Unreal Engine Event Graph Node Logic

---

---

I have built a randomized camera and lighting system in Unreal Engine 5.5.4 using Blueprints, where I generate a list of randomized transforms ahead of time (camera location, rotation, and light color) and want to capture two screenshots per transform: one RGB image (normal materials) and one segmentation mask (special per-actor materials). The core issue is correctly sequencing the captures: I need to first move the camera and lighting based on the current transform, then take the RGB screenshot, then switch all actors to their segmentation materials, then take the mask screenshot, then move to the next transform, and repeat this cleanly for all shots. The problem I'm running into is that Unreal’s Delay nodes, timers, and material switching don't behave properly if not carefully managed — sometimes captures happen with the wrong materials or things overlap. I need help implementing a reliable, frame-safe method to move the camera, take the RGB, swap materials, take the mask, and then loop to the next step, ensuring correct timing and image separation. I have almost all of the setup complete (structs, random transform generation, material setup), but I need guidance wiring the control flow cleanly and professionally so it works every time.
