'm just starting to create a controller for use with Airconsole. I'd like it to be somewhat complicated and will be using Angular to create different pages.
In Unity, I can drag in a controller.html file. However, I've been getting resource not found errors when I try to access say controller.js or controller.css. How can I upload multliple files to the Airconsole host? Is there a general pattern used by other games?
So far I'm considering
hosting my app separately and just redirecting to my separate web page. This seems to give errors in the emulator though.
Compiling the entire app into just one HTML file.. Not sure how to get these entirely into one file. When I run ng build I get a smaller dist compiled file, but it still consists of several smaller files. Will try dragging that into Unity and trying again. But dragging the entire Angular project inside Unity felt like a really bad idea..
Link to files hosted on separate pages but still have the uploaded HTML file do something.. But not sure how much I need to do here vs how much I can move to other files that I host.
You can create your controller using controller.html with Angular (1?!), have different pages (e.g. via ng-include and the angular routing module) and upload everything to AirConsole (developers).
By using ng-include you can have multiple .html views you dynamically load into the controller.html.
I once wrote an example app for AirConsole and Angular:
https://github.com/francois-n-dream/airconsole-angular-phaser
Just think of it as if you would make a (mobile) website which in addition uses the AirConsole API for device communication.
My basic "how to include other files" question was answered well by another question: How to include js and css.
For the more generic question of working with Angular, I still haven't quite figured it out. But what I'm doing at the moment:
I have an Angular project outside of Unity. I run ng build to compile everything into a folder dist. Then two options work:
Deploy the dist folder to static file hosting and change index.html's relative links to point to the separately hosted files with <base href="https://cloudfilehosting/airconsole-host/">
OR
Copy the dist folder into Unity's Assets/WebGLTemplates/AirConsole folder.
I'd like to load "dynamic" assets (in particular, FBX files) that are located outside of a "Resources" folder so that the user can add/remove/modify files with no need to re-build the project.
To make those files easily accessible for the user in different kinds of devices (target platforms are desktop/android/ios), it seems reasonable to use either Application.persistentDataPath or Application.streamingAssetsPath.
Now the problem is: How do I load them (as proper Unity objects) ?
This obviously can't be done via Resources.Load() as they are outside a "Resources" folder.
Using WWW, retrieving the files should be easy and it could actually work for some types of files (e.g. textures, see http://docs.unity3d.com/ScriptReference/WWW-texture.html) but I cannot see a way to load something else.
The idea is that I'd like to be able to use those loaded objects like so:
(GameObject) Instantiate(loadedObject, new Vector3(0, 0, 0), Quaternion.identity);
I would really appreciate your help (preferrably with a solution that does not require a "pro license").
I know two options that you can try to use in this case:
Build an asset bundle for each dynamic asset you want to load, but this seems not really what you desire, because the user still have to use Unity3d to generate the asset bundle.
Use an custom 3d model loader, like described in this post, seems the best fit for your case.
I want to using the Unity3d framework for a project in which I have create a walkthrough. But the client want it to be dynamic.
We would be getting the final fbx file from 3DMax which when added to a particular folder a walkthrough should be created automatically. I went through the help files on Unity3D site but did not find any documentation as to how use the Unity3D framework programmatically.
Can anyone please let me know how can it be done? Even if link is provided for the resource it would help us.
Unity 3D has a built in way to load models at runtime, but this should be done using a Resources folder (Resources.Load()) or using a Asset Bundles (AssetBundle.Load()) as described here: http://docs.unity3d.com/Documentation/Manual/LoadingResourcesatRuntime.html
These two methods are performed inside the Unity editor and your need is load any arbitrary 3D model file at runtime, for this case you will need a plugin. The only one that I know is ObjReader.
