Enable 'Visible in Ray Tracing' for Instanced Static Meshes

[eco_bach2]

Hi Guys. Trying to set 2 ray tracing boolean attributes on Static Mesh Instances.

1. Evaluate World Position Offset
2. Visible in Ray Tracing
   I can access the former after casting to Static Mesh Component but the latter is read only.

How do I enable ‘Visible in Ray Tracing’?

This seems like a known bug

Real-Time Ray Tracing Shadow Issue with Instanced Static Meshes

I’m experiencing the same issue. Some of my trees have shadows from ray tracing, but others in the same instanced actor do not. This issue only shows up with ray traced shadows, normal rasterized shadows work. (Currently on 4.26.2)
