Hey hey! Today we're talking about Custom Data, or Custom Primitive Data which is an extremely awesome way to create variation in your assets, as well as a very effective way of optimizing your scene. Draw calls can be a huge performance bottleneck if left unchecked, but Custom Data allows us to have control over colours and other parameters in materials without breaking instancing or creating many material instances.
Enjoy!

For those of you who are adding isntances to Instanced Static Mesh Component you need to use PerInstance Custom Primitive Data node in the material. That will then set the material values on specified instance instead of the parent instanced static mesh component.

Yessir! IF anyone is interested you can check out my "individual foliage logic" video for some examples ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-6sjc4dqoCF0.html&ab_channel=PrismaticaDev

@lennybunny93 2 месяца назад

A little PSA to everyone having the same issue. If in UE5.1and later if your custom primitive data doesn't show during runtime while using a Blueprint, it's because you need to setup a default custom primitive data value in Blueprint, after you set the default you can change the value using the set custom primitive data

@t3hpwninat0r 2 года назад

I can see the value of adding a component to an actor that gives me buttons in the editor for randomising custom data floats or using the colour picker to set values at a particular index, or even setting values based on some other thing like world z position, copy scale value into custom data float, and of course the most obvious one is to let the actor's blueprint change the value at runtime for whatever reason, like maybe to control how high the red part should be on an old mercury thermometer

@PrismaticaDev 2 года назад

Yesss absolutely - I've been thinking of making a tool that allows the use of an actual colour picker etc instead of the 3 floats haha

@Fokkusu 2 года назад

yoo this shit is lit 🔥🔥 fam 👌😆 💯. Now in a more serious note, if material instances help a lot by being well, instances with allow for variants for the same mat, this is like the same improvement from using different materials for each variant with instances but this custom data improves on the instances, this is WILD. I'm 1000000000000% going to use this. Thanks a lot for this tutorial! :D, this is going to be PERFECT for our object instance system, we will be able to basically instance ALMOST EVERYTHING now

@captaindeabo8206 2 года назад

This is brilliant thanks. i asked myself somtimes what s meant whit the term in UE. Now i Know it Thanks . But i have one point of critique: The Index of a list or arrays are always Integers not a floats. 1 and not 1.0. Its used to numerated or count entry`s in an data structure this is done whit natural numbers. Its like the numeration of the drawers of a shelf. there is usally no onehalf drawer. In this case serval Material paramters (or data in form of a float) are stored in on drawer or(list entry) and numerated via the assignmend of an index (integer).

@PrismaticaDev 2 года назад

You're correct - although when I say "custom data floats" I mean that the values assigned to each index/ integer are floats, not the indices themselves haha

@3DWithLairdWT 2 года назад

Are the custom data values something you can manipulate in BPs during construction or during gameplay? I'd love to implement this into my Trim Sheet based Env project

@PrismaticaDev 2 года назад

they absolutely are :) If you have a reference to the static mesh just drag a pin off of it and look for "set custom primitive data" or something. It's a much better option than setting a material parameter because when you set a material parameter at runtime, it automatically converts that material to a Dynamic Material Instance (which will break instancing/batching for that object)

@Nefrann 2 года назад

Thank you so much for this! Can you use it with Foliage actors? I can't find the "Custom primitive data" option anywhere in foliage stuff :/

@PrismaticaDev 2 года назад

Hey hey there! Unfortunately it isn't exposed by default within the foliage tool, although it's definitely on the foliage instances since I use it to do instanced foliage interaction.

@unrealfreedom1807 9 месяцев назад

Hey this is an amazing tutorial thank you for all your work! How did you achieve these shadow details? There is a pattern in the shadows. How did you do this?

@PrismaticaDev 9 месяцев назад

It's just some basic cel-shading :) It turns gradients in to distinct bands which results in some nice textures

@dreamingacacia 2 года назад

I'm not sure if there is an update on this topic but I found this accidently. So I ticked the custom primitive data while the node selected then the name of the parameter including their variables appeared at the object, with this is simpler and nothing to confuse about. Therefore I don't need to be too careful when changing the variables. I'm not sure if this is because they updated it or I just happened to found a better way, but I think I should mention here.

@marcusunivers Год назад

My approach is to create Actor Blueprints with puplic variables for manipulating each Mat Inst. But for an easy and dirty way this is good ;)

@paradox8425 2 года назад

Does it reduces movable meshes draw call too? Or is it static only?

@plasid2 2 года назад

its something similar to apply the same LODs for multi static meshes? I freak out clicking every single static mesh and chenge number of LOD and camera distance value

@boraycobanoglu1372 11 месяцев назад

@PrismaticaDev 6 месяцев назад

Hmmm... I'm not actually sure! I'll need to test it out myself to confirm. Maybe if the actors are all set to be Static it will have an easier time dyna-instancing them. It could also be something to do with the separate pass for translucent stuff. I'll report back after some doodling!

is there a way to make a parameter with only 3 floats in to a custom data. I have base colours that don't have an alpha channel and if i convert those to custom data it adds a 4th channel. Great vid btw. I absolutely am currently making multiple material instances just for colour variation like you explained and this would be way more efficient.

@PrismaticaDev 2 года назад

I think the only way would be to make 3 single float values and then fed them in to a MakeFloat3 node.

@alhusseinali 4 месяца назад

Yo, I used to use "dynamic martial instance" to change the texture but it seems like it cause a drawcall per every mesh get applies, the solution is to use a new method called "Custom primitive data" but I wonder Can I use this method to change the texture maps or just the color?

@PrismaticaDev 4 месяца назад

Hey hey! You can, although it will increase the shader complexity slightly. You'll need to set up a Switch node with all of the textures being sampled (not a big deal if it's just 2 or 3) and then in to the Value input, you'll put a Custom Data value. So all 3 textures will be sampled, but then you use Custom Data to "show" which one you want, without needing to do dynamic materials.

@_batt Год назад

Here's a question for you, do you think it would be possible to use a scalar custom data as sort of an "index" to choose between a set of different textures in the same material? Like for example, I have a sign model but a bunch of different decals that go on the sign. The scalar is hooked up somewhere in the sign's single material, so if I put in "2" it chooses the second texture, if I put in "8" it chooses the 8th texture, etc. I have the idea in my mind but I'm not familiar with the math required to make it work.

@PrismaticaDev Год назад

Yep! Absolutely. You can use the Flipbook function for exactly that

@aeonkitsune3132 2 года назад

Do you think it would be possible to use custom data on an npc that gets skeletal mesh merged at event begin play? I'm poking around with it, and the way I currently have it, in the blueprint viewport my custom data adjustments are showing up, but after getting merged when I hit play to test the game it gets reset. My guess is the new merged mesh doesn't keep the custom data. Do you think there's any way to transfer the custom data into the skeletal merged mesh?

@PrismaticaDev 2 года назад

You should be able to use the “set custom primitive data” function in blueprint to change the custom data at runtime :)

Correct - Custom Data is limited to floats only, like UV data and Vertex Colour. However, you can sample multiple textures and then use Custom Data to Lerp between them, or use a Switch node :)

@SockeYoutube Год назад

Is there also such an optimization for decals? I wanted to make a game like Splatoon but each decal costs 1 drawcall and that is extreme. All decals have had the same material.

@PrismaticaDev Год назад

I'm not entirely sure, but I believe splatoon uses runtime vertex painting for their splats. Decals can be pretty expensive on the rendering side, let alone the draw calls, so it's always fun to think of alternate solutions. Maybe check out my videos about my Blood system for some inspiration!

Correcto - however using a Dynamic Instanced Material will prevent the mesh from being dynamically batched/instanced. Custom Primitive Data allows them to be batched together in to 1 draw call
