FireAlpaca SE is design and illustration software for Windows and Mac, suitable for users of all skill levels. It provides an ad-free, faster, and more stable performance than its freeware counterpart. The software introduces a new brush engine with advanced customization, including triple brush, clipping, masking, and stipple functions, alongside enhanced watercolor parameters. FireAlpaca SE 3.0 significantly improves performance with enhanced multi-threading support for smoother operation on large canvases and multiple layers, while also minimizing memory usage. A new "MFG" filter system leverages GPU acceleration for high-speed filter processing. The application adopts a new file format with multi-threading and differential saving capabilities, supporting 16-bit color depth for professional-grade color reproduction. A "Project" feature aids in managing multi-page works like manga and illustration collections, streamlining workflow and organization. Additional unique features include a liquify tool, layer masks, special downloadable brushes, and switchable interface colors. FireAlpaca SE also retains distinctive functions from the freeware version such as timelapse recording, a programmable brush script function, 1-bit/8-bit layer support, onion skinning for animation, a materials window, and various snap functions for precise line work.
