Vegetation Best Practices

Keep in mind the following best practices, recommendations, and guidelines when you add vegetation to your terrain level.

• Manually place vegetation to get the most control and best results.
• To save memory, place grass manually.
• Keep the polygon count for grass blades as low as possible.
• Do not exceed a diameter of 8 meters for grass patches. This size provides a balance between performance and coverage.
• Grasses and small plants do not require specular or opacity texture maps. For more information, see Working with Textures.
• Set the Opacity texture at a much lower resolution than the other maps.
• Use a Glossiness value of 8 or above for realistic results.
• Use the automerged method to apply wind bending effects to grass.
• Use a maximum of 72 bones per tree for touch bending.

Vegetation Recommendations

The following settings are recommended when creating vegetation in your DCC tool.

** Smaller breakable tree trunks are physicalized.

*** Larger non-breakable tree trunks are not physicalized.
