We want groom strands enabled only for VIP characters in cinematics on high-end hardware, falling back to hair cards in other instances. What is the proper way to handle this?
Should we have strands at LOD0 and force that in cinematics and otherwise default to LOD bias 1? Or is there a way to globally disable strands and have a groom component fallback to the lowest LOD card asset that is available?

Hello,
Thank you for reaching out.
Groom supports Strands, Cards, and Meshes all on the same LOD.
When creating LODs, the default rendering method is selected on the LOD tab of the Groom editor:

When adding Cards, or Meshes, the LOD can be selected for that mesh:

The CVar “r.HairStrands.UseCardsInsteadOfStrands” which will force the use of Cards (if available in the asset) instead of Strands when enabled. Keep in mind that any LOD that does not have Cards will become invisible while this CVar is enabled.
Please let us know if this helps.
