Been having some trouble trying to learn Unreal lately, but then I came into your videos and now I don't feel so lost 😊 Great content! 🙏 congrats for your work
If you mesh is all white instead of showing the vertex colors try this out: When importing the mesh into Unreal you will find a "Vertex Color Import Option" it is under the Advanced taps of the Mesh options. There select "Replace" instead of "Ignore".
@@PrismaticaDev Awesome! Yeah I actually looked into it a bit, that's so cool. Definitely going to play around with that and try to find one I like. Thanks!
Though one thing eludes me is, saturate node is 0-1, but how does it work with - 1 , so in ur vid, vertex colour red minus 0.5 and then x 2 and x - 2, then add saturate node, so end result would of been - 1 and 1 but when u use saturate I'm just lost on how it works with negative values
Welp I’ve got what I needed 4:21 I’ll drop a like for making it quick 😂 I can’t even count the tutorials that describe what they’re about to do, as if there wasn’t a title
Can you make it like each 0.1 number from 0 to 1 on a channel is a seperate texture or effect? If so you could have a lot of options available per channel.
Kind of - if the vertex edges are hard, then you could do masking like that, although if you needed a gradient the effect would fall apart since going from 0 -> 1 would go through all of the layers. For that kind of effect I'd recommend using UV's instead, which I have a video about (search "reduce draw calls")
Thoughts on using RVT on a plane instead of decals to remove draw call issue and get some cool additional material features ? See Runtime Virtual Texture vs Decals videos on YT
What is the float precision of vertex colors in the material editor? I notice that after the second decimal place they change from the colors on the original mesh. This leads me to think that they are only half-precision. Could it be? My goal is to read vertex colors in the Material Editor with at least 6 decimal places fidelity (single precision) to the vertex colors on the original fbx.
Yeah I'm pretty sure they're half floats. If you need full precision, UV channels are your friend. However, that only works if you don't need per-mesh painting
@@PrismaticaDev Thanks! Using UVs is what I'm exploring right now. Regarding Vertex Colors, as I understand they are stored as 8-bit integers and converted to float for editor use, thus losing precision during the float-int-float route... Cheers!
I love how you tried to get your cat to sit and stay and then it just politely told you to Eff off :P Clearly you've had a dog before and expected the same result :P
Hey Charles - really been enjoying your videos which I've been binging on - May I ask would you make your leaves grow (deform scale) using the vertex colour data at varying speeds on a per instance level?? Asking for a friend x
I wanted to understand why use height map in the B channel for the alphas of the lerp. Also why use only one height map and not two since there are two texture, can it be any height map, which height map should I choose between the two textures you're lerping?
Hello! The reason my height channel come from B is because I pack my Normals in to the RG, and then use the B and A for greyscale colour masks/height data. My game project doesn't use colour textures or roughness/specular/metallic maps so I decided to pack everything in to 1 texture to save a bunch of performance and memory. As for using 2 height maps, you totally can! There's a function called "HeightLerp with 2 heightmaps" or something that can do that. I think it works by just adding them together and dividing them by 2 (the average of the heightmaps)
@@PrismaticaDev Thank you for the swift reply. I'm kinda new to this and have no idea how to get heightmaps. Currently using Quixel Mixer at the moment. So far I don't see any height maps on the export options only displacement. Is there a way to get heightmaps from quixel mixer or bridge? Is there anywhere I can generate heightmaps without drawing them myself or maybe pack multiple maps in different channels like you did. Thank you again for the help.
Hey there - I’m not 100% sure I understand. Do you want to use vertex colour as lighting data, eg. Nintendo 64 games. If so, you can use some of the included material functions like ‘blend overlay’ and plug the vertex RGB into there
@@PrismaticaDev Hello, thank you for getting back to me. 😀 Yes, but without being affected by the colour parameters. Using blend_overlay alters the colours of the vertex shading. In my case, I have an item that sines between dark orange and light orange, and I want to overlay the blue vertex lighting data on top of the item without turning it brown. I have tried using the verted colours as a mask, to no avail. Hopefully that makes a little more sense.
@@Iobsterpeterson Ah I think I get you. It sounds like you'll want to use a Lerp, however I'm not sure what would look best to use as the Alpha. Maybe the Length of the R G and B, then saturated/clamped?
is it possible to have multiple paintable (in unreal) vertex color sets? i know in the Last Of Us Part 1 remake they have 2 vertex color sets and i was just wondering if that's something we can replicate in unreal.
I'm not exactly sure - I'm sure it's possible but you wouldn't be able to access them both at the same time. Definitely something I'm interested in though!
Not yet, but I know they're working on it. You can still use "default" vertex colour (aka pre-painted in Blender) but you can't change it per-mesh in the editor. Now sure what's taking them so long haha
Good day sir. How did you save your file (material editor) in a couple of seconds ( 15:38 )? It took me 8-10 seconds to save my material editor just by checking "2 side material" and save. Thank you my unit is RTX 3050, 32g ram, AMD Ryzen 7 5800.
It's just because it's a very small shader - my character shader takes years to save sometimes haha. My specs are similar to yours, so it just varies shader by shader Now that I think about it, are you using Static Lighting? If you disable it in your Project settings, you won't need to compile shaders for that lighting mode (makes it 33% - 50% faster,) also if you aren't using the shader on Skeletal or Cloth meshes, changing the "used by" tickboxes can save some time
@@PrismaticaDev Thank you so much! By the way, I have just noticed why some of my objects turn black in real-time ( I'm using a lumen). But when I turn on my path tracing, it goes back to normal.
Hey Charles, would you have any tips on how to use vertex colors as a material mask using a layered material? For example I would model a car seat and break up the mesh with seams and assign different vert colors to the different parts, would I be able to mask out each of those parts using the assigned colors? How would I go about doing that? Edit : I essentially would want to 'flood' each part of the mesh with a solid color and use that solid color as a mask in UE.
So how does vertex color work with nanite? If I have millions of tris on a model can I get pretty detailed vertex color as well? Anyone tested this? Because I really enjoy painting in zbrush just for the feel of it, it’d be nice if that transfers well with nanite.
@@MaestroRNGs right, i was just wondering if you could get highly detailed vertex paint since nanite allows for very polygon dense meshes so therefore higher vert pain resolutions

Awesome. The last tip about splitting the same channel is great.
Yay! New vid!
Glad you are doing more videos again
Nice tutorial and great talking style!
Another amazing video. By the way, what is the background you have inside your blueprint editor window? That's awesome!
It’s just an editor setting - it’s a material! :)
