AST Render Tool is a lightweight Blender add-on for rendering only the frames you actually need.

Instead of rendering the full animation or manually starting separate renders, simply enter individual frames, ranges, or both:
1, 10, 25-40, 75

You can also render the entire timeline with a custom Step value.

Key Features:
+ Render individual frames and custom frame ranges;
+ Render the entire timeline with adjustable Step;
+ Works with Cycles and Eevee;
+ Supports existing Blender Compositor File Output nodes;
+ Progress, frame time, average time and ETA display;
+ Clean and simple Sidebar interface;
+ No external dependencies;
+ No additional setup required.

How It Works:
1. Install the ZIP:
Edit → Preferences → Extensions → Install from Disk

2. Open:
3D View → Sidebar → AST Render Tool

3. Enter frames, for example:
1, 10, 25-40, 75
or enable Entire Timeline.

4. Click Render Frames.

AST Render Tool uses your existing Blender render, output and Compositor settings and handles the selected frames automatically.
