Creating streamlines from Unstructured_grid

[danteandlion]

Hello, I've followed the node trees as shown on the BVTKnodes website, but the node tree isn't available either. Blender generates an output, there is no error,but I cannot see the streamlines.Attached are images of my node tree setups.

Thank you

Hi, the stream tracer node example tree should be available in Tree tab --> Examples --> cubeflown_stream_tracers. Is it not available for you? Are you using latest version of add-on? If you go to Inspect tab, does it show version numbers?

Hi,thank you for your reply. My add-on version is 0.8. If I use the example tree, it works normally, but if I replace my import file , I can't see the streamlines.

Hello, looks like your data has only point data. I'm guessing vtkStreamTracer requires cell data?

OK, thank you very much. I'll try again.
