1. What is the Blender Render Time Calculator?

The Blender Render Time Calculator estimates how long a render will take based on your scene's resolution, number of samples, and your GPU's performance. This helps in planning rendering projects and optimizing settings.

2. How Does the Calculator Work?

The calculator uses the render time equation:

Where:

• \( \text{Resolution} \) — Total pixel count of your render (width × height)
• \( \text{Samples} \) — Number of samples per pixel
• \( \text{GPU Performance} \) — Your GPU's rendering performance in units (benchmark your GPU to find this value)

Explanation: The equation calculates total computational work (pixels × samples) divided by your GPU's processing power.

3. Importance of Render Time Calculation

Details: Accurate render time estimation helps with project planning, deadline management, and optimizing render settings to balance quality and time.

4. Using the Calculator

Tips: Enter resolution as total pixels (width × height), your desired samples count, and your GPU's performance value. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How do I find my GPU performance value?
A: Run a benchmark render in Blender and calculate performance as (resolution × samples)/time.

Q2: Does this account for CPU rendering?
A: No, this calculator is specifically for GPU rendering. CPU rendering would require different performance metrics.

Q3: Why is actual render time sometimes different?
A: Scene complexity, memory limitations, and other system processes can affect actual render times.

Q4: Can I use this for animations?
A: Yes, multiply the result by your frame count to estimate total animation render time.

Q5: How accurate is this estimate?
A: It provides a baseline estimate. For precise timing, do test renders with your actual scene.
