Question about World Machine

[domdib]

I'm currently pondering whether to buy World Machine Standard (on sale just now), and I started playing around with WM Basic to try to get a feel for it. One thing I found intriguing was the idea that you can save not just the eroded terrain but also erosion masks, as mentioned here

However, I wasn't able to match up the terrain I generated with the erosion masks, and I wondered if there was something basic I was missing. Just to explain, I generated a .TER from a pre-existing terrain in TG2, and because it said WM Basic can only handle 513x513, that was the size of the .TER I made to import into WM. Generated the eroded terrain, plus the flow mask and then re-imported the .TER into TG2. But I'm now puzzled as to how to match up the flow mask. The obvious thing is an image map shader, but if I project through the camera, amn't I limited to an overhead view? Any thoughts from the WM gurus here would be appreciated.

Use an Image Map shader, use Plan Y projection, set the size equal to the size of the terrain in meters (you can get this info from World Machine), and that should give you a good start. You may need to adjust the position of the Image Map shader to match up, but the size should be correct.

It has been a while since I used WM (but now that I just got my upgrade to 2 ...) you might need to flip the mask... not sure but I'd check that.

Another thing to look at is in the heightfield shader, I always locate it centered, make sure the image map shader is applied on Y axis and properly positioned.

Thanks guys, I will experiment more.
