Light ConceptsTraining data is a collection of various light concepts I enjoy using that are not overly represented in large datasets, trained as a single lora.<span style="background-color:rgb(26, 27, 30);font-family:-apple-system, BlinkMacSystemFont, &quot;Segoe UI&quot;, Roboto, Helvetica, Arial, sans-serif, &quot;Apple Color Emoji&quot;, &quot;Segoe UI Emoji&quot;;font-size:16px">ℹ️ LoRA work best when applied to the base models on which they are trained. Please read the About This Version <span style="background-color:rgb(26, 27, 30);font-family:-apple-system, BlinkMacSystemFont, &quot;Segoe UI&quot;, Roboto, Helvetica, Arial, sans-serif, &quot;Apple Color Emoji&quot;, &quot;Segoe UI Emoji&quot;;font-size:16px">on the appropriate base models and workflow/training information.I've trained many of these concepts before, generally they are nice to use to enhance the lighting of generations or give interesting effects.<span style="background-color:rgb(26, 27, 30);font-family:-apple-system, BlinkMacSystemFont, &quot;Segoe UI&quot;, Roboto, Helvetica, Arial, sans-serif, &quot;Apple Color Emoji&quot;, &quot;Segoe UI Emoji&quot;;font-size:16px">Trained on a large mixed NL and tags dataset, at mixed [1024, 1536] resolutions. Previews are mostly generated at 1024x1536 with a combination of tags and NL prompts.Concept tagsNot limited to, but collected by works containing:<pre><code>
dispersion
hue shifting
refraction
subsurface scattering
translucent

bioluminescence
caustics
dappled moonlight
glowing hot
ultraviolet light</code></pre>Works best in combination with NL if you name a character, describe their basic appearance, and finish with descriptions of light sources and their effects on the scene:<pre><code>
A vibrant and dynamic illustration of Hoshimachi Suisei from Hololive, featuring her squatting in front of a glowing triangular prism.
A beam of white light enters the prism from the left and refracts into a vibrant rainbow on the right. The background is a solid dark grey to emphasize the lighting effects.</code></pre>
