Created a profile page for updates on my Voxel Dungeon Crawler.
Its still being made with EvalDraw until I can find an alternate method of rendering voxels, but so far its the fastest despite the limits.
Also the limits provide interesting art challanges, like no alpha or lighting.
The tools I'm making for it are still being made in GLBasic, although my image to voxel converter needs a reworking, it tends to have problems loading large animation strips or images in general. I plan on working around this by only supporting BMP files and reading from the file instead of loading it into memory. But thats for some time later.
The second tool is a map maker which is coming along nicely, rather simple too. Still need to add placement for objects, lights, entities and events.
The project is also open source for all to play with, Evaldraw isn't too hard to work with and in later releases I'll have some tutorials and templates to work with.
