How can i resize grass in MW landscape auto materials?

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
