Hey Prismaticrew! In today's episode of 5-Minute Materials we're looking at The Lerp Node, otherwise now as Linear Interpolate! This node allows us to interpolate (or blend) between two values, colours, textures, positions, and more! The Lerp Node is incredibly powerful and will be your best friend when it comes to creating awe-inspiring materials in Unreal Engine. If you're a beginner, you've come to the right place.as I'll show you several examples of what Lerp can be used for as well as some handy tips and explanations to help wrap your head around this wonderful function.

I'm always sure to like your videos before I even watch them, cause I know it's gonna be good. Keep it up dude, I love your teachings :)

5-Minute Materials. What a nice idea. Thanx again, Charlie!

@PrismaticaDev 3 года назад

Hope they're coming in handy! :)

@Xaeveax 3 года назад

I've found the lerp node is one of most useful and versatile nodes. It's got so many applications that people tend to overlook.

@PrismaticaDev 3 года назад

Absolutely - it's one of the most simple AND most complicated nodes on the block!

I love these vids so much. They're so useful! Would you consider making a video explaining the shortcuts in the material graph?

@PrismaticaDev 3 года назад

That's an amazing idea! I'll have to brush up on all of them haha especially since when I go to type something in, they're all out of order with the latest patch haha

@CosmicComputer 3 года назад

Excellent as always! Thanks! Would you ever consider “5-minute” blueprint nodes/behavior tree tasks etc reviews? I really enjoy your content and this format. Either way, love your channel man!

@PrismaticaDev 3 года назад

Heya Logan! If you're looking short Blueprint videos I HIGHLY recommend Mathew Wadstein's channel. He's already covered every single BP node in short videos and that's what inspired me to create this series :) I think he also covers Behaviour tree things

Who is cheaper between lerp and BlendMaterialAttribute？

@PrismaticaDev Год назад

BlendMaterialAttribute is like a Lerp but for every single material attribute at once. So it "might" be cheaper to use it if you're blending entire materials together (if they do some funky stuff under the hood) but otherwise a Lerp will be cheaper.

@christuusgnosis Год назад

I wish I had found this a year ago its one of the strangest things in unreal to figure out because its everywhere and there is no real instruction from unreal about how it works good tut

@user-ot4ww5by3r 4 месяца назад

does it work for interpolating texture in three.js?

@PrismaticaDev 4 месяца назад

Hey hey - not sure what you mean. What is three.js?

@Jake-co7rt 2 года назад

My Materials Lerps don't seem to work... AT ALL. Always looks like the alpha is at 0, no matter what I use for input, or even if I just change the number without plugging anything in. Might there be a setting I'm overlooking?

@PrismaticaDev 2 года назад

Hey Jake! Sounds very odd indeed... You might be using a Material Instance of the material which has its alpha setting at 0? And the Master materials changes might not propagate. That would only be the case if you were using parameters though... Would you mind sending me a screenshot on Discord?

@Jake-co7rt 2 года назад

@@PrismaticaDev, Thanks Very Much. For anyone who might have a similar issue: Make sure your color parameters have DIFFERENT names, or Lerp treats them as just ONE parameter even though they appear to be different. Charlie spotted it immediately, and it fixed the problem completely. Bravo, Dude. (c:

@PhantomZtryker 3 года назад

What's the difference between saturate and clamp?

@PrismaticaDev 3 года назад

A clamp allows you to choose what values you want the clamp to be (presumably by using Min and Max functions) so you'd be able to clamp negative 1 to positive 2, for example. Saturate, on the other hand, always clamps 0 to 1 but it completely free on most GPUs according to the tooltip :)

@PhantomZtryker 3 года назад

@@PrismaticaDev Good to know, thank you.

@vincenzoarnone7406 3 года назад

The "saturate node" tip to clamp a value it's really cool, but accordng to the 'Performance Guidelines for Artists and Designers' the Clamp node has a different performance cost when using 0 and 1 values, so I think it is using a similar (if not the same) algorithm in the background with those values. docs.unrealengine.com/en-US/TestingAndOptimization/PerformanceAndProfiling/Guidelines/index.html

@PrismaticaDev 3 года назад

@@vincenzoarnone7406 Good pickup! I imagined Clamp 0-1 would get optimized to do that. The saturate node is nice and small though :P
