Light Linking in GPU rendering

Hi,

so Light Linking is working fine with Arnold CPU rendering but it seems not being supported with GPU's. Is this a known fact or am I missing something in between?

Thanks

It's a current limitation.

Quick Summary

  • Arnold GPU supports complex shading networks, SSS, hair, atmospherics, instancing, and procedurals.
  • With the same settings, GPU renders will currently be noisier than CPU renders, since GPU renders are "non-splitting" (i.e. one path per camera/AA sample). Accordingly, to achieve equivalent noise the AA sample count will need to be increased in GPU renders. Adaptive rendering is fully supported.

  • Standard Surface, Standard Hair, and Standard Volume are supported, with some limitations (see the table below).
  • OSL is supported, with some limitations currently (see below).
  • OpenVDB volumes are supported, with some limitations currently (see below).
  • Volume displacement is supported, with some limitations currently (see below).
  • Floating point textures are converted to half-float. Filename attribute tags are supported. Mipmap bias is not supported.
  • Light linking is not supported.
  • Limited AOV support.

  • Light groups, shadow groups, trace sets are not supported.
