So for context, I'm using AR core in Unity to build an augmented reality experience for my job. I've made a version of this using adobe Aero and I'm using unity in order to get it available for use with Android. Anyway, how I've been switching between scenes in aero is through use of a flat, PNG button that says next scene, making everything disappear and the next scene appear. So far, in unity, I haven't gotten the PNG's to import into the scene.
I've been doing research and I loosely know that in a 3D space a flat image becomes a 'sprite' but I'm not sure if I'm importing it incorrectly or using the wrong format, and so far all the resources I consulted only talks about sprites in a 2D setup. not 3D or AR as I am. Any ideas or suggestions are welcome.

I'm using unity 2018.4.14f1 personal (I don't use 2019 or 2020 because it lags my computer)
I'm using the Unity Standard Assets Player Prefab and Cinemachine Freelook for the camera. I have some water, and when my player walks into it, its fine. However, when the camera comes into the water, it stops rendering the water. Is there anyway I can fix it?
Update: I've somewhat got it working, however its hollow when your inside. Is there anyway to fix that?

(I'm quite a noob so if you need any screenshots please ask.)
The problem here is that the water will only rendered when looking from the outside as the normalized are modeled so. The program renders outs objects that it thinks is not in view. You can load the model into a 3d program and then copy and invert the model to allow your camera to see the water, or I believe there are some shader option to stop this optimization. You can also look in this Reddit thread.
I just went through a Blender tutorial (https://www.youtube.com/watch?v=UgmJsLcLXUI) that showed how to create a morphing particle system animation in Blender. He ended up creating 2 layers, with a separate example on each.
The particle system animation, when played on the Timeline, looks very cool in Blender. Now I'm wondering how, or if I even can, to properly bring it into Unity and basically turn it into particles within Unity. I was hoping i'd be able to create a Shuriken Particle System in Unity, using the exported Blender file as the mesh shape.
But anyway, I've tried like 4 different ways of exporting from Blender and importing to Unity, and I can't get Unity to recognize it the way I need it to. Any tips on how to make this process work, or if it's even possible to ultimately do what I'm trying to do re: the title?
I am interested in building virtual reality applications and I am at beginner level.
I imported a FBX file of Airplane and imported it in Unity,
Upon linking the animation in Unity and building it onto my Mobile, I see a 2D version of the model. How should I convert it into virtual reality application.
Below is a snalshot of the file. The aiation is also fairly simple, one plane takes off and flies for sometime before landing.
Below is a snapshot of the Game Console
So inshort the question is how do I convert this into a 3D mode so that I can use it as a virtual reality Application.
Thank you
That is 3D mode.
Making a VR application isn't done at the push of a button
Start here:
Read about VR in unity
It seems like you are a new Unity user. If so do this first:
Depending on what you want to do in your application you should look into the Unity Documentation and read about:
Basics
Cameras
Creating Gameplay
Animation
If you at some point feel you don't understand these links, you may need to take another step back and start off by checking out the official tutorials
Just save your .blend file in the Unity's Assets folder.
Look at the documentation for more informations
I have a scene in cinema 4d, with a camera that moves through the scene. I was hoping that I could just import the entire cinema4d file into unity3d and I could just magically press play, and the scene would just.. work--camera movement and all.
Well, maybe life is not that easy. Is it even possible to import a camera from cinema into unity?
It would be nice not to have to re-program the camera in unity.
Do I have any options?
The answer is no, there is no "concept of" a camera path you can import to Unity. There is nothing whatsoever like that. (Don't forget, it's a game engine - not an animation or "filmmaking" system really.)
Fortunately this is a relatively common problem.
The solution is just that you put "any old thing" (say, a white cube) there and import that animation. Then in Unity it's trivial to just child the camera to that "marker".
You can google many examples,
http://answers.unity3d.com/answers/20413/view.html
try googling say "import camera move to Unity3d"
BTW I'm sure you're aware of this .. "Unity does not import Point Level Animations (PLA) at the moment. Use Bone-based animations instead." Doco
Another more hackish workaround;
I have once made a scene in Cinema4D which I wanted to use in Unity3d. I ended up employing MOCCA to export the camera's positions and rotation-values on it's keyframes and ended up using coding on the Unity end of things to animate the camera, based on an xml-file.
However, not having used Cinema4D in a bit; I can't remember for sure if MOCCA is still available? If memory serves me right it got replaced with something...
I have models created with 3D Studio Max.
When I save as .FBX and import into Unity 3D they become grey. What's the reason of this and how can i solve it?
Also i have huge troubles with performance of model on mobile. What's the best approach to get app faster?

I've gone through the same issue when importing the following 3D Data Visualization model
The model was created using Cinema4D and exported as .fbx.
When i imported into Unity using drag and drop, I got the following result
As we can see from looking at the Inspector (image above) the material is grey and can't be edited, the textures were not imported. The materials of the default assets cannot directly be edited but there's a way to go around it.
I've created a new material (right click in assets > Create > Material)
Gave it a new name (green) and changed Albedo to green.
And dragged the material to the cube
The end result now looks like expected
Also i have huge troubles with performance of model on mobile. What's the best approach to get app faster?
It can be tricky to develop mobile VR apps but the game window has an info panel that displays useful live information (Use Stats button in the Game window to enable it)
There we can read how many SetPass calls, Batches and polygons are being drawn. Aim for 50 SetPass calls, that's a good number accordingly to Unity experts.
About optimizing performance, some very good developers already explain in detail how to optimize your scenes. I suggest the following links
Understanding VR Performance
Profiler window
1) all models gray- this means the texture was lost in the import. You can create materials and drag them onto the mesh. But Unity can import your max files directly, you dont have to export to .fbx. Maybe if you try that your textures and materials will be setup automatically.
2) performance on mobile- can be various causes. maybe too much detail in your models. Or more likely too many drawcalls, or maybe too heavy cpu upsage . hard to say. the unity docs have pointers on optimizing for mobile.
