Build or load your scene + +Place lights, emissive materials, and geometry as you want them to appear in the environment. The world shader can also contribute (sky, gradients, etc.). + +## 2. Use an equirectangular panorama camera + +1. Add a **Camera** (or use the default). +2. In the **Output Properties** → **Dimensions**, set an aspect that matches a full 360° strip, e.g. **2:1** (width = 2× height), such as **4096 × 2048** or **8192 × 4096** for higher quality. +3. Select the camera → **Object Data Properties** → **Lens**: + - **Type**: **Panoramic** + - **Panorama Type**: **Equirectangular** +4. Position the camera where the “viewer” should stand (often world origin). For interiors, put it inside the room; scale/orientation of the scene should match how you want the HDRI to look. + +## 3. Render with a high dynamic range format + +1. **Render Properties** → set **Render Engine** (Cycles is typical for lighting-quality HDRIs). +2. **Output Properties** → **Output**: + - **File Format**: **OpenEXR** (best for HDR; wide industry use) or **Radiance HDR** (`.hdr`) if you need that specific format. + - For OpenEXR, use **Float (Full)** / **Half** as needed for file size vs. precision. +3. **Render** → **Render Image** (F12). You get a single equirectangular HDR frame. + +## 4. Use or share it + +- In Blender: **World** → **Surface** → **Environment Texture**, load the `.exr` or `.hdr`, set **Color Space** to match (often **Linear** for EXR used as lighting data). +- Elsewhere: many tools expect **lat-long / equirectangular** EXR or HDR for IBL. + +## Tips + +- **Samples**: raise them enough that noise is acceptable; HDRI resolution amplifies any grain. +- **Exposure**: balance in-camera or in compositing; EXR preserves headroom. +- **Seams**: avoid obvious discontinuities at the left/right wrap by keeping large emissive panels away from the seam if possible, or fix in compositing. + +If you meant **HDR stills of a normal perspective** (not a 360° diff --git a/.specstory/statistics.json b/.specstory/statistics.json index 82e26a0..4c15a34 100644 --- a/.specstory/statistics.json +++ b/.specstory/statistics.json @@ -9,6 +9,15 @@ "provider": "cursoride", "last_updated": "2026-03-31T04:58:45Z" }, + "14f1562e-b4f9-4589-b3b5-6e1e24b2c7b7": { + "user_message_count": 1, + "agent_message_count": 1, + "start_timestamp": "2026-03-30T23:00:58-06:00", + "end_timestamp": "2026-03-30T23:00:58-06:00", + "markdown_size_bytes": 2375, + "provider": "cursoride", + "last_updated": "2026-03-31T05:01:19Z" + }, "4aeb7f9e-851f-4b2a-ae52-01c07b68e74f": { "user_message_count": 5, "agent_message_count": 21, diff --git a/assets/worlds/BondingRoom_HDRI.blend b/assets/worlds/BondingRoom_HDRI.blend new file mode 100644 index 0000000..2890924 --- /dev/null +++ b/assets/worlds/BondingRoom_HDRI.blend @@ -0,0 +1,3 @@ +version https://git-lfs.github.com/spec/v1 +oid sha256:7cbdc8c7daa22e12440d5a0e499e8f9535ca1470bb86fce4a0642cbf8f6e1e9d +size 195669 diff --git a/blends/stills/BondingRoom_HDRI.blend b/blends/stills/BondingRoom_HDRI.blend new file mode 100644 index 0000000..b5a7098 --- /dev/null +++ b/blends/stills/BondingRoom_HDRI.blend @@ -0,0 +1,3 @@ +version https://git-lfs.github.com/spec/v1 +oid sha256:80e966fd29c84a3d19af914b86fc88cb41bce9c19ae079c392fe6604b948c680 +size 1029270 diff --git a/blends/stills/BondingRoom_HDRI.exr b/blends/stills/BondingRoom_HDRI.exr new file mode 100644 index 0000000..aba5720 --- /dev/null +++ b/blends/stills/BondingRoom_HDRI.exr @@ -0,0 +1,3 @@ +version https://git-lfs.github.com/spec/v1 +oid sha256:eb0ed9990e28ca1d7271e55afba3e182f743784f198052b54b6d955961c952eb +size 66433954
