How to Install Third-Party Code Plugins for Unreal Editor for Aximmetry

Author:

Prerequisites

  • Install the Epic Games Launcher and the Unreal Engine by following the instructions here.
    • Make sure to install the version of Unreal Engine that matches the version of Unreal Editor for Aximmetry. To find out which version you need, launch Unreal Editor for Aximmetry and click Help / About Unreal Editor. Only the first two components of the version number are relevant which looks like 4.26.
    • Optional: in Step 3 of Installing Unreal Engine click Options and disable all components except Engine Source. This saves several GBs of disk space.
  • Install Visual Studio 2019 by following the instructions here.
    • In Step 2 - Download Visual Studio: choose Visual Studio 2019 Community edition.
    • In Step 4 - Choose workloads: select Game Development with C++.
    • In Step 5 - Select Unreal Engine installer from the Games and Graphics section and Windows 10 SDK (10.0.19041.0) from the SDKs, libraries, and frameworks section.
    • Ignore Steps 6-8.

Installing Plugins

Download and install the plugin:

  • For marketplace plugins: Open the Epic Games Launcher and install the desired plugins from the Marketplace.
  • For manually downloaded plugins (for example from GitHub): Copy your plugin into the Marketplace plugin directory of the Unreal Engine (by default: "c:\Program Files\Epic Games\UE_4.xx\Engine\Plugins\Marketplace"). The path to the uplugin file should look like "...\Plugins\Marketplace\PluginName\PluginName.uplugin" (make sure there are no extra directories in the path).

Certain plugins require some additional steps. See the instructions listed below.

Open Unreal Editor for Aximmetry. In the Aximmetry menu, click Install Plugins. The first installation will take quite a long time, however, subsequent installations should be significantly faster.

Enable the plugins you want and restart the editor if needed.

Additional instructions for installing plugins

Most plugins can be installed by following the simple steps above, however certain plugins require some additional steps. If you want to use the plugins listed below, please complete these instructions before clicking Install Plugins in Unreal Editor for Aximmetry.

V-Ray For Unreal

  • In the Current Installation Parameters step click Customize.
  • Change Unreal Engine plugins location to [installation path]\Engine\Plugins\Marketplace. ([installation path] should point to the original Unreal Engine installation - do not change it to Unreal Editor for Aximmetry.)
  • Make sure the Install Chaos Cloud Client option is checked.
  • Finish the rest of the installation as usual.

Megascans

  • Install the plugin for the original Unreal Engine by following the instructions here.
  • The plugin can be installed either via the Quixel Bridge application or by manually downloading and unzipping it into the engine plugins directory. Both methods work fine, choose what you are more comfortable with.
  • Launch Unreal Editor for Aximmetry and start the plugin installation as described above.

Substance

Note: This plugin is known to crash the Unreal Editor in certain cases. This is a bug in the plugin so it happens with the vanilla Unreal Editor as well. The crash happens when certain meshes are sent to the Substance Painter. It seems to be caused by a material name collision. This can be worked around by moving the mesh asset to a different directory before clicking Send to Substance Painter.

Character Creator & iClone Auto Setup

  • Follow the official tutorial through steps 1 - 8.
  • In step 9, copy the Content directory into your project as instructed. Do not copy the Plugins directory into your project. Instead, copy it to the Engine\Plugins\Marketplace directory of the original Unreal Engine.
  • Launch Unreal Editor for Aximmetry and install the plugins as described above.
  • Before cooking the project, go to Edit / Project Settings / Maps & Modes / Game Instance and set Game Instance Class to LiveLinkGameInstance.
  • Close the Unreal Editor before loading the project in Aximmetry because the MVN Live Link can only handle a single active connection.

NVIDIA DLSS

Follow the official installation guide that's included with the downloaded plugin (DLSS_Plugin_Installation_Guide.pdf).

  • Ensure your system meets the prerequisites listed in the official installation guide. It is very important to install the required graphics driver.
  • In step 5, copy the plugin to Epic Games\UE_4.26\Engine\Plugins\Marketplace instead of Epic Games\UE_4.26\Engine\Plugins\Runtime\Nvidia.
  • In step 6, launch Unreal Editor for Aximmetry and install the plugins as described above.

iTween

  • Download the plugin from the link found here. Make sure to download the version that was compiled for the engine version that you are using (e.g. "compiled for 4.25" if you have UE 4.25 installed).
  • Extract the downloaded archive to Epic Games\UE_4.xx\Engine\Plugins\Marketplace\iTween.
  • Launch Unreal Editor for Aximmetry and install the plugins as described above.

Rokoko Studio Live

  • Open Plugins/Smartsuit/Source/Smartsuit/Public/SmartsuitBlueprintLibrary.h in a text editor and add Category = "Smartsuit" to the last two UFUNCTION lines. It should look like:

UFUNCTION(BlueprintPure, Category = "Smartsuit")
static FVector GetPropLocation(FProp InProp);

UFUNCTION(BlueprintPure, Category = "Smartsuit")
static FRotator GetPropRotation(FProp InProp);

  • Download the Eigen library from: here.
  • Copy all files except the src folder from the extracted eigen-3.3.7\Eigen folder to c:\Program Files\Epic Games\UE_4.xx\Engine\Source\ThirdParty\Eigen\Eigen.
  • Launch Unreal Editor for Aximmetry and install the plugins as described above.
Using the plugin in Cooked mode

Streaming animations into the Unreal Editor (in Live Sync mode) should work without problems after installing the plugin. Using the plugin in Cooked mode however, requires an additional step:

Open the Level blueprint in the Unreal Editor then add a Create Virtual Production Source node and connect it to the BeginPlay event. (If the node doesn't show up in the search results, try disabling the Context Sensitive option above the search box.)

After cooking the project, you should be able to stream animations into Aximmetry.

Make sure the Unreal Editor is not connected to Rokoko Studio when the project is loaded in Aximmetry (Rokoko Studio can't connect to multiple clients simultaneously). The safest option is to close the Unreal Editor after cooking the project.

Kawaii Physics

  • Download the plugin and copy the KawaiiPhysics folder to c:\Program Files\Epic Games\UE_4.xx\Engine\Plugins\Marketplace.
  • Launch Unreal Editor for Aximmetry and install the plugins as described above.
