nDo Photoshop script v0.6.66 from Quixel to create normal maps in Photoshop

General / 08 April 2022

I got the kind permission of Teddy from Quixel to share their old nDo script for Photoshop to create normal maps from color maps or from b/w masks. 

The script seems to be eradicated from the internet for years, so perhaps it helps someone if it can be found here again.
Unfortunately I only have the version 0.6.66.

Since Adobe seems to phase out their 3D support and with it seemingly also their internal normalmap maker tool, and also since the Quixel suite is likely to be abandoned, the old nDo script comes in handy again when we want to create quick normalmaps right inside of photoshop, without having to mess with other software or online apps.

Download the script here

Then place the nDo folder right into the root of C:

Then open Photoshop and drag'n'drop the file

nDo.atn

right into the actions window of PS.

When there is no Actions Tab, just open the Window menu and activate it.

Then just select the nDo script and press play, whilst having some kind of texture file open.

Then play around with all of its settings.
In order to create very deep normalmaps, you have to work with several layers that can be overlayed over another, each having a slightly higher radius.

For that author your first micro detail normal, then press duplicate, set it to overlay and adjust a higher radius and perhaps lower the depth a bit, then repeat the process until you are satisfied. Of course it helps to also take the other slider options into account, but that heavily depends on the source texture material.

Don't forget to flatten your normal and flip its green channel when exporting for Unreal (DX normal format)

Big THX to Teddy and all people who worked on this game changer back in the day!

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

[EDIT]
So yea there is a weird workaround. will shared it in one of his videos here:



basically ou would make a blueprint turn that tick on, make an actor foliage actor and then paint the thing


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

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.
