Hello all,  
As per title I’d like to exclude one mesh from Lumen screen traces.  
I know that this can be done _globally_ by using the command :  
r.Lumen.ScreenProbeGather.ScreenTraces 0  
although I don’t want to have such a global effect.  
Would it be possible to do it specifically for one mesh(es)?  
Thank you 🙂

Hi, I don’t think it’s exactly what you’re looking for, but you can disable raytracing for individual static meshes with the “Visible in Raytracing” flag.
