Unreal Engine:
Short Cut:
for drag range of selection in the screen: Hold Alt+ Ctrl+ L mouse drag
Add keyframe for selected objects in Sequencer: S
F2 → Rename file
Duplicate: Ctrl+W or Hold Alt, Drag selected object
For Type script command in Otuput Log: Window > Developer Tool > Output Log
Blue Print Terminology:
Constant means number
Import any meshs/assets 3d objects from one UE project to another:
R click on the Mesh in the project → Asset Action → Migrate → Ok →
place in target UE project’s Content folder → Select Folder
To copy the animation of the Mesh: R click on Animation folder in Content Broswer → Ok →
Same folder as the Mesh → Yes All (overwrite)
Optimizing the environment in UE:
Check what meshes/element in the scene with complex points: Lit → Optimization Viewmode: Quad Overdraw
1.Use higher number of LOD on Meshes (to reduce numbers of triangle):
Double click on the Mesh, LOD setting → LOD group: small prop
2.Use LODs on Particle System (4:03 to 6:00)
3.Use right size textures (numbers of Mips, make sure the power of 2)
4.Don’t use oversize texture (mostly 4k is enough) : Lit → Optimization Viewmode: Required Texture Resolution, then click on Texture (scene selection) button to choose the part of the meshes (green color means texture is 2x over)
5.Optimize light (esp for small lights, e.g. spot light, point light and rectangle light), set to static and bake later save much more memory. If have to use dynamic, reduce the attenuation radius (test in Lit → Light Complexity (green color usually mean over lit)
Extra: Turn off unnecessary cast shadow of the lights in scene
