Will this work with Kits and the new SDK? Yes, you can use all the tools together if you'd like. We're trying to develop them to work seamlessly together.
Will this even work with the old SDK? Yes, while we still support the old SDK. You can edit your world and set the "Layout > Overrides" like before. Just be aware that people entering your world will be loading a browser and all the caveats that come with that.
Does it support particle effects?
Can I get spatialized audio? Not right now but you can place audio sources to play in localized areas.
Does baked lighting work? Yes, but your lights have to be set to "baked" and not "mixed"
Does global illumination work? Yes
Do you always have to reset the World? Yes. We have to reload the Unity Asset Bundles every time.
Can I use my own custom materials and shaders?
Can I upload to one platform only? Yes, using the tool. However, people who are on Android will not see anything in your World until you upload the scene for their platform.
Are scripts allowed? No, for security reasons we can't allow scripts or script references. If your upload contains scripts or script references, it will be rejected. If you World needs scripting, take a look at the new SDK.
How big of a scene can I upload? We suggest you start small and be mindful of people in Altspace who don't have monster PCs. That said, we've had games bring in their maps for live streams (e.g. Onward, a VR shooter game)
Do I have to host the scene files? No, Altspace is serving up the files once you upload them
Are shadows allowed? Yes
How quickly can I iterate using the Uploader? If you're already in your World, you can press Upload in the Uploader, reset your World, and see the updated scene in as little as 10 seconds. Typically, you'll see loops of 30 seconds to a few minutes depending on the complexity of your scene. Have a drink, you deserve it for being a World-Builder!
Where do I get 3D models? Sketchfab, Sketchup, Google Poly, Minecraft, Unity Asset Store, etc.
Does it support animations?
How can I setup spatial audio? Import the wav file of choice, create an empty game object in the scene and select this object. Drag and drop your imported sound to the inspector of the object and it will create an audio source. Aftwards adjust the volume to no more than .5, change the spacial blend to 3D, and adjust the min and Max distance to create a proper area of sound. This is displayed as sphere like colliders by defualt. To get a true drop off you will need to adjust the drop off curve to your liking.

How come I'm seeing cross-eyed / weirdness? Sometimes the Uploader does not successfully override your rendering settings. "Go to Edit > Project Settings > Player". Make sure "XR Settings > Virtual Reality Supported" is checked and "Stereo Rendering Method" is "Single Pass" or "Single Pass (Preview)" for both PC and Android (click the robot icon). Afterwards build + upload again and reset your World.
