Preview a mask (heightfield) in 3-D overlay

hello,

maybe some folks can help me out:

I got a lot of “masks” in my WM file, that I want to preview in 3D, not only 2D.
The thing is, I use selectors for height and slope, sometimes both, to generate a mask (which is a heightfield, of course)

Now, instead of going thru the process of exporting these to .png for example and re-load/bring them in via File Input node (interpret as RGB), is there a
way to have the b&w mask somehow “converted” into bitmap, to connect to an overview, so I can see “live” changes to the mask on the 3D terrain?

best regards

I think you can just feed the mask into the overlay texture input.

In the overlay view settings choose “Blend colors with mask” at full intensity

hey, thanks for reply!

but the outcome of the mask is a heightfield, not a bitmap - Overlay view got two slots: 1 for Bitmap, 1 for heightfield - and I can only connect to the heightfield-slot…
maybe I was not clear on that?

If you connect a heightfield to a (slope) selector, then you see a b&w mask, if you focus on the selector - I want this"mask" from inside that selector
to be shown as a 3D model (b&w), so I can see better, what the result will look like.

Inside the selector, everything is 2D only…

Weird, I can connect a height map to the overlay bitmap input on my World Machine, if it doesn’t work try feeding the mask into a gradient device with a standard black to white gradient and feeding that gradient into the overlay.

Or if you want to display your mask as a 3D model try feeding it into a displacement device with 0 strength

thanks for the hints, will test it !

WoW ! All 3 Methods are working :slight_smile:

Thanks a lot!!

only thing is, it does not work, like I expected it :wink:

basically, I want the “mask” I generate via the height-selector to be projected onto the heightfield as a texture.
so I can see exactly, where white and black areas will be on the terrain

when I use the methodes, you described - I just get some distorted geometry in 3D view

So I guess, only way is export the mask as bitmap and reload with File-input and connect to overlay…

Sorry - My fault!!!

It works now, I just connected wrong heightfield XD

I can just connect mask to bitmap slot and heightfield to heightfield in overview
