<h2>360 Diffusion v1</h2>Posted first on <a target="_blank" rel="ugc" href="https://huggingface.co/ProGamerGov/360-Diffusion-LoRA-sd-v1-5">HuggingFace</a>.This <a target="_blank" rel="ugc" href="https://arxiv.org/abs/2106.09685">LoRA</a> model was finetuned on an extremely diverse dataset of 360° equirectangular projections with 2104 captioned training images, using the <a target="_blank" rel="ugc" href="https://huggingface.co/runwayml/stable-diffusion-v1-5">Stable Diffusion v1-5 model</a>.This model was finetuned with the trigger word qxj. If using the <a target="_blank" rel="ugc" href="https://github.com/AUTOMATIC1111/stable-diffusion-webui">AUTOMATIC1111 WebUI</a>, then you will have to append <code>&lt;lora:360Diffusion_v1:1&gt;</code> to the prompt as well in order to activate the model.<h3>Rendering Tips</h3>When rendering, it is recommended that you use either a 1:2 ratio or a perfect square. Rendering as a 1:1 square can help improve concept coherence (like the walls of a room).Details can lose coherence at large sizes with txt2img, so it is recommended that you initially render a smaller version with at least one dimension near 512px, and then upscale it with img2img (with denoising set to 0.5) or a built in high-res fix feature.Details can sometimes be improved by looping the output back through img2img multiple times, with a denoising of 0.5 and seed resizing.<h3>Seam Handling</h3>As Stable Diffusion only renders squares and rectangles, any equirectangular projections will have edges that may not fully match the other side. While these seams are generally pretty minimal, there are multiple ways to deal with them:* Using the <a target="_blank" rel="ugc" href="https://github.com/tjm35/asymmetric-tiling-sd-webui">asymmetric-tiling</a> extension's x-axis tiling feature can help eliminate seams entirely, but the extension can significantly degrade output. It is recommended that you set the 'Start tiling from step N' setting to start at around 50% in order to minimize the impact (ex: start at 9 if using 20 steps).* Inpainting can be used across the seam after shifting the image horizontally to the right or left.* <a target="_blank" rel="ugc" href="https://www.gimp.org/">GIMP</a> (potentially with <a target="_blank" rel="ugc" href="https://gmic.eu/">G'MIC</a>) or Photoshop can be used to remove the seams.<h2>Useful Tags</h2>In order to improve usability of the model, various words and phrases were used to tag objects, scenes, styles, and content.

Therefore, the following viewers are recommended:Website (supports VR headsets): <a target="_blank" rel="ugc" href="https://renderstuff.com/tools/360-panorama-web-viewer/">https://renderstuff.com/tools/360-panorama-web-viewer/</a>AUTOMATIC1111 WebUI Extension: <a target="_blank" rel="ugc" href="https://github.com/GeorgLegato/sd-webui-panorama-viewer">https://github.com/GeorgLegato/sd-webui-panorama-viewer</a>WebUI Extension for converting your renders to stereoscopic 3D images: <a target="_blank" rel="ugc" href="https://github.com/thygate/stable-diffusion-webui-depthmap-script">https://github.com/thygate/stable-diffusion-webui-depthmap-script</a><h2>Example Image Models</h2>The example images used the following models:- Landscape renders used: <a target="_blank" rel="ugc" href="https://civarchive.com/models/4384/dreamshaper">https://civarchive.com/models/4384/dreamshaper</a>- Renders of people used: <a target="_blank" rel="ugc" href="https://civarchive.com/models/4823/deliberate">https://civarchive.com/models/4823/deliberate</a>
