Terrain Slice and Combine Tool

We are trying to build something that’s pretty simple. 1. We have four biome sheets. Forest, grassland, lake region, mountains. 2. We need a tool to slice a rectangular piece like a cookie cutter from the master biome sheet. 3. The size of the rectangular cut should be adjustable. 4. We choose two pieces cut from a random spot of two of the biome sheets. 5. Create a tool that can cut like a jigsaw puzzle so both biomes have opposite side of the same cut. 6. We cut the edge of both biomes like a jigsaw puzzle and piece the two together perfectly to intentionally create a jagged irregular line instead of a straight line. 6. Ultimately, we should be able to take trees and lakes, and other stuff too cover the jagged line, so it looks natural. 7. Repeat until the chosen amount of biomes is complete. 8. Automate this entire process. That’s it. That is the tool. We want to create an automate. We already have the biomes. We just need to make the tools, and automate the process. You are not creating any grayscale masks or binary masks. They are all created. We just need you to align them with the art so they all cut together at the same time. We are also not asking you to do any artwork at all the art is done. Please apply if you are qualified for this. Let us know approximately how long it would take and approximately how much money. Thank you.
