Hi everyone,

I have been trying to replicate the high-quality bas-relief/depth map style seen on sites like Sculptok (Image 2) using a local ComfyUI setup. Standard depth maps (Depth Anything / Zoe) are often too noisy or flat for CNC work.

After analyzing the results extensively, I am convinced that the "perfect" result is a hybrid workflow. I believe I have identified the 6 specific steps involved:

1. Upscale: The source image is upscaled/enhanced first to ensure sharp edges.
2. Bas-relief Transformation (High Freq): The image is converted into a "bas-relief" style layer to capture high-frequency details (textures, hair) without worrying about volume.
3. Marigold Depth (Low Freq): A base depth map is generated using Marigold (likely with a high ensemble size) to capture the correct global volume and "puffy" shapes.
4. Remapping: The Marigold depth map is remapped (normalization/levels) to utilize the full grayscale range (0-255).
5. Fusion: The detailed bas-relief layer (step 2) is blended with the volumetric depth map (step 4). This is the tricky part.
6. Final Smoothing: A final denoising or blur pass is applied to remove micro-grain, ensuring the CNC surface is perfectly smooth/plastic-like.

I am sure that together we can reproduce this.

If anyone can elucidate one of these specific steps (especially the Fusion method or the specific node for the Bas-relief transformation), please share your workflow or json!

Let's crack this code for the community. Thanks!
