can't render "warning motion tile cannot allocate a buffer larger than 30000 pixels in either..

I would have to see your comp and probably a flow chart to give you meaningful suggestions. It is almost always possible to work around the size limitations.

There are a lot of posts with the same error in the community forums. Motion Tile can reach the limits of After Effects if you use bigger images or bigger values for repetitions so you can start reducing the number of repetitions or checking if you can create an alternate smaller version of your filtered image.
