Just a short note on how to enable zooming in and out with your Apple magic mouse in Blender 2.6.7. After I updated to the newest version mouse scrolling in UV editor results in Pan View, definitely not what I prefer. Maybe this is because I defined Ctrl + mouse wheel system wide for zooming the screen.

After wasting a lot of time when flipping Blender animations made for left side to the right and vice versa, I decided to write an add-on doing it automatically. Have you ever been annoyed about copy & paste X-flipped pose frame by frame? See the video tutorial below how to solve this problem in your project.
Blender allows you to copy poses and paste them as X-flipped Pose within one frame provided your bone names conform to the naming convention. This is nice but when animating a run cycle and you have set up the first half of it, you don't want to copy and paste frame by frame.
Doing game development for mobile devices often leads to situations where you feel like programming in the 1990s again. Unacceptable drops in frame rate, low memory warnings and other performance hassle could be very painful and cost you days and weeks.
So I am going to describe the basic techniques for performance analysis and how to use the profilers for Unity3D pro on iOS including some hints how to tweak them. A sample case detecting spontaneous frame rate drops is given at the end.
I just came across the problem of handling disabling and reenabling the idle timer within an iPhone app. Especially when running the app includes longer intervals without touch input activity, the system might turn off the screen during the game. Here is a small piece of code how to manage this.
I was curious about the impact of several Mathf functions when running an app on iPhone. So I decided to make some measurements on iPhone 5 and iPhone 4. Here are the results.
There are a couple of resources out there describing how to set up basically Unity3D with Subversion. In this posting I describe the special situation when developing for iPhone i.e. which XCode specific files should be under version control, how to have different versions in parallel and how to get off cheaply on major Unity3D version updates.
Although I found plenty of information and really awesome tutorials about rigging, skinning and animation, I ran into some problems on the way to my first animation. So in this posting I list all my problems and the solutions / workarounds I found for them.
Using Unity's ragdoll wizard leads to the problem that the prefab connection to the character model is broken. That means after a change of the model in your 3D software yo have to perform the whole procedure again. To avoid this I wrote an open source code generator that saves all ragdoll components in a C# factory class which you can invoke at runtime.
OK we've got the excellent Subversion docs and man bash and if you are the bash guru and Subversion expert, you know very well how to combine these to get every job done. All others struggling with whatever is beyond cd and ls in terminal app but don't want to pay for SmartSVN or whatever will get some tips and tricks. Focus of this article is not the 500th description of the most important commands from both worlds. Instead I am going to show you how to quickly improve your day to day tasks without having to know too much about the background.
OK you have got a high polygon Blender model with let's say 10-20k vertices, maybe bought from one of the 3D model shops out there, and now this needs to be decimated because processing of animations takes ages in our game. How can we do this in Blender 2.5x/2.6x?
is a powerful content management system well suited for running almost every kind of web site. And it is open source, free of charge although to get the most out of it, you sometimes have to buy some commercial extensions. In this article I will describe some of the basic setup of this site from an architectural point of view. Thus this article contains considerations about the mandatory features and gives some hints to implement them, but it is not a step by step tutorial.
I am no Blender expert (not yet) and I started working with Unity3D just a few months ago. Setting up the work flow of importing 3D models created with Blender was a bit painful. So if you are about to start with Blender and Unity3D, this little checklist might be useful for you.
I love this site :-)
There are zillions of web sites where you can find useful questions & answers. From time to time I started to participate at some sites, but it never lasted more than a few postings. When I was new in iPhone programming, I noticed that most of the really helpful answers are at stackoverflow.com
Deploying for iPhone from Unity3D can be a little bit tricky, especially when customised code or 3rd party libraries are part of the project. So I decided to publish my own little check list and some hopefully useful information. In general I recommend the newest Unity3D version you can get (3.4 at time of writing) because there were some problems in Unity3D 3.3 leading to a bunch of errors and warnings.
