Welcome

I want to build a Virtual World in Unreal Engine,  with the purpose of educating Fluid Dynamics.  Still a lot of work has to be done.

First video on the project

Update June 2018
Followed several online courses on using blueprints in Unreal Engine.
See https://unreal.fluiddynamics.eu/main-water-system-in-unreal/

First video will follow soon?

Update October 2017. After a long time following courses on how to build in Unreal Engine, I finally have started with building blueprints. Busy building a watersystem

Update may 2017. I have reactivated the project. Was too busy with ordinary work :-). I am following a course on Udemy (Unreal Engine 4: How to Develop Your First Two Games) to get my skills on a higher level.

M_FD_Surfacewater

Material for the surface water on the island

Uses Absolute World Position Node.

How to get the flow direction according to the direction of the channel?

General notes

  • With vertex color, you can control 4 values (red, green, blue, alpha)
  • red = speed x
  • green = speed y
  • blue =?
  • alpha =?
  • I don’t get this working yet

Water material

I looked into different tutorials. In this page step for step my water material.

Notes:

Result:

Tiling will be adjusted so that the “basic” block is 1 * 1 m. Each Branch in the FD_watersystem will have its own instance of the watermaterial. In BP I can set the parameters for each branch.

  • S Scalervector
  • Append x and y

Future optimisations

  • Small wave/ ripples by wind. So direction is based on wind.
  • Swimmable water?
  • Particles
  • vertex painting
In my case it is mirrored

Replication

To get a multiplayer working properly replication is important. Until now I have no knowledge on replication?

Aim is to use blueprints

In this post the notes (things I want to remember) when watching the tutorials.

Video chapter 1, basics

  • Navigate in editor by using left mouse, right mouse and both. With this methode, 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
  • Spacebar : rotation mode
  • 2 x Spacebar : scale mode
  • copying:  Ctrl C / V, Ctrl + W,  Alt

Video 2 building

  • 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
