Knowing how much memory Gaea will need for your project helps avoid performance issues and crashes. Here’s a simplified approach to understanding memory requirements in Gaea.
Understanding Memory Needs
Memory Demand: The more complex and detailed your terrain, the more memory it requires.
Factors Affecting Memory: Resolution, node complexity, and layering all influence memory usage.
Impact of Resolution: Higher resolutions consume more memory. A 2048x2048 resolution needs significantly less memory than an 8192x8192 resolution.
General Rule: Doubling the resolution quadruples memory usage. For example, going from 1024x1024 to 2048x2048 will increase memory requirements fourfold.
Heightfield: The 3D representation of your terrain in Gaea.
Memory Calculation:
Memory required = Resolution (width x height) x Bit Depth
Gaea uses 32-bit heightfields for high precision.
Example: For a 1024x1024 resolution with 32-bit depth:
1024 x 1024 x 4 bytes = ~4 MB
Nodes: Each node in Gaea represents an action or modification. More nodes mean more memory.
Layering: Stacking multiple layers adds depth but also increases memory requirements.
Plan for Headroom: Keep at least 25-30% of your system’s RAM free to ensure smooth performance.
Memory-Saving Tips: Use lower resolutions and simpler nodes while experimenting. Gradually increase complexity as your project nears completion.
Export Size: The larger the resolution at export, the more memory you’ll need during that process.
Preview Exports: Try lower resolutions for test exports to verify results before the final high-resolution export.
Start with Lower Resolutions: Build your terrain in 1024x1024 and increase resolution as needed.
Simplify Your Node Graph: Fewer nodes use less memory. Start with basic nodes and add detail as you go.
Keep Track of Available Memory: Regularly check your system’s memory usage to prevent overloads.
With these tips, you’ll be better prepared to manage memory efficiently in Gaea and ensure smoother workflows and stable project builds.
