Problem with ILCQ Volume

In my scene, I created wall from single staticmesh (Shown in figure 1) by duplicating mesh and placing it side by side. There are total ** 4000 staticmesh objects**. I set these static meshes mobility to movable. I set the indirect lighting cache to ICLQ Volume.

Figure 1 :

Figure 2:

Figure 2 indicate the editor view of the wall. Without any problem. Working perfectly.

Figure 3:

Figure 3 indicate the play in editor view of the wall with bright purple (random) light.

I tried with Volume light sample placement scale = 0.1, 0.3, 0.4, 0.5, 0.7, and 1. But result is same.

Hey ,

Could you provide me with your test asset so I can reproduce this in a new engine version?

If you would like, you can also test in a more recent version, as 4.8 is an older version and we need to verify this still occurs in a more recent build to enter a bug report.

Thank you,
