Advanced search tips: use spaces to require multiple terms (AND), | for alternatives (OR), wrap phrases in quotes (="a b"), =term for exact match, 'term to include, !term to exclude, ^term to match prefix, !^term to exclude prefix, .ext$ to match suffix, and !.ext$ to exclude suffix.

query_light_probe

#

This is the version that’s used when storage buffers aren’t available and light probes aren’t clustered. It simply does a brute force search of all light probes. Because platforms without sufficient SSBO bindings typically lack bindless shaders, there will usually only be one of each type of light probe present anyway.
