Thanks to the both of you! I will use empty arrays then.

Yeah I’ve found that one (Koderz’s) yesterday and planned on looking into it today, as the PMC only supports one UV channel currently (maybe I could extend that myself easily? not sure yet).
Your examples look interesting and I’d like to check them out, but I have to ask you to help this noob out once more please:
What do I have to do to get that ProceduralMeshDemos.uproject running in 4.15?
When I unzip it (GitHub - SiggiG/ProceduralMeshDemos: Examples of procedural mesh generation in Unreal 4.), I double click ProceduralMeshDemos.uproject and a “Select Unreal Engine Version” dialog pops up. The only option is 4.15 (because I only have that one installed I guess), I press OK and then I get this error:

I only have Visual Studio 2015 installed on my machine. Does that make a difference? It’s probably rather an issue with my UE version, right?
When I press OK and double click that project again, I get a dialog pop up that says “UE4Editor-ProceduralMeshDemos.dll” is missing. “Would you like to rebuild them now?” -> Yes. -> Error: ProceduralMeshDemos could not be compiled. Try rebuilding from source manually.

What can I do? Thanks!

I recently updated the sample to work in UE 4.16 which has a few changes to the build system. I created a branch with the 4.15 version you can use, but not updating that one anymore.
