I placed some grass assets, imported from megascans, using the unreal foliage tool(as instanced static mesh) onto my landscape and it looked fine in the editor …but when I render it using the movie render queue all the insanced static mesh grasses disappear.
any updates on this , have the same issue here.
Found a word around it , not a solid one but worked for me , before rendering erase some of ur foliage . It somehow works.
