BVFinish RAW Enhancement LoRA

BVFinish is an experimental architectural-visualization enhancement LoRA from Brick Visual, trained for FLUX.2 [klein] 9B. It is designed to refine raw architectural renders into more polished images with clearer materials, more coherent lighting, balanced color, and stronger final-render definition while preserving the original scene and composition.

This is an R&D release. Results depend on the input image, prompt, seed, and workflow settings, and should be reviewed before delivery.

Installation

Download the LoRA into your ComfyUI LoRA directory:

ComfyUI/models/loras/Klein_9B_bvfinish_v01.safetensors

Using the Hugging Face CLI:

hf download BrickMomen/raw-enhancement Klein_9B_bvfinish_v01.safetensors \
  --local-dir ComfyUI/models/loras

Recommended ComfyUI setup

1. Load FLUX.2 [klein] 9B or its FP8 single-file version.
2. Add LoraLoaderModelOnly and select Klein_9B_bvfinish_v01.safetensors.
3. Set the LoRA strength to 1.0.
4. Begin the positive prompt with the trigger token bvfinish.
5. Use the source render as the reference image for the image-to-image pass.

The validated Brick Visual workflow uses:

Setting	Value
Base checkpoint	flux-2-klein-9b-fp8.safetensors
Text encoder	qwen_3_8b_fp8mixed.safetensors
VAE	flux2-vae.safetensors
Steps	4
Sampler	Euler
Scheduler	Flux2
CFG	1.0
Working resolution	Approximately 1 megapixel, aligned to multiples of 32

The complete editor and API workflows are available in brick-momen-sirri/brick-comfy-workflows.

Prompt guidance

Start the prompt with bvfinish, then describe the scene and the desired finished appearance:

bvfinish, modern glass pavilion beside a lake, dusk lighting, realistic materials,
refined vegetation, natural color grading, polished architectural visualization

Useful prompt concepts include the building type, viewpoint, materials, landscape, time of day, lighting, and sky conditions. Describe the intended final image rather than the editing operation.

Intended use

BVFinish is focused on architectural exteriors and interiors, including raw renders, draft visualizations, landscape context, facade materials, glass, vegetation, and artificial lighting. It is intended for experimentation, look development, and workflow research.

Limitations

• The model is specialized for architectural visualization and may be less reliable on unrelated subjects.
• Strong denoise values can change geometry, signage, people, vehicles, and fine facade details.
• Generated text and small repeated structures may be inaccurate.
• The LoRA is experimental and may be updated as testing continues.
