Some of you may have used my DrawHexGrid or NoiseMaker utilities. My (free) utility program for Windows PCs called IsoTileMaker is now available at Tutorials & Utilities
Working with up to 7 textures and a mask provided by you, the program constructs a composite image and transforms it into an isometric floor, left slanting wall or right slanting wall image. The images are in the standard 2:1 iso format. Game developers and artists working in an iso format may wish to check it out.
As always, if you report a reproducible bug I will irradicate it with aggressive enthusiasm.
