BuildVolumeMesh issue

Hi

I see what you are trying to achieve. Your solution will unfortunately not do it, for reasons I will explain in the next post. Give me some time and I will come up with something useful.

I haven't looked at the UV thing yet, will do it soon too.

I removed the project zip file you posted earlier, because it had a copy of Curvy Splines in it. This forum being public, that meant that anyone can get a free copy of Curvy Splines. Let me know if you need a copy of that zip, I still have it on my pc.

About the missing example scene, I just downloaded a copy of Curvy Splines from the store, and it did contain the example scene 29_CGDeformMesh_BarbedWire. This is the one you are speaking about right? If so, can you reimport Curvy's package and see if it is still missing?

Thanks for your patience

Of course you should remove Curvy Spline library. I was wanting the project to work when you opened it so included it. Silly of me as you 'likely' have it... ha ha

I was not talking about the BarbedWire example. I was talking about the railroad track example with a figure eight where you show the Metadata is used to change 'track sleepers' and ground cover and rails. It has the overhead wires etc.... Not sure you have another tutorial example that change textures with Metadata.

Now about why the solution your tried to implement is not working:

• The Deform Mesh module deform a mesh along a path, and not on top of a volume. The module can take volumes as inputs, but use only their path, not their surface. Now I see that this is source of confusion. I will try to improve this in the future.
  
• The Bounds input of the Volume Spots module, and the V Mesh input of the Deform Mesh module, should both be linked to the same V Mesh output. This is not the case in your generator. Basically, the Volume Spots generates spots based on the bounds of the mesh, and the Deform Mesh deforms the meshes based on their spots' positions.
  
• The GuardRail mesh needed to be rotated by 90 degrees (using the TRS Mesh module)
  
• I haven't investiguated much this last point, but the result seemed wrong when using the CPs range in the Track input spline path module. Using other ranges worked fine.
  

I can use Volume Spots to align object to the edge of the 'track' (like 'guard rail' support 'pole' objects) but I'd like an extruded 'guard rail' go with the 'poles' too.

I am not sure I understand how to reconfigure this from your textual description. Can you give me a 'generator' that show a how to connect up a graph that has a shape extrusion ('guard rail') aligned to the edge of another shape extrusion ('track')?
