Decals disappearing on sequence play

Hi everyone!

I have a decal sitting on a Static Mesh, and a test Cube mesh (default cube actor), and it disappears on all my test models when I hit Play on the Sequencer.

I’ve created a scene with the intention of rendering it out to a MOV eventually, and am avoiding baking lighting or compiling, and I’ve worked this way for VR. I’m not ultra experienced with Unreal, but have managed to make a cool scene with lots of Geometry Caches and imported models. Lighting is mainly a day to night sequence, and some dynamic lights. My sequence’s finale has a bunch of decals appearing on a geometry cache and regular static model (landscape model). I had deferred decals set up to toggle visibility in the sequencer, but they don’t even show up.

I’ve tried DBuffer decals as this seemed like a solution to other decal rendering problems.

Does this mean I have to suck it up and build lighting to make decals work?

Thank you!
