Ok, so just updated the original post in the thread with a new version of the program. I'll just copy and paste here what I wrote in the new features thingy...
Latest version - 0.9
1) UI update. Tried to make it a little more user-friendly by making most of the common functions more apparent. Most of the important features should be tooltipped - detailed tooltips are on by default but once you know the functions you can turn them to basic tooltips or off altogether in the options menu.
2) Added an option to randomly add some light shades of grey to the mask layer. This can be useful in post imaging by using the masks as a multiply layer to add variation. On by default.
3) Added a Link Brushes option in the options menu (or CTRL+L) to hold the current ratio between Brush 1 and Brush 2. Can save valuable seconds when resizing.
4) Added a Viewport Padding variable in the bottom menu (in Advanced) to adjust the free space surrounding a forest. This has no effect when a template is loaded.
5) Added the option to view your loaded template. Located in the View menu.
6) Various bug fixes and improvements.
A few extra things I'll add here...
The default item in the bottom menu is View Angle now. This actualy does very little at the moment - it appears to change the Y density of the forest from spaced out nicely at 90 to a single line of forest at zero, with everything in between. It is hard-coded to lower the amount of rows it draw at lower values to prevent massive overdraw so that may appear odd. Basically, it is there for a future version when I change the way all the trees are placed. It can be ignored unless you want a really tightly placed forest.
Likewise, feel free to ignore the maxBrush parameters in the advanced menu.
I forgot to remove the View Control Panel option in the View menu. The plan was to have all the new controls removable but as Java seems to suck at resizing frames via code I've decided to drop this idea. You can remove the right Jitter panel with it if you like but it has little use other than that.
There are a few other commands I have disabled such as the Faux Perspective and the allignment option as they are still in development or broken in some way.
Umm, think that's about it for now.
If you have any feedback about the program then let me know here.
Cheers.
