That's useful. Thanks Hotshot. However, being able to input values other than 10/100/1000 and 500 would be a lot useful.
Edit: Don't be fooled by the squares.
This measurement stays true only if your terrain in game engine is the same size as your render extents in WM. For example if your extents are 8kmx8km in WM your output terrain should also be 8kmx8km in the game engine. So if you have world extents like 12kmx12km in WM but import the terrain in game engine as a 8kmx8km terrain the scale you have seen by the squares goes off.
A couple of excellent approaches were discussed back in 2013 in this thread. The one I especially like is overlaying a tiling nested-square texture where you know how much "model space" each size of texture square takes up. See ivanhawkes's post in that thread.
A way to measure scale is a 'must have' feature for game makers.I have spent too much time trying to get a handle on the size of my terrain by constantly going back and forth between my game engine and WM, a single iteration of which can take 30 min. With just a few simple in game tests the hours start to really add up.
Second, (as an example). It's an 8k map I did right now and I need to know the size of that circled bump without me keep going back and fourth between WM and game engine just to find the right scales. Is that bump the size of a car? a house? a big building? Any way to figure it out?
It would be a miracle, if there was an option to drop a 6 poly box in the 3D view and move it around. The only adjustable parameter being it's x,y,z dimensions.
With the size of the box being user defined, we can finally have an excellent sense when we are creating mountains, roads, rivers, erosion etc. This is really fantastic to have a box with the size of a human or a car (or anything I'd want to fit on certain places) so I can directly move it around, rotate it like I'd do in 3Ds MAX. Basically, this feature helps to create more game-play friendly terrains by having an excellent sense of scale when we are looking at the terrain in 3D view.
Sense of scale has always been a big issue to me, specially since I create maps in various sizes.
