Cullr – Render What Matters
A camera-based selection tool for optimizing individual assets by selecting only the parts visible to the camera.
I made Cullr to help me quickly clean up geometry that never shows in the final render and to prevent VRAM from maxing out when subdividing heavily.
When working with layered photogrammetry, like stacking mountain scans, there’s often a ton of hidden junk underneath. Manually selecting and deleting takes forever. With Cullr, I can just select what the camera actually sees and clean the rest out in seconds.
Same goes for subdivision. When I’m prepping an asset for close-up displacement, I only want to subdivide the parts that are actually visible to the camera. Cullr helps me do exactly that—precisely and non-destructively. I’d rather put those millions of polygons where they really count: into crisp, detailed subdivisions.
Cullr is for you if...
| ✅ | You work with photo-scanned assets and need to remove hidden or overlapping geometry. |
| ✅ | You want your subdivisions to go exactly where they matter—on the parts visible to the camera, and nowhere else. |
| ✅ | You want to get the most out of every polygon—leaner scenes, faster renders, and zero wasted geometry. |
Two Big Use Cases
✂️ Cleanup
Let’s say you’ve stacked a bunch of scanned mountain assets to build a landscape. It looks great—but underneath, there’s loads of hidden junk geometry. With Cullr, you fire rays from the camera, define your own occluders, and select only what’s actually visible. Then you get rid of the rest. The results are clean, optimized assets that are ready to go.
🎯 Subdivision Where It Counts
Imagine prepping an asset for close-up displacement. Cullr lets you mask and isolate only the visible geometry across an entire frame range—so you can subdivide and displace just the visible area. You can easily save millions of polygons this way, especially when working with high subdivision counts.
