In this quick workflow we will focus on using the rendering from the same Seed. We will start with generating a few renderings, then walk through some examples of how you can use seed to generate more predictable results.
Step 1: Open Veras
The first step of any rendering is framing up the view. Once we have that lets launch Veras
Step 2: Get started with a prompt
Through this workflow I am going to leverage Seed to demonstrate what aspects of the rendering will stay consistent. Seed is a powerful tool that will help you hone in on the rendering you are looking to create.
I used the following settings:
Atmospheric
Prompt: "cabin in the woods, large windows with white trim, during rain, tall grass,"
Geometry Override: 14
Material Override: 100
Prompt Strength: 60
Render Engine: Version 6 Sharp
Step 3: Enable Seed and Update the prompt
Next, I enable seed in each view and add a color before the word cabin. In each example note the consistency of the surrounding forest. When Seed is enabled, and we make only a minor change to a setting or prompt the resulting image should be very similar. The larger the change the less predictable the outcome will be.
Step 4: Use Seed to better understand settings
In the example below I have first created a Rendering, then locked in seed and adjusted the Material Override. First showing a value of 100, then working down to 0 with increments of 25. Notice as the setting gets lower the result gets closer to the base SketchUp view.
We can run the same experiment with Prompt Strength. Here you'll notice that the contrast and saturation of the image gets flatter as the value goes down.
Again, the same experiment but with Geometry Override. As the value is increased the rendered output will get further and further from the source view.
All three are a balance and the reaction is amplified by the settings of the others. 10 more in Geometry Override will have a stronger effect on the image if Prompt Strength is set to 100 than it would if it was set to 50.
Step 5: Use Seed while changing your model
Last let's make some changes to our model without changing the view angle. Where the scene is still very similar the seed number will be able to hold the solution and result in a very consistent image.
Conclusion
Adjusting your settings can feel a bit like chasing your tail. With the Seed, we can lock in the solution so that adjustments to our settings will have a more predictable change in the rendered image. With that control we can refine our prompt and settings to exactly the result we are looking for. To try Veras for yourself, you can download it here: www.evolvelab.io/veras
