Hi guys. I really love the ability to place a terrain where you like on top of another in this new build but was wondering if there was an easy way to blend out the edges so the terrains feathered into eachother? If not, I can imagine that would be a cool thing to impliment in the next version.

Any workflow suggestions to do this would be appreciated.



Hi Glenn,

Perhaps this is what you are looking for:

Nearly an answer. i tried that first but then there is no method I can find to scale and place it on another input. The perlin noise node and image input node have a new transformation gizmo that you lose with this method. (unless there is a stand alone transfomation node I haven't found :))

I think a blur edges slider in the perlin noise node / file input node would be VERY handy.

Any further tips appreciated.



Hi there,

I'm not sure exactly what you're looking to do, but if I understand correctly I'm pretty sure it should be possible.

Are you trying to blend a File Input terrain into a Perlin Noise, or another file input? you can do both, but theres some things that are a bit simpler if its the latter not the former.

You can make it so that the perlin noise only exists in a particular (fuzzy) place by, for example, creating a radial gradient, using the Coordinate boxes to set its location, set the size of the spot that you want, and then combining it with the perlin noise in a combiner set to multiply.

does that help at all?

I guess what  I would mostly want to do is bring in a bitmap and place it at a specific position and then feather it's edges so that it blends into the terrain. If the File input had a radial/square falloff slider built into it, that would be perfect. As it stands, it's hard to import a bitmap and and combine it with a radial  grad and then place the result  on a larger map.

I would like to know if the 'transformation' and 'dimensions' stuff currently in the file input could be scripted into the combiner as well. That way I can feather the edges of an imported terrain using a radial grad in the terrain combiner and THEN scale it down and place it where I want.

Is anyone interested in scripting this? Is it hard to do? Could it be done somehow in a macro?



Regarding the Macro part:
Currently, WM1.2 does not allow you to pass parameters for position and scale of the terrain. So there isn't a way to do it automatically in a Macro. you need to create the device setup by hand, placing (transforming) the devices one-by-one.

Regarding Scripting, what do you mean? A plug in to do it? I don't know, but a plug in might be able to do it.. I'm most worried about how general such plug-in would be..
