Hi,

The issue may be due to changing the Billboard color to a value that is outside the expected range. This can occur if you're processing the camera input further before Unreal renders it as a Billboard. For instance, adjusting values in the Adjuster panel could lead to this. I suggest turning off the Adjuster panel as a troubleshooting step:

If that doesn't resolve the issue, could you please share an image of the billboard displaying the purple discoloration?

Warmest regards,

Hi,

You should decrease the exposure in your studio camera since some of the colors are overexposed, which is most likely causing the pink dots.
If your camera has a Zebra pattern feature, consider turning it on. This feature can warn you about overexposure before it occurs.

Warmest regards,
