| # Sun Direction LoRA Flux 2 Klein 9B v1 |
|
|
| **Trigger word:** `match the sun direction from the reference` |
|
|
| LoRA trained to be able to move the sun to a specific elevation and rotation angle relative to the camera. |
|
|
| This lora mainly works for exteriors. |
| If the image is not an exterior, I can't assure it will work correctly as it hasn't been trained with any interior images. |
|
|
| MAKE SURE THE IMAGE YOU ARE TRYING TO CHANGE THE SUN DIRECTION DOESN'T HAVE A CLEAR LIGHT DIRECTION OR MAKE IT OVERCAST FIRST (the workflow takes care of this). |
|
|
| Basically add your OVERCAST image and the ball image as latent reference and you have it! |
|
|
| I am already working in a v2 where this intermediate overcast step is not necessary, and other stuff like light hardness, color, intensity, etc etc |
|

|
|
| This LoRA uses a ball reference image, so I created a Sphere Render Node to make easier to specify where the light comes from. |
|
|
| If you don't want to use the node, I added the blender scene to render the ball reference images in case you need it. |
|
|
| Download the Sphere Light Render Node from here: |

| ## How to use |
|
|
| The trigger sentence is: |
|
|
| `match the sun direction from the reference` |
|
|
| Feel free to add any other words needed after the trigger sentence like: "add a clear blue sky" or "keep the cloudy sky" |
|
|
| It works way way better if the image doesn't have a clear light direction, like an overcast day. |
|
|
| If the image you want to add or change the sun direction is already overcast or without a clear light direction you can deactivate the top part of the workflow. |
|
|
| The top part of the workflow generates an overcast image to be ready to apply the sun in bottom part of the workflow. |
|
|
| If you wanna do a timelapse with different light directions, generate the relight images with a fixed seed to avoid some flickering between the images. |
|
|
| Hope you like it, already working on a better v2! |
