Hi Ivan,
Thanks very much for your help. I have created a post process volume that I’ve named “PostProcessVolume_ROTUNDA” but when I open the Blueprint for RainDropsRender and click on the details panel, I can’t find a way of setting this variable to access “PostProcessVolume_ROTUNDA”. Here are some screenshots that show the RainDropsRender BP and the post process volume I’ve created in the level. Do you have any suggestions for what I might try next? Thanks again.
