Texture Maker is a web-based application that enables users to quickly and easily create and customize textures for 3D models, visual effects, and any other digital artwork. The app provides a wide range of tools for creating textures from scratch, including a library of over 500 textures and more than 500 patterns, shapes, and brushes. The intuitive interface allows users to quickly customize their textures with a variety of filters, color adjustments, and other effects. The app also offers support for 3D model formats, letting users import 3D models and apply their textures to them. With Texture Maker, users can quickly create professional-looking textures for their projects without needing to learn advanced graphics software.
NeoTextureEdit has excellent options that sometimes may seem limited, but once you learn how to use the nodes, you can do anything. And it's easy to export maps for unreal and maya.
