To speed up bake-in painting for 3D models, optimize your high-poly mesh, adjust bake settings, and use GPU-accelerated tools. Simplify high-poly meshes by removing hidden faces or tiny, unnoticeable details—this reduces the data your software processes. Adjust bake settings: Lower texture resolution (e.g., 2K instead of 4K for tests) or disable non-essential maps like ambient occlusion if you don’t need them. Use GPU-accelerated software such as Substance Painter—this leverages your graphics card for faster processing. Batch process multiple assets to save time, or use a low-poly cage mesh to fix projection errors quickly instead of reworking the high-poly repeatedly.
