Unreal Fluid Dynamics

Some basic commands I gathered from the several tutorials

Settings Editor,  to get to the console

Basics editor

• Navigate in editor by using left mouse (horizontal), right mouse (rotation) and both (vertical) .  Mouse-wheel (distance horizontal).  With this method, use high camera speed
• Alt and mouse  for staying looking at object.
• Ctrl + right mouse : move object y-axis (green)
• Ctrl + left mouse : move object x -axis (red)
• Ctrl + both mouse : move object z axis (blue)
• Ctrl + Shift ……  Camera will follow the object
• Space bar : rotation mode, scale mode….
• copying:  Ctrl C / V, Ctrl + W,  Alt
• Select blue axis and end, object falls on the ground
• Edit mode: Ctrl to select a point. Alt to extrude face
• Alt to duplicate
• H to hide objects, Ctrl H to make all hidden object visible again
• G shows how the scene looks in game mode
• F zoom to selected object
• V to vertex Snap
• Alt + MMB temporarily offset the pivot
• F11 full screen
• F2 Rename object
• CTRL + B Find asset in content browser
• CTRL + P Open an asset
• END drop mesh to the floor
• L + Click to add a light
• CTRL + 0..9 = set bookmark to viewport
• 0..9 = Jump back to bookmark
• CTRL ZOOM zooms in further

Building

• First select material then load geometry
• With BSP textures, select all faces and choose align in the proprieties box.
• Mesh, duplicate mesh, place on the proper location and replace by proper mesh.
• Size of objects 5 10 …same as the grid
• Ctrl G to make a group
• Ctrl Shift G is temporary ungroup to take out one part. Finish with Ctrl Shift G again.

Blueprints

• CTRL + [0-9]. Save  current location and zoom level in the Blueprint Editor.
• SHIFT + [0-9]  Return to that graph at that location and zoom level
• m and left mouse   :  multiple node
• v and left mouse    : vectorparameter
• 1 and left mouse    : constant
• T and left mouse : Texture
• L and left mouse : Lerp
• M and left mouse : Multiply
• S and left mouse : scaleparameter
• U and left mouse: TexCoord
• Connection: Double click on line for reroute node
• Connection: alt and left mouse to disconnect
• Connection: Ctrl and left mouse to change connection
• When pulling variable in with Alt = set node with Ctrl get node
• Drag Node over existing Node to replace the Node
• F7 compile
• F2 rename
• CTRL + SHIFT + F Search in All blueprints
• Ctrl Move BP Connections

Landscape

• Ctrl 1 bookmarks camera position, with 1 you will go to this position
• Left Mouse Button to raise the Landscape height and Shift + Left Mouse Button will lower the height of the Landscape
• With landscape : change lod in details to increase performance.
• Afterwards you can add landscape

Console

• quit

Debugging

• GPU Visualiser : Ctrl Shift ,
• Debugging when running in Visual Studio

Materials

• Left mouse click +
• A Add
• B BumpOffset
• C Comment
• D Divide
• E Power
• F MaterialFunctionCall
• I If
• L LinearInterpolate
• M Multiply
• N Normalize
• O OneMinus
• P Panner
• R ReflectionVector
• S ScalarParameter
• T TextureSample
• U TexCoord
• V VectorParameter
• 1 Constant
• 2 Constant2Vector
• 3 Constant3Vector
• 4 Constant4Vector
• Shift + C ComponentMask
• PlotFunctionOnGraph node
• DebugScalarValues
• WorldAlignedTexture

Notes from the video concerning debugging

• 32 min : BP visualizer. Works only when game is running in editor. Right click on variable to make value’s visual.
• Window > Developer tools > Blueprint Debugger > watch
  Show values of all selected variables.
  Faster solution Window > debug
• 33.14 min; Visual logging. Enable in PB
  Window > Developer tools > Visual logger.

• Ticking : add Nodes : Vislogtext, VislogBoxshape, Visloglocation, VislogSegment
• Stat commands : Stat Game
• While playing hit TAB. Stat Game of Dumpticks
• 36.23 min Profiler Tool
• Reference viewer. Right click on BP > Ref viewer
• Size map. Right click on BP > Sizemap
• Use child BP . Video
• 47.48 min. In a function, never reference directly to content (material for example), because all referenced contact will be loaded with the BP. Reference with a variable.
• 49.27 min, page 122: Dynamic asset loading use Async Load Asset.
• Use maps : variable – mesh, page 123

• Tips from the video

I am following the beginners at udemy https://www.udemy.com/unreal-engine-4-the-complete-beginners-course/learn/v4/content

In this post notes from me:

• Open asset to view separate assets
• material is also an asset

Notes:

VR instance stereo
Run the game in standalone (right click .uproject file and select launch), switch to VR with alt+enter. Then do “profilegpu”.

Iets oudere video (dec 2016)

Notes:

• Right mouse click is selecting
• Scene, units, centimeters
• Clip, end, 500 m
• edit mode, 7 (topview), A (select All), U, Smart UV project, ok
• Make UV for ligthing,  Data (upper left), UVMap.Light, select this map, topview, Lightmap Pack
• Export FBX settings, according to video
•  
• Forward in Blender is negative y, in UE pos x. So
• Left click confirm, Right click cancel
• Never change the scale
• Don’t rotate
