Just uploaded version 0.2 to the GitHub page. Here's the changelog:
### Added
- Save Terrain as JPEG button for easier road drawing reference. (Saves normalized grayscale image to selected output folder)
- Mask Settings tab with individual blur and resolution settings for each mask.
- Check at startup to see if an small EXR file can be read. Prompt user to allow automatic install of FreeImage EXR library if needed.
### Changed
- Rearranged some of the basic and advanced settings based on the ones I use more often.
There's a bottleneck right now with blurring masks upscaled to large resolutions. Apparently doing a gaussian blur on a 50k image uses a huge amount of memory, goes into swap, and is very slow. I recommend running with low res masks until you get the heightfield right, and then turn the mask resolution up. I also definitely recommend using a color adjust after the image map to fine tune the masks.
Dune, I've talked back and forth with Cris a few times about this, but not to Matt directly. I think he's been on vacation.
