Bakerman brings easy and extensible in-editor texture asset creation. Conveniently use Bakerman to generate, manipulate or blend textures from within Unreal Editor.
Through editor utility scripts you can select textures and re-bake them via a filter material, generate entirely new textures from generator materials or blend and bake two existing textures through a blend material.
If you want to have more control over the generation / manipulation or blending, simply copy or instance a material and configure it to your liking. If you want to even more advanced - Bakerman let's you easily create materials yourself and let them be used in the baking process.
