I love these kinds of tips and tricks! Super useful techniques to help build out a basic toolset.
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. 
oh nice - yeah good thinking!

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!

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.
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
Yeah I made it into a function, until i accidentally pressed W in searching for a node and found it 
Answered another question from a viewer this week about how to scale a SphereMask to make an oval shape:

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!
