UE4 Tutorials by tharlevfx


#1

Not really VFX but I had someone email me and ask me about how to do this sort of tiling techniques in Unreal this week so I thought I’d make a little video and help them out:


Breaking Up Tiling Materials in UE4

any feedback or comments or questions for future videos would be welcome!

Object Space Gradients in UE4

another little material math tutorial - this time how to create a procedural gradient in object space!


#3

I love these kinds of tips and tricks! Super useful techniques to help build out a basic toolset.


#4

Using a rotator is far more expensive than appending coords in different orders. Since everything is at right angles, you can easily get away with a lot of -1 scaling and y,x appends. I wonder exactly how much more speedier it is…but i have it on good authority it would be important. :slight_smile:


#5

oh nice - yeah good thinking!


#6

I think you’ll dig this page. Note that there are different tabs at the top there.
I once made a randomized dungeon tile set in 3d. So fun.

Very cool - I love some tileset procedural generation!


Refraction and Distortion with Scene Colour in UE4

Another video talking about Refraction and creating our own distortion shader using Scene Colour and Screen Position.


#8

this is a very usefull and reliable technique!
Always good to understand the shader math of during mask creation.

I think Unreal 4.18+ now has a function for this called: BoundingBoxBased_0-1_UVW simplifies the network a bit.


#9

aha! i thought there must be a function for this but i couldn’t find anything when i searched. Always helps to know the right names for things :slight_smile:


#10

Yeah I made it into a function, until i accidentally pressed W in searching for a node and found it :smiley:


#11

Answered another question from a viewer this week about how to scale a SphereMask to make an oval shape:


Non Uniform Scaled Spheremask in UE4

#12

Creating a Looping Flipbook in After Effects

Something a little different this week - creating a looping flipbook from a simulation in After Effects. I know there’s cache blending techniques that work for this sort of thing as well but always good to know the basics too!
