Unreal Engine 5 - First steps with "Lumen"

General / 27 May 2021

my lumen attempt.
a guitar from the inside. made this scene some years ago and never finished it. only a directional light was used here. didn't get the warm up to work so exposure comes late #ue5 #lumen #unrealengine

Doubled geometry fix with Unreal Engine Ray Tracing and World Position Offset (weird shadow bug)

General / 08 February 2021

Not really something new and you can find the fix elsewhere on the internet too,

but since i tend to forget this handy little property, i'll archive this here too:

problem: when using ray tracing and also having WPO in use e.g. in your vegetation shader, your polygons will be displayed twice.

to fix this, click on your actor, open the advanced rollout for rendering and turn on:

- evaluate world position offset

this will remove the static rendered geometry from your object and also remove the weird shadows that come with it.

however there is currently (UE v4.26.1) no fix for this when using instanced meshes. so you can only disable any WPO effects from your grasses when you placed these as instanced geometry from the foliage tool.

i will update this post once i found a solution


Virtual landscape texture blends with objects

General / 05 February 2021

currently i prepare some small tutorial on how to blend a virtual landscape texture onto objects. and i got a bit carried away..

result is this .... thingy
no one knows why and what it does. but it put the starter content PFX to good use :D


Creating a basic mission marker in Unreal Engine 4

General / 29 January 2021

Learn how to create a simple mission marker in Unreal Engine 4 Features of it are: 

  • renders above all other objects 
  • stays the same screensize regardless how far the player is away

Place object XX cm infront of hit location

General / 15 December 2020

you see the blueprint of a projectile  that is some kind of portal and places itself in front of the hitlocation.

the "get dan character" is nothing else than the player character. So that the object also rotated itself towards the player


Wiring up Anisotropy in an Unreal Engine Shader

General / 11 December 2020

This is obviously for the case you do not want to map your object. so a triplanar mapping.
Ofc this is also possible with normal UV's 


you can find an anisotropy map here:

Recalculate polygon normals in the shader in Unreal Engine

General / 06 December 2020

if you ever find yourself in a situation where you need to recalculate normals after displacing your mesh within the vertex shader. e.g. in conjunction with tesselation, there is a way to do this with the "normal from height" node


(I deactivated shadows on this object to show the effect more clearly)

it can be solved like this
note that you turn off tangent space normals in the main shader properties.


However the normals are then facetted

in order to get smoothed normals, you can use the "NormalFromHeight" node

the lower the normal offset, the higher you need to set the normal intensity.


  

Build Reflections with a Scene Capture Cube in Unreal Engine

General / 05 December 2020


in order to get sharp reflections on glass materials, you can use a scene capture cube.

just place a scene capture cube into the scene


create a render target image

and then setup this material


The texture sample holds the render target texture of course.

Monolithic Structure

General / 01 December 2020

For a school project i am currently working on a gigantic structure with my class. This post is constantly updated. whilst the lowest posts are the earlies WIP images and videos




this is the concept picture
