I'm just documenting building a terrain, everyone else who has dropped bombs in here decided they didn't like what I was doing. Or tried to hijack my design to have me build their terrain without having to expend the effort themselves. These forums only being a few steps above 4chan at times controlled by the rule# and Skuzzy intervention, I've found the only method to deter them is a ten ton hammer named "Look Don't Touch". I did not make it that way, I've only been "documenting" building a terrain. If anyone really wants to communicate terrain building with me, they use the PM system. If it's done in the public posts, often much can be gotten away with including simply trying to throw a wet blanket on someone they don't like within the boundary's of the rule#.
So why do "they" have the impulsive urge to derail what I'm doing? This being the Internet, negative peer responses are supposed to effect you to help you not to want to go on. Since forums are peer and tribal driven.
Back to what I was documenting.
The bulldozer tool is good for moving around the polymesh and has limitations when you need more than straight lines of material effected. Knowing what the smallest brush width is that will control one polygon will allow you to use the raise hill tool as a cutting or raising tool to rapidly shape compound shapes. Running the Smooth Catmul back through the area allows you to move through faster becasue it will clean up tiny inconsistencies.
This is about one sector of rapid carving with that tiny brush diameter in 15 minutes. The gorge runs another sector and then I will finish with the Smooth Catmul and make the brush 2x the diameter in the picture. Making it larger will magnify the effect and deform things in too uniform of an application. The smaller brush allows rapidly running across all the formations and controlling the amount of deformation. It helps to google rock formations like this to get a feel for how they weather and deform in the real world. The size of the terrain editor polygons limit making things look realistic to about this. Once you understand that limitation, it speeds up building topo features since you know when to stop and move on.
