How can i resize grass in MW landscape auto materials?

[HeTheFool]

Hi, im new to using unreal 5 and was wanting to make a scene with short grass. Ive used the MW Landscape and is there anyway to make the crass smaller? Ive created an island but the textures are huge compared to the island. I tried enlarging my island, however the materials just enlarge with the island object. Can someone please help? Thanks

Hi @HeTheFool, if you’re using the MW Landscape Auto Material, the grass you’re seeing is likely not hand-painted with the Foliage Tool, but rather automatically generated using the Landscape Grass Output node in the material.
That means the size of the grass is controlled through a separate asset called a Grass Type.

Here’s how to resize it:

1. Open the MW Landscape material (probably named something like M_MW_Landscape_Master).
2. Locate the node called LandscapeGrassOutput.
3. You’ll see several entries like MW_Grass_01, MW_Grass_02, etc.
4. Click the small magnifying glass next to the Grass Type to open the Grass Type asset.
5. In that asset, you’ll find Scale (Min/Max) settings lower those values (e.g., from 1.0/1.5 to 0.4–0.6) to shorten the grass.
6. Save and recompile the material the changes should take effect instantly in your landscape.

Thank you for replying. the video you shared at the part you suggested he talks about it, hes adding a different texture, not changing the size?

Also i searched master in the MWLandscape folder and get these results:

the only one that makes sense is this one:

However there is a grass modules but no LandscapeGrassOutput as you mentioned?

Can you or someone help? Thanks very much

Hello @HeTheFool, I apologize if the information I provided wasn’t helpful. Let me ask you a few questions for better understanding. What kind of MW landscape do you have? Does the landscape come with foliage, or did you add it yourself?

If you manually placed the foliage, then you have this option available in the painting section

If you pass me the landscape you are using, I can test it on my side. I look forward to your response

I wasn’t able to resize foliage I had already placed, but you can control the scale for any new foliage by using this option:

• Select your foliage asset in the Foliage tool.
• Adjust the Scale X before placing new foliage.
  
  
  
  I recommend setting a maximum scale of 0.3 and a minimum of 0.1

Again, I couldn’t find a way to resize foliage that was already placed.

If you don’t see this option, please share a screenshot of your Foliage tool panel so I can help further.
