Small Glitch Remains One last glitch to squash … On page/section > **[A new, community-hosted Unreal Engine Wiki](https://forums.unrealengine.com/t/a-new-community-hosted-unreal-engine-wiki/141494)** > > After over a year in maintenance mode, the official Unreal Engine Wiki is now permanently offline. These resources now live on a new community-run Unreal Engine Community Wiki — https://unrealcommunity.wiki/! You will be able to find content from... Under the “Unreal Engine4” heading it now says: “Unity uses a left handed coordinate system – where the vertical direction is usually represented by the +Z axis. Z axis up.” whereas is should say: “UE4 uses a left handed coordinate system – where the vertical direction is usually represented by the +Z axis. Z axis up.” In other words, as things stand, the text under both the “Unity3D” and “Unreal Engine4” headings mentions Unity, whereas the text under the “Unreal Engine4” heading should mention UE4. --- _[View the full topic](https://forums.unrealengine.com/t/two-coordinate-system-description-errors/33079)._
