Select SM > RMB > Select > Select Matching (All Classes)

Select Actor/s > ALT + MMB + Drag

Simulate scene.

With selected actors, press K to save their transform state.

UE units are in centimeters.

Following any move or rename, RMB the directory to access and process Fix Up Redirectors in Folder. This will update and links between the moved or renamed asset to any other asset/s that is referenced or it itself references.

To view redirectors in a directory with the Content Browser, navigate to Filter > Other > Show Redirectors.

Utilize the following sandbox directory for prototyping, experimenting, and collaborative development efforts.

Content Browser > View Options > Show Developers Content

Import Marketplace content into a temporary project and then Migrate into actual project to help manage organization of different sourced content and mitigate extraneous content.

Generate a base environment lighting setup with Window > Environment Light Mixer.

When set to greater than 1, this is shown as a gradient in the swatch and is used to denote the intensity of the 'glow'.

Tracks can be added to multiple actors by selecting them all and adding the relevant tracks, which will add to each of the selected actors at the same time. This can save time and coordination over individually managing actor tracks.

Views can be set to bookmarks for quick navigation amongst cameras.

The following parameters can contribute to the application of motion blur:

Experimentation discovered that the following setting removed trailing motion blur artifacts in cinematic renders:

Setup

Add New Comp

Window > Virtual Production > Composure Compositing

RMB (in Composure Compositing) > Create New Comp > Empty Comp Shot

RMB (new comp) > Add Layer Element > Media Plate

Navigate to Details > Composure > Inputs > Media Source.

Frustum culling is enabled by default, but distance culling and precomputed visibility need to be manually enabled.

With transparency, manage performance with Viewport, View Mode > Optimization Viewmodes > Shader Complexity.

When constructing shaders, manage the number of instructions required for it. Higher number of instructions impacts real-time performance.

Note that UE uses pixel shaders, so the number of pixels in the viewport will impact the performance.

In a simplified way, draw calls are the number of objects in the scene, each of which are rendered separately; then each material within the object is also a separate draw call. Draw calls are more than this simplified way of thinking about it, but it is not entirely dependent on poly count; instead focus on number of different objects and their materials.

Reference the following command to monitor Triangles drawn and Draw Primitive Calls:

Dynamic shadows are very performance intensive, not necessarily the lights in the scene. Note that dynamic shadows are highly reliant on the polygon count in the scene. Instead, consider static lighting for shadows.

When importing the FBX, enable FBX Import Options > Mesh > Skeletal Mesh.

This enables the Import Morph Targets option, which should also be enabled to access the morph targets in the incoming FBX file.

This is a powerful asset management tool and integrator among a variety of tools, including Unreal Engine, Unity, Houdini, and many others. The assets are sourced from Quixel's Megascan library, which continuously grow in size and diversity. Their high quality make them ideal for quick use in just about any type of environment development. They even include the applicable LODs necessary to provide optimization within the created environment, and can be further refined with custom LOD Settings in UE. I've used this in a few instances to mostly test Blueprints in UE, but the process for accessing and integrating them is very quick and simple.

Advantages

Utilize Nanite where possible and applicable

Recommended Applicability

Unsupported

Efficient compression integration.

Potential Challenges

Initialize new actions via Bindings:

Once initialized, these action mappings will be accessible via BPs as Input Actions that reference the Action Mapping name specified under Project Settings.

This is a short video of actual gameplay within Unreal Engine 4 that documents the initial setup of a character that I conceptualized, modeled, rigged, and textured recently. I had a lot of fun developing it that I wanted to see it in action, so this is the first work-in-progress as I integrate the character and its assets into Unreal Engine 4. It includes cloth simulation and socket assignments to manage the bow and knife assets. Stay tuned; more WIP videos will follow.

This is to allow for the app to be quickly deployed for testing on the mobile device (iPad,iPhone) which has the enabled UE app. It primarily focuses on the UI elements of the app.

Settings > Plugins > Remote Session (enabled)

Unreal Remote 2 (URemote) Connect to IP Address and await Play on UE4 session

Play > New Editor Window (PIE)

Note

Does not permit AR functionality, even with the correct AR plugin configured in Plugins, since the AR Session will not be enabled via the Play, but only with a full deploy through XCode and mobile device (iOS).

Log Note

(Message received during testing) Attempting to start an AR session but there is no AR plugin configured. To use AR, enable the proper AR plugin in the Plugin Settings.

Session Type:

Test with 'Image' Session Type does not appear to make impact

Verify all tracked images are included here.

Window > Details to access additional info for that specific data asset.

Note: These controls are visible and function with the Remote Session

Setup: Session Type: Image Reset Camera Tracking: Disabled Reset Tracked Objects: Disabled (Not applicable to tracked images) Candidate Images: 1 data asset assigned

Result: Object spawned upon image detection but then the object stuck to the camera and the camera's movement. It did not track with the image.

BP_Pawn Transformation of spawned object: Y-axis transformation to towards and away from the camera. +Y means the object gets spawned closer to the camera and vice versa.

Setup: Image Session Type, spawn in level BP, transform attempt in pawn BP Print Log: Get All AR Tracked Images: ARTrackedImage_2147482043 Get Local to World Transform: Actual XYZ coordinates BP_Placeable: false
