High-dynamic range images (HDRI) are a type of image that captures a wide range of light and dark values, making them ideal for use in 3D rendering and lighting. Traditionally, HDRI maps have been created by taking multiple photographs of a scene at different exposures and then stitching them together. However, this process can be time-consuming and difficult, especially if you are trying to create a custom HDRI map.
Recently, there has been a growing interest in using AI to create HDRI maps. One of the most promising AI models for this task is Stable Diffusion, a text-to-image diffusion model that can be used to generate high-quality images from text descriptions.
In this article, we will show you how to use Stable Diffusion and other proprietary AI models to create custom HDRI maps. We will also discuss some of the benefits and limitations of using AI for this task.
How To Make Custom HDRI with AI
Blockade Labs
Blockade Labs’ flagship product, Skybox AI, is a web-based tool that allows users to generate HDRI skyboxes using simple text prompts. Users can enter any type of prompt, such as “sunset over the ocean” or “aurora borealis sky,” and Skybox AI will generate a high-quality HDRI skybox that matches the description.
Skybox AI is incredibly easy to use, and it can generate HDRI skyboxes in seconds. This makes it a valuable tool for artists and creative professionals of all skill levels.
Blockade Labs Skybox AI has a free tier that allows users to generate up to 15 skyboxes per month and has watermark. The paid tier costs $120 per year and includes unlimited skyboxes, unwatermarked exports, and commercial use. Blockade Labs also offers an enterprise plan with tailored pricing for users who need even more features and support.
Stable Diffusion or XL
Stable Diffusion is a text-to-image diffusion model created by Stability AI. It is a powerful tool that can be used to generate realistic and creative images from text descriptions. It is not easy to create HDRI directly with simple prompts in Stable Diffusion. However, there are a few workarounds that can be used to generate HDRI images.
Step 1.
Download a Decent generalist Stable Diffusion model from the provided link, and after you’ve done that download a model which you like from civitai.com.
Step 2.
After you’ve downloaded stable diffusion and the model. Download any generalist model , and consider downloading any sdxl model as it has more parameters and can do most styles also you can try “hdri_panorama_view” LoRA, this LoRA allows you to generate HDRI easily. And after downloading this put this LoRA inside lora folder of your preferred interface: Lora. And after doing this you should be able to see this LoRA inside the LoRA tab of your preferred UI.
Step 3.
After downloading you should be ready to go, but before you start writing your prompt you should set your image resolution to 512 by 1024. After you have done that, write what you want to be generated.
Set the size to something around 1544 x 772, or 1244 x 622, and in prompt put things like seamless.
Step 4.
What ever interface you are using you can do it in almost in all, including automatic 1111, comfy ui, and invoke ui.
