Niagara Error reading mesh colors

Hi people,

I’m setting up a Niagara emitter which sample a static mesh and then use the static mesh location to spawn from its surface. The particle works, but it’s throwing away the same message on the log every time the particle loops.

LogNiagara: Static Mesh data interface is cannot run as it’s reading color data on a mesh that does not provide it

The mesh has CPU access enabled so don’t understand why it is complaining about.

Any ideas?
