Will check the rotation idea, although I think I already checked while looking for the soluton in distress. The temporary solution was to use PLND Deform By Strands with a grid, but it's slow and I have many many strands in the scene, hopefully not all of them have bugs (or noticeable bug). And I'm usin Redshift, but tested with MR, and I have the same bug. Probably one of these twisting rotation problem when going above 720°... I tried some Upvector tweaking too, but it was a shot in the dark.
Too bad, it's getting a bit fucked-up at render stage, the scene is really nice and shows some ice magic (you know, the one you're happy with) Anyway, if someone has an idea don't hesitate to post ;) On Wed, Sep 30, 2015 at 2:14 AM, Nono <nnois...@gmail.com> wrote: > Yes already saw that a couple of times... > Sadly I think it's a renderer specific problem of the strand orientation. > Just to check, switch to mental Ray and you will see something different. > Giving a small rotation on a second axis should fix the problems. > > Le mer. 30 sept. 2015 à 01:09, Sven Constable <sixsi_l...@imagefront.de> > a écrit : > >> Are you using mental ray?
