In the SceneKit editor there's an option to bake the ambient occlusion. I've opened a model and clicked the bake button, but nothing is happening. The appearance of the object stays the same. Am I doing something wrong?
I'm using Xcode 9.0
One possibility is that your model is very complex (a few hundred thousand polygons) and the baking is running in the background, somehow failing or taking a long time. I sometimes did not get a message in Xcode that baking is running. You can look for a com.apple.dt.IDESceneKitEditor.Bakery process in activity monitor to see if it's doing anything.

I can't share much code because it's proprietary, but this is a bug that's been haunting me for awhile. We have SceneKit geometry added to the ARKit face node and displayed inside an ARSCNView. It works perfectly almost all of the time, but about 1 in 100 times, nothing shows up at all. The ARSession is running, and none of the parent nodes are set to hidden. Further, when I look at Debug Memory Graph function in Xcode, the geometry appears to be entirely visible there (and doesn't seem to be set to hidden). I can see all the nodes attached to the face node perfectly within the ARSCNView of the memory graph, but on the screen, nothing shows up. This has been an issue for multiple iOS versions, so it didn't just appear with a recent update.
Has anybody run into a similar problem, or does anybody have any ideas to look into? Is it an apple bug, or is there a timing issue I might not be aware of? It's been really hard to debug because of how infrequent it is, and I haven't found it discussed on any other forums (but point me in the right direction if there is a previous discussion). Thanks!
This is pretty common practice if AR tracking is poor for some reason.
I ran into a similar problem too. I think it's definitely a tracking error which arises due to the fault of the user of AR app. Sometimes, if you're using World Tracking Config in ARKit and track a surrounding environment offhandedly or if you are tracking under inappropriate conditions – you get a sloppy tracking data which results in situation when your World Grid/Axis may be unpredictably shifted aside and your model may fly away somewhere. If such a situation arises - look for your model somewhere nearby – maybe it’s behind you.
If you're using a gadget with a LiDAR, the aforementioned situation is almost impossible, but if you're using a gadget with no LiDAR you need thoroughly track your room. Also there must be good lighting conditions and high-contrast real-world objects with distinguishable non-repetitive textures.
Using Unity2D 2017.1.1f1, Tiled and Tiled2Unity, I exported a tiled map in Unity and there are no problems in the editor. I also tried it played maximised and there are no gaps present.
The problem shows up when the game is ran in iOS specifically iPhone 6s. There are noticeable gaps showing up.
Also, I also got the settings like this:
Any suggestions? Thanks..
(I'm the Tiled2Unity author)
Those gaps you are seeing are seams and they're common in Unity development when using tile or sprite sheets that "touch" each other. There are a number of ways that you can fix them described here.
However, these seams are fixed automatically with SuperTiled2Unity which is still free (or name your price) and is currently under soft release. Just be aware that all your Tiled files (TMX, TSX, textures) will need to be in Unity now (that's a good thing).
Dragging in all your files (with relative paths intact) to Unity should take care of the importing process for you.
I'm working on an application where the concept is that you can 'select' objects before actually placing them. So what I wanted to do was have some low quality objects on a shelf or something like it. When the user selects the object he then can tap to place the high quality version of the object in his area for further viewing.
I was wondering if it's possible with vuforia. I wanted to use this platform since it works well from what I could tell and it's cross platform (The application needs to be for android and the HoloLens).
I have set up the basic application where you can place a capsule in the area. Now I wanted to automatically place the (in this case capsule) once vuforia has detected a ground plane. From what I could see the plane finder has events that go off when an input is detected, but I couldn't find an event that goes off when the ground plane is detected. Is it still possible with vuforia? I know it's doable with the HoloLens, but I would like to know if it's possible for android or other mobile devices. I really don't know where to start/look for so I hope someone can point me in the right direction.
Let me know if I need to include more information!
The Vuforia PlaneFinderBehaviour (see doc here) has the event OnAutomaticHitTest which fires every frame a ground plane is detected.
So you can use it to automatically spawn an object.
You have to add your method in the On Automatic Hit Test instead of the On Interactive Hit Test list of the "Plane Finder":
I've heard that vuforia fusion, does not yet support ARCore (it supports ARKit) so it uses an internal implementation to simulate ARCore functionality, and they are waiting for a final release of ARCore to support it. Many users reported that their objects move even when they use an ARCore supported device.
I'm getting some weird effect on my terrain on iOS devices. In editor, it looks fine; on device it shows the light like the image below. The textures on the terrain are using the built in standard. I have verified that the metallic property is set to 0. I have Tried changing the material, the probes, all are not fixing the issue. Looking to see if anyone has experienced a similar issue or have a lead; I can work on a test. Using unity 5.3.5p5
I couldnt open this image but to my understanding you have a problem with terrain material.There is a several ways to solve this problem
1-) Be sure click the "Static" box on inspector window.
2-) Increase "Pixel light count" from Edit > Project Settings > Quality in normal time that variable is be arranged to 4 but I prefer 8 or 10 test it.
3-)Be sure about lights.Look their lighting Mode Realtime,Mixed and Baked They should be same for great scenes
After this tips if you scene is still broken delete terrain material and create a new terrain material.Good luck
If it's fine in editor then it might be an issue with your builds. Might try checking your quality settings to see if there are some lighting or shadow settings turned down. Go to Edit->Project settings->Quality and make sure the settings you have under the quality level and quality settings look appropriate for you build target (ios).
I would like to have some text appear and disappear in a puff of smoke effect in an iPhone game. For example, when someone scores points, I want to show the new points that were added. It should appear in a puff of smoke and disappear within a second or two.
How do I create that?
Have a look at Particle Designer from 71 Squared. It costs about $7.99 and includes easy code generation and integration. There are some pre-configured smoke effects available in the shared library.
http://particledesigner.71squared.com
You will most likely have kind of "cheap" effects using particles, but you'll have a good control over the animation (velocity, scaling, acceleration...).
Another way to go is to use multiple images of smoke and overlay them, then launch an UIView animation with random properties for rotating, scaling and timing.
