caustics flickering issue

[squintnic]

I haven't used caustics much in ages and have an animation to do with them but getting some flickering and strobing with them, mesh is a phoenix mesh, caustics generated by a direct light on 4500 subdivs, 0.1m search dist, 100 max photons and direct vis turned on.

rest of the scene is lit with a vray sun/sky BF/LC 1500 subdivs, 2.0 retrace and 1/32. 0.03 threshold

anyone got any advice here?

cheers

To reduce flickering increase LC Subdivs to 3000 and Retrace to 8.0
