I think tessellation will be discontinued in the future, but I will report it just in case.
The licensee is not keen on fixing this problem.
Check the NewMaterial of the attached project.
Or create a Material as shown in the attached image.
[SM5] /Engine/Generated/Material.ush(2492,2-41): warning X3206: implicit truncation of vector type
[SM5] /Plugin/FX/Niagara/Private/NiagaraMeshVertexFactory.ush(675,6-52): warning X3203: signed/unsigned mismatch, unsigned assumed
[SM5] /Plugin/FX/Niagara/Private/NiagaraMeshVertexFactory.ush(926,10-50): error X3018: invalid subscript 'TexCoords'
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-130811 in the post.
