Stripes on legs and arms when zooming out - subsurface

luca_0e1f976d66

Dear Community,
I experienced the weird effect of "stripes" appearing on legs and arms skin when zooming out a figure using SSS.

I have read several similar post and have tried moving up and down shading rate and scale but the problem remains

It has no relation with lights (with no lights at all still the problem remains).
If I remove SSS completely it disappears.

Zomming in all is perfect (see attachment 1)
Zomming out the weird effect progressively appears (see attachment 2)

Help would be highly appreciated, thanks in advance.

For the sake of clarity: this seems to be exactly my problem.

Point is I have decreased the ss shading rate (as suggested) but the problem remains.

Any other parameter I need to change?
Any other known trick?

Thanks

Did you adjust shading rate on all surfaces with the same group ID? If not it may not be using your adjusted rate - I think that's one of the settings that has to be consistent across all surfaces in a group.

Yes I did

SSS Shading rate the further away from the camera the Higher this value should be. Have you tired 128?

But if you are rendering this small that could be a contributing factor. I have seen small renders like this have issues fixed just by increasing the render size. Oh and in future can you make to examples bigger so they can be easily seen by us that need to wear glasses. :)

I have tried to reduce SS shading rate AND shading rate at the same time... the problem seems gone (or at least heavily reduced)

P.S. sorry for the small example: point is the weird effect appears ONLY with small figure, high zoom out ;) )
