How to Fix the Unity “Lighting Data Asset..” Error on Opening a Scene

Unity LogoI opened a Unity project on another computer, and got a message that the lighting in my scene was built with a different version of Unity than I was using. I searched the forums and Answer section but found nothing useful. I was using version Unity 5.4.0b17 on my laptop, and opened it using version 5.4.0b22-HTP (for HoloLens development) on my desktop. The scene opened up without any details, just a yellow screen.

I was going through the Tanks tutorial and luckily the instructor had mentioned “Auto Build”. Here’s now to solve it.

Hands-on Review and FAQ’s of Microsoft HoloLens

Microsoft HoloLensSo my Microsoft HoloLens arrived this week and I haven’t been this excited since I got my first Nintendo. I placed the order on Thursday, and it was at my door, straight from China, by Tuesday. I was a part of the 3rd wave (developers are receiving the device in waves as they become available) and was scheduled to get mine around September/October. This was an awesome surprise!

My house now looks like something out of a video game with holograms hanging around everywhere and after using it for a few days it’s starting to dawn on me just how revolutionary this is.

How to fix VMware No Disk Error at Launch

logo-vmwareAfter testing how to convert VMware virtual machines to Microsoft Hyper-V, I ended up getting a very annoying message when starting VMware Workstation.

Issue:

You are getting an annoying popup that VMware can’t find some non-existent disk and you have to click “Continue” until it goes away every time you launch VMware Workstation.

Solution

  1. Edit the ‘favorites.vmls’ in your roaming directory:

    C:\Users\[your_user_name]\AppData\Roaming\VMware\

  2. Find the bad entry and delete all of the references to the missing image, then save it.The file contents look like this:
vmlist1.config = "D:\vm\W7\Windows 7 Professional.vmx"
vmlist1.DisplayName = " Windows 7 Professional "
vmlist1.ParentID = "0"
vmlist1.ItemID = "1"
vmlist1.SeqID = "0"
vmlist1.VmPath = "/vm/|75u5633deg3tt8f797r/"

How to Update the Date and Time in Ubuntu with NTP

Ubuntu LogoI fired up a Virtual Machine that I’d created months ago to update a Let’s Encrypt certificate and noticed that the date showed as January, but it was actually April. This particular VM didn’t have VMWare Tools installed [yet] so it wasn’t picking up on the host’s time. It’s no problem to fix, just update the time using NTP.

Issue

Updating your system’s with NTPDate throws the error, bind() fails: Permission denied, or “The NTP socket is in use, exiting”.

Solution

  1. Install NTPDdate

sudo apt-get install ntp

sudo apt-get install ntpdate

  1. Stop the NTP service

sudo service ntp stop

  1. Update the date and time

sudo ntpdate time.nist.gov

Explanation

Error: bind() fails: Permission denied

You need to execute the command using sudo.

Error: The NTP socket is in use, exiting

The reason you get the socket error is because NTP is already using that socket. You need to stop the process, force an update, then restart the daemon.

How to Fix the Missing Assembly Reference for Microsoft Hololens Emulator in Unity

logo-unityI wanted to try out the HoloLens emulator while waiting for my chance to purchase the physical unit, but was stopped dead in my tracks with some setup issues. Here’s how I fixed the issue.

Issue

When you click “Play” in Unity, you receive an error like, “Assets/Holograms/Support/Fitbox/Fitbox.cs(2,2): error CS0234: The type or namespace name ‘WSA’ does not exist in the namespace ‘UnityEngine.VR’. Are you missing an assembly reference?” Your first warning was when you opened the tutorial files and you received this message that you ignored:

There are actually a couple things you may need to fix.

Solution

First, you need the special technical preview of the Unity editor, not your regular editor. Secondly, you’ll need to head to GitHub and download the updated version of the Unity project. Microsoft created the tutorial with an old version of Unity. The original files on the Microsoft Developer Hololens Tutorial are old. You’ll need the latest version of the Unity editor and project files. The special version won’t overwrite your current editor. You can have both installed at the same time.

Steps

  1. Download and install the Unity editor for Hololens.
  2. Install the UWP Runtime.
  3. Download https://github.com/Microsoft/HolographicAcademy/tree/Holograms-101
  4. Unzip the file
  5. Copy the “Assets” & “ProjectSettings” folder into your Origami folder. It should overwrite the existing “Assets” & “ProjectSettings” folders

How to Fix Lenovo Yoga Pro 2 Screen Flickering Issue in Windows 10

Windows 10 LogoI noted a few issues after upgrading dozens of Yoga Pro 2’s to Windows 8.1 Pro and Windows 10. They can easily be easily fixed, but you have to know what you’re looking for. During the upgrade process, the Lenovo’s gave me less issues than my Dell XPS, which completely froze during the process. Two of the more irritating upgrade problems were 1) the screen flickering at random times. 2) the laptop being sluggish and unusable after waking up from sleep mode. Here’s how I fixed the first issue.

Issue

Screen flickers randomly after upgrading to Windows 10.

Solution
