Connect a Timer to a Create Event node to enable a greater deal of flexibility. This allows the Timer interval to trigger a Function or Custom Event from the Blueprint itself or another object altogether. In addition, this allows the creation of Timers within Functions themselves.

Unreal Engine
Tips & Tricks


073.

Timers

Blueprints | Events | Functions

Utilize Timers to execute a function or custom event after a given interval, which can be looped. These are useful for functionality such as; stat regen, cooldowns, attack intervals, damage over time, and much more.

Utilize the Rotate About Axis nodes to rotate Static Meshes purely by the material. This offloads rotation computation from the CPU over to the GPU. Do note that this does not move the physical location of the Static Mesh.


066.

The Vertex Interpolator Node

Materials | Optimization

Similar to the Customized UV feature, the Vertex Interpolator Node offloads instructions from the Pixel Shader over to the Vertex Shader. But unlike its counterpart, it's more flexible as it's a readily available node.


065.

Customized UV's

Materials | Optimization

Optimize the performance of your materials by utilizing the Customized UV's feature. This offloads texture UV calculations from the Pixel Shader over to the Vertex Shader. And as an added bonus, it helps clean up your graph.
