The update notes say Spectrum is off by default and can be enabled experimentally at 8 steps; they recommend Step 600 Lighting LoRA and describe Tomato Lighting LoRA as an optional stronger-lighting setting for NSFW generations.

For full face consistency, the summary names Eros beta 4; the update also advises keeping the selected models and LoRAs for consistency.

If audio issues arise, try disabling LoRA.
