The previously available "VBO
" (Vertex Buffer Objects
) Scene optimisation setting found in "File » Preferences » System
" is no longer available Blender 2.77 onward (subject to change) as the "VBO" property is now ON by default
. This means dense or vertex heavy meshes are (graphic memory) optimised regardless, Blender now shunts vertex data into graphics rather than main system memory by default rather than as an option.
Note: for older hardware this may mean being locked to Blender 2.76 or below because the feature relies on relatively up-to-date OpenGL support, typically not provided by older graphics hardware.
"VBO" setting available in "System" preferences in Blender 2.76.
"VBO" setting no longer available in "System" Preferences, Blender 2.77.

Corel Video Studio (Pro) won't run after Windows Update (For Feb/Mar 2016) has been run. Program also does not respond to being placed in Compatibility or other mode (right-click vstudio.exe, select "Compatibility"). The issue is caused by a number of updates to a Windows sub-system that essentially breaks a link in the necessary chain of events needed by Video Studio (Pro). Problem appears to affect Windows 7, Windows 8/8.1 and Windows 10 to a lesser degree.SolutionA 'HotFix' for Video Studio x7 or above is available from Corel here
For Video Studio x6 or below, or in instances where a HotFix cannot be utilised, try uninstalling the following Windows Update files;
For Video Studio (Pro) x7 and above uninstall 3126587
. For Video Studio x6 or below 3140410
may additionally need to be removed. Be sure to disable or 'hide' removed updates to prevent their re-install on reboot. For Windows 7, 8 and 8.1 updates this may necessitate switching Windows Update to 'manual'.
To see and uninstall Windows 7
- from "Control Panel
" select "Programs
" then under "Programs and Features
" click "View installed updates
To see and uninstall Windows 8/8.1
- from "Control Panel
" select "Programs
" then under "Programs and Features
" select "View installed updates
To see and uninstall Windows 10
- click "Start
", then the "Settings
" icon, then "Update & Security
". On the "Windows Update
" page select "Advanced Options
" bottom of the page, then on "View your update history
" on the following page. Click "Uninstall Updates
" top of the page to remove.
'fix' (which may be removed as a result) is available for Video Studio v6 or v5 users here
. Download "MUIHelper.zip
" and extract the contents. Copy the included file "MUIHelper.dll
" to the root directory of Video Studio (Pro), typically "Program Files/Corel/...
" - this overwrites an existing file of the same name, rename the original to archive it before copying over the new file. Video Studio should now start (note it may also be possible to install the previously removed updates).

Q: What is/does getting "FOX'ed" mean?
A: The term "FOX'ed" is a colloquialism to mean something has been 'taken-down' (often without warning) due to an infringement of Copyright pursuant receipt of Cease-and-Desist Notice. Although C&D Notices have a long history of being issued by Rights holders against others deemed to be misappropriating their Intellectual Property, it wasn't until 20th Century FOX issued a Take-down Notice on a Quake
, Alien Quake
, that the practice became more widely known, and subsequently referred to simply as "FOX'ed" - at the time the Alien Quake mod was capitalizing on the popularity of the "Alien" franchise, Property owned by FOX (primary factor), who were actively working on their own materials (secondary factor).
The Alien Quake project has been discontinued by 20th Century Fox. I received an email on April 11th, 1997, from a 20th Century Fox representative that ordered us to cease all activity. The Alien Quake project was using copyrighted material without permission and this makes Alien Quake an unauthorized and illegal production. Therefore, you are hereby ordered to remove all your Alien Quake files from your computer storage. You must also remove all references to Alien Quake from any WWW pages or internet sites you keep or maintain. All distribution of Alien Quake is illegal and you should know that the Alien Quake team are under obligation to report the name and URL of any distributor to 20th Century Fox. Please let us know if you know the URL of a distributor or potential distributor.
Thank you for your co-operation. [source]

Windows 10 appears to be randomly starting systems that have been shut-down without user input.
When a PC is shut-down from Windows 10 "Power" Start menu option ("Start » Power » Shut-down"), systems may restart on their own without user input (the user pressing the power button) anywhere from 30 minutes to several hours after the action. There may be no immediate or apparent reason(s) or causes for the computer to start-up unassisted.
There are potentially a number of reasons why a computer may boot and start-up unassisted.
If the PC successfully boots into Windows, to find out what initiated the boot call, from the "Command Prompt" ("Start » All apps » Windows System » Command Prompt" (right-click "Run as administrator") type "powercfg -lastwake". This will report the last item to initialise the computer and narrow down the device or service making the call.
Wake on LAN
If nothing is listed using "powercfg - lastwake" check to make sure the system is not set to "Wake on Lan". This may need to be done in both Windows 10 "Device Manager" and the systems BIOS (usually "F2" or "F10" to access on start-up). To access "Device Manager" click "Start » Settings » System » About (bottom-left menu) » Device Manager (bottom-right panel)". In Device Manager click the arrow (">") to the left of "Network adapters" to access the available hardware, right-click each entry in turn, select "Properties" and in their respective "Power Management" settings check that "Allow this device to wake the computer" is DISABLED (NO checkbox).
Additionally (and depending on availability, optionally), when checking the PCIe Lan properties (settings associated with a hardwired connection to the PC and not the Wireless device) click "Advanced" and scroll down the options shown to "Wake on Magic Packet"; set the "Value:" to "Disabled". Similarly for "Wake on pattern match"; set it to "Disabled". This essentially turns off 'wake' calls received over Lan.
If the above fail it may be Windows 10 "Fast Boot" ("Fast start-up") feature design is causing the issue (may also applicable to Windows 8.1). With this enabled when a system is shut-down from the Power menu options it does not fully power-off the machine but instead goes into a state similar to "Hibernation" (as opposed to "Sleep" mode) where certain features, services and devices are kept alive in memory to speed to the boot process - from a 'cold boot', all system devices have to be initialised which can take some time to do, "Fast Boot" relieves this by keeping some services in memory requiring fewer to be started on boot, thus reducing boot time. For "Fast Boot" to work, PC's are shut-down but not completely powered-off (so memory can remain active). This 'state' may result in systems randomly booting up without user input or prompting.
The "Fast Boot" ("Fast start-up") feature is part of Windows 10 "Power & sleep" settings and can be disabled (admin rights required). To access click "Start » Settings » System » Power & sleep (left menu)" then under "Related Settings" to the right click "Additional power settings". When "Power Options" opens click "Choose what the power buttons do" on the left then at the top of the page click "Change settings that are currently unavailable" (admin rights required). Scroll to the bottom of the page and under "Shut-down settings" disable "Turn on fast start-up (recommended)" (no checkbox).
Windows Update Reboots
It's also possible that apparent random system reboots are the result of Windows 10 automatically rebooting on schedule or after downloading and installing updates. Depending on the options set this cannot be fully disabled as Windows 10 (currently) downloads and installs updates automatically, rebooting from which can be delayed but not completely disabled (as is possible with Windows 7). To check, click "Settings » Update & security » Advanced options".

Typically Normal maps are converted into Bump or Height maps by simply opening the Normal map in an image editor and using some form of image desaturatation, either a filter or some other image process that swaps Normalised RGB colours for grey-scale values. This an incorrect approach to take because the variable colours present in normal maps do not represent the same light=height, dark=depth approach to creating the illusion of a three-dimensional surface. In other words, Normalised RGB colours and grey-scale tones are not interchangeable, they each represent completely different types of image data.Shown above a Normal map (left) has undergone a simple image desaturation process to 'convert' the image to a series of grey-scale tones (right). This causes issues however because the filter interprets lighter normalised colours, the pale blues and greens, as light-grey tones, which are in turn treated as 'height' elements of the resulting bumpmap (vice versa for darker colours)Solution
The Correct way to convert a Normal map into a grey-scale height or Bump map is to open the Normal into a proper Normal map processing application like nJob, or an image editor with a Normal map filter that can invert-process normal maps, and selecting the appropriate option to convert or reprocess 'Normal to Height' (in the case of nJob) or 'Normal to Bump'. This will desaturate the Normal map by correctly reinterpreting the three-dimensional structure represented by the Normalised RGB colours as simple Z-axis 'height
' and 'depth
' values.On the left is the original 'template' used to generate the normal map. On the right is the result of reprocessing the actual Normal map in nJob. Although there are minor differences between the two, they are far less significant than those resulting from simple desaturation. In-game especially, the difference is noticeableAdditional Resources
