To change the sun position in Blender using a specific interactive method often associated with environment textures, you can follow a process that involves interacting directly with the texture itself. This technique, sometimes found in specialized setups or add-ons, allows you to visually pinpoint the sun's location within the environment map and then control its rotation.
Here's how you change the sun position using this method, based on the provided reference:
Understanding the Interactive Sun Control
This method relies on a visual interface where you interact with a preview of your environment texture (like an HDRI). By clicking on the apparent location of the sun within this texture, you link a sun light source to that position. Subsequent adjustments then rotate the entire environment and the linked light together.
Step-by-Step Guide to Adjusting Sun Position
Follow these steps to change the sun's direction using the texture interaction method:
- Navigate the Texture View: Use the standard Blender navigation controls within the texture preview area.
- Press and hold the Middle Mouse Button (MMB) to pan around the texture view.
- Use the Scroll Wheel to zoom in or out of the texture.
- Press and hold Ctrl + Middle Mouse Button (MMB) to adjust the exposure of the texture view, which can help in seeing details like the sun.
- Identify and Select the Sun: Zoom in on the texture preview until you can clearly see the sun's disc.
- Click the Sun's Center: Click the center of the sun within the texture using your mouse. This action locks the "sun object" (presumably a light source linked to the environment) to that specific point in the texture.
- Rotate the Environment and Light: Once the sun object is locked, you can now rotate both the texture and the light simultaneously. This is typically done using a dedicated Rotation slider provided in the interface for this specific control method. Adjusting this slider will change the overall direction of the lighting in your scene.
Key Controls for Texture Interaction
| Control | Action in Texture View | Purpose |
|---|---|---|
| Middle Mouse Button (MMB) | Pan | Move around the texture view. |
| Scroll Wheel | Zoom | Enlarge or reduce the texture view scale. |
| Ctrl + MMB | Set Exposure | Adjust view brightness for better visibility. |
| Click Sun Center | Select Sun Location | Lock the sun object to the chosen spot. |
| Rotation Slider | Rotate Texture/Light | Change the overall direction of the sun/environment. |
By using these controls and steps, you can intuitively position your sun light source based on its location within your environment texture.
