Splatmap Problems

Hi there,
first of all I wanted to say that World Machine is a really great Tool to work with, and at the moment I’m starting to get the hang of the features and really enjoying it so far. I started looking through the help files to get a better Idea of what I’m doing.

I found the island creation and worked a bit with the sliders and forms to get a shape that was on my mind. Nothing to special of course as I’m just starting out. After creation of the island I tried adding the creation of a Splat-, Normal- and Heightmap and to be able to export the terrain into Unity.

Problem:
I got the Splatmap working and it seems to be picking up the heights, but somehow not for the Main island itself. I tried adjusting the claps to a different height, and even used another constant to raise the whole island up further (not in the pictures anymore as I removed it), but the splatmap remains the same. After importing the terrain into Unity the heights all seem to be fine, the Island is raised as it should just the splat looks weird.
I would really appreciate it if someone had some kind of hint what my problem may be here. Thanks

Also added some pictures, give a better look at what my problem is.

Hi there,

A couple things:

  1. First, look at the output of each of your selectors and make sure that your masks are selecting the right area – there’s no way to get the right output if the selectors are not selecting what you want.

On this vein, how do you want the height splat to behave? Do you want the height splat layer to only be active in the uppermost parts of the map? Make sure your selector is set appropriately.

  1. If your selection masks are OK, then the problem is probably in how the splatmap converter is handling the areas where multiple maps are at full strength. Open up the splat converter and look at the Priority mode. What is it set to?

For example, if its set to “Favor top inputs”, then in areas where multiple maps have strong values, the height coverage input (the top input) will win. If it’s set to Bottom inputs, then the heights will be prioritized last. Manipulating this might be able to get you what you want.

Hi Remnant, first of all thanks alot for the quick reply. It was extremly useful and helped quite a bit. As it turned out you were absolutely right about the selectors being the problem. I didn’t adjust the falloff quite right, which was giving me a lot of headache. Thanks to you I got that problem solved. Now its just a matter of tweaking the inputs a bit and everything should work out as planned. Thanks again
