Maybe not a bug, could just be me but if i create 5 matterwave emitters and pipe them out to 5 groups then tell KR to use the ALL group i see nothing in the render but it works on individual groups
Are you using a ppass all node? Can you post the scene?
Sorry just closed the scene without saving !! I simply created several matterwaves and ported out to pgroups for each one… Not the only sad git on a xmas morning then !!
could this be related to my previous bug report about two emitters?
could you try to rebuild and attach a simple scene showing your problem so I can evaluate if this indeed Krakatoa bridge related;)
