Can we rasterise/cache an Object in runtime


I will give you a scenario. I have an animation of 2 dogs jumping and playing in a grass field having mountains in the backdrop. Now, 2 dogs can be vector elements but the backdrop can be converted into a raster object in runtime. By doing this, we can enhance the runtime performance on low processor devices.

I have achieved this already when I used EASEL.JS by caching the non-moving objects in runtime. So, is it possible to achieve anything similar in Lottie?
