Hi, I’m having an issue. I have a spline that dynamically creates instanced meshes along its path. Everything works perfectly in terms of creating the instances, but I want each instanced mesh to have a different color. I’m trying to achieve this in my material using a Per Instance Custom Data, but…

In the Details panel for the Instanced Static Mesh Component, under Instances, make sure you have set Num Custom Data Floats to the amount of custom data you’re using in the material. In this case set it to 1 [image] [EDIT] @ClockworkOcean is correct, you’re using the foliage version. Instead cr…

I did what you said, but it’s still the same. Am I missing something? [image] [image]

I think primitive data is another thing. Have you tried using a HISM instead of ISM?

Sorry, but what do you mean by HISM and ISM? I’m kind of a noob with these abbreviations.

Hierarchical instanced static mesh, just change the component type :slight_smile: [image] Everything else is the same.

Basically, what I want is to create a pipe that fades between two colors — in this case, red and blue. Maybe I’m overcomplicating things? This, with dynamic fade [Unreal Engine - Spline based Mesh Rendering, Auto Pipes ,Chains & Fence etc]

It works here ( ignore the material statement I made ) [image] I was also wrong about HISM, it does work with ISM too.

Yes, when I did it separately, everything worked. But what I actually need is something more like a video — I want to simulate a pipe where hot gas flows through and gradually cools down. That’s why I want it to start in red and fade into blue.
