Roblox clothing generator

Version 1 — SD 1.5 + custom LoRA

Training data: a custom set of Roblox shirt templates expanded into image/caption pairs with the rbx_shirt trigger token.
Model: Stable Diffusion 1.5 inpainting with a rank-16 LoRA trained on UNet cross-attention layers.
Structure control: SD 1.5 Lineart ControlNet and an inpaint mask preserved the fixed 585 × 559 Roblox template layout.
Runtime: PyTorch, Hugging Face Diffusers, Apple MPS for local work, and a Modal A10G FastAPI endpoint for hosted inference.

Model: Qwen Image Edit 2509 BF16 with the Qwen 2.5-VL 7B text/image encoder and Qwen VAE.
Workflow: a 24-node ComfyUI graph accepted three reference images through TextEncodeQwenImageEditPlus.
Sampling: Qwen Image Edit Lightning LoRA, eight Euler steps, CFG normalization, and the simple scheduler.
Control: ControlNet Union combined DW pose preprocessing and Depth Anything guidance for layout-aware edits.

Model: FLUX.2 Klein 4B through Diffusers, using four-step image editing on Apple Silicon MPS or a Modal L40S GPU.
Editor: a TypeScript canvas tool converts a drawn arm guide into wrapped watch geometry on the Roblox shirt template.
Generation: the browser sends a 512 × 512 crop and shape mask; FLUX refines the watch, then masked compositing protects the rest of the texture.
Preview: Next.js, React, Three.js, and an OBJ avatar provide immediate 2D texture and 3D clothing previews.
