I see that you have some lines - you can use them this way: http://www.daz3d.com/forums/viewthread/16841/#248104

So in order to have variances on the X and Y axes, I have to use masks?
Also Is there a way for the resolution of the terrian/heightmap to equal the resolution of the input heightmap, instead of 512/1024 and so on?
Lastly, is there a smudge or blend tool when painting the heightmap?
I notice bryce tends to crash when trying to export a mesh with over 100 thousand triangles. Is this from my computer, or the program? IE: if somebody with a better computer tried to export it for me, would they have less of a chance of crashing?
If so, I may upload my bryce file somewhere so somebody could try exporting it at say, 500 thousand to 1 million triangles? Alternatively, is there a way for bryce to selectively lower the triangle count in areas that require less detail?
