After learning more techniques from Bill from Fresh Polygons. I began to Create Multiple Modular walls.
This is the beginning of the amount of walls that has been created, and I am in the process of adding substances and materials in order to test the materials in engine.
Once the demo level is complete, I may add a new submission to the Asset store. the price may vary, but I am looking into the amount of modular assets and decide from there, here is an example of the walls, however, this is a preview. there are some tears that need to be fixed before I create the demo.
