For best results, I import the weights directly. This gives me the same resolution for layers as the landscape mesh itself, and I can edit/fine-tune them later in the editor as needed.
Start-To-End Instructions
Export your snow & ground heightmaps (NOT bitmaps) from World Machine as 8-bit RAW heightmaps. Save landscape heightmap as RAW16, as usual.
Setup your material with all of the proper layer names you exported in Step 1. As you already have pictured a Ground and Snow layer, you can go to the next step.
Create a new Landscape. At the top, click “Import from File”. Choose your landscape Heightmap file.
Set the Material to the one you created in step 2.
Expand the “Layers” section. There will be 1 entry for each Layer in your material.
Assign/Create a LayerInfo for each entry. Weight-blended will mix it all to a of 1, while non-blended layers will let you paint every layer up to 1. I recommend using Weight blended, but you should ensure that your layers don’t overlap in World Machine.
Under the LayerInfo is a file listing. Select the 8-bit RAW file you created in step 1 for each corresponding entry.
Fill out any location, rotation or scale data you want, then click Import.
This will leave you with a landscape that can be painted to change any aspect, as if you had hand-painted it completely in Unreal.
Oh, and you can reimport every layer if you update your WorldMachine build. I’m currently working on a WM Macro that will help with exporting this data. Not ready to release it yet…
Here’s an example of this process:
Sorry, I forgot to update my thread. But here is my latest WM setup which is giving me this blocky version.
Earlier I was exporting the respective heightmaps for snow and ground as png. Now, I’m gonna try RAW 8 version as you suggested and see if it makes any difference.
Will let you know.
[UPDATE] I’ve tried but the .raw file crashes my editor and people at unreal suggest we use .png instead of .raw. So, if there is anything else I’m all ears.
Cheers.
