Nearly-Seamless HDR Latlong
The lightweight, single-graph route to an IBL: an SDXL img2img with a View360 LoRA on a 2:1 canvas, made to wrap nearly seamlessly with circular VAE + seamless tiling, then HDR-expanded so only real light sources glow. Not a true 360° world-gen — for that, see the HunyuanWorld pipeline in VFX Tools.

How It Works
The one-graph way to get a usable image-based light out of a single photo, without a multi-process pipeline. SDXL runs img2img off your plate on a 1536×768 (2:1) canvas with a View360 LoRA, and circular VAE + seamless tiling (horizontal only) make the left and right edges wrap nearly seamlessly so it reads as a latlong — good enough for fill and reflections, though a faint seam can survive on tricky plates.
What this is and isn't. It keeps most of your input (0.5 denoise) and makes it wrap and HDR-expand — it does not outpaint to full 360°×180° spherical coverage or reconstruct the poles. It's fast, it's a single drag-in graph, and it's a genuinely useful IBL. When you need a true 360 built out from one plate — with the seam actually healed — that's the HunyuanWorld → ComfyUI → emitter-gate pipeline shipping in the VFX Tools app, not this graph.
The emitter logic is the shared idea across both: if you just brighten the bright spots, everything pale starts to glow — white flowers, a bright window, a light rock — and your scene ends up lit by a daisy. So before adding any glow it decides what's actually sky and sun versus a merely light-coloured object, and lets only the real emitters shine.
