Hi, Tappy Chicken does not use lighting. I just made the material unlit. You can change this in the material, set the lighting mode to Unlit, and run your diffuse into the emissive channel. The Chicken animation is done by offsetting the UV’s in the material. If you open the chicken material you can see how this works. You basically just tell the material how many rows there are in the texture, and then just feed it what frame number you want. I do this with a timeline. You can find it on the lower left of the Blueprint. Also, if you doing an unlit game, go to Edit/Project Setting/ Rendering and uncheck Mobile HDR. This will turn off lighting all together, and will give better performance on low end devices.
I hope this helps,
Shane
