natnat Posted June 12, 2017 Share Posted June 12, 2017 hey guys n girls, maybe someone can help me with my problem. i want to emit some smoke from a .obj , which is driven by an alembic (rotation/trans). Now I want to mirror it with a mirror node. allright still everything is working... , BUT if I make a smoke-sim out of it, my mirrored object emits less smoke than my original object. I allready killed the original in the mirrornode and merged it afterwards back together (not logical, but the only thing i had thought of). maybe somebody had run into that problem before and could give me a quick advise greetz natnat alembic_smoke_test.hipnc Quote Link to comment Share on other sites More sharing options...
asche Posted June 12, 2017 Share Posted June 12, 2017 Just a guess: have your tried reversing the normals on the mirrored object? Quote Link to comment Share on other sites More sharing options...
natnat Posted June 12, 2017 Author Share Posted June 12, 2017 (edited) yes, reverse / non /rev u /rev v doesn't make any other result :/ it seems like the mirrored one has not the same density like the original... screen from the fluid source node_ Edited June 12, 2017 by natnat update Quote Link to comment Share on other sites More sharing options...
Sepu Posted June 12, 2017 Share Posted June 12, 2017 working here just fine, I disable gas solvers on the shape tab just to see Quote Link to comment Share on other sites More sharing options...
natnat Posted June 12, 2017 Author Share Posted June 12, 2017 really? i disabled the solver now, but still the same problem o0 not sure what´s going on... would be weird if this problem is caused by the hardware?!? test_.mov Quote Link to comment Share on other sites More sharing options...

Sepu Posted June 12, 2017 Share Posted June 12, 2017 to be honest I might have done something else, but I cant remember now. I can download the failing file again and try. Another thing that I did I just change everything to default as well in the pyro. Quote Link to comment Share on other sites More sharing options...
Gavin Posted June 12, 2017 Share Posted June 12, 2017 (edited) Hey Attila. The difference you were seeing is because the fluid source node has noise turned on. Which means that even thought your spheres are the same, because you apply the noise after you will get two different source volumes. If you want to get them to be closer to identical then you will need to mirror them after your create your density and then mix the volumes back together.
