Nodes
Densify
Build a dense point cloud from a solve.
Turns the sparse cloud from a solve into a dense one, using OpenMVS. Auto Track in and
out.
This is the most demanding thing in the add-on. It processes every solved frame and wants a CUDA GPU with plenty of VRAM.
Settings
CUDA Acceleration uses the CUDA OpenMVS build. Needs an NVIDIA GPU.
Dense Detail controls the workload. Fusion loads every frame's depth map, so this has a large effect on both time and memory.
Density is viewport import density only. The dense PLY written to disk is always full resolution, so this just decides how much of it comes into Blender.
Max Points Import caps how many dense points are imported, evenly subsampled. Default is one million, which keeps the viewport usable.
Before Running
Run Refine Cloud first. Fewer bad points going in means fewer bad points out, and a faster run.
If you hit out-of-memory, convert the footage smaller and solve from that, or close other GPU applications. Below 6 GB of VRAM, expect trouble on large shots.
