squardis Posted July 8, 2016 Share Posted July 8, 2016 Hi, Im trying to do some debris on a simple falling object. Now when i import my geometry and particles emitter source they are below the groundplane and shifted. Any idea how? Outside my popnet in the OUT_DEBRIS_EMITTER its just at the correct location. something shifts the position in the popnetwork THNX Quote Link to comment Share on other sites More sharing options...

squardis Posted July 8, 2016 Author Share Posted July 8, 2016 No thats not it, even my groundplane is below the grid origin. I began a new scene en it is fine now. except that my particles goes through my groundplane. How is that possible? Quote Link to comment Share on other sites More sharing options...
Farmfield Posted July 8, 2016 Share Posted July 8, 2016 Check your object position and/or your ground plane position - and I mean at an object level. SOP level lives in object coordinates, so when stuff like this happens, it might be you happened to move something at object level. Quote Link to comment Share on other sites More sharing options...
squardis Posted July 8, 2016 Author Share Posted July 8, 2016 Nope, Im all working in One and the same object level so thats not it testDebris.hip Quote Link to comment Share on other sites More sharing options...
Farmfield Posted July 8, 2016 Share Posted July 8, 2016 Yeah, you are copying an object offset from 0,0,0 onto each particle and as it aligns both position and rotation, an up-side-down particle will place the offset object as far in -Y as it was up in Y fed into the copy SOP. 1 Quote Link to comment Share on other sites More sharing options...
6ril Posted July 8, 2016 Share Posted July 8, 2016 just had a quick look, and it seems to be fine. point1 node is moving your particles under the ground (-0.1 in y) so move them to zero instead ? If you want flat on ground debris. also, the geo you are copying on the particles got an offset... check it by replacing it by a sphere, you'll see. 1 Quote Link to comment Share on other sites More sharing options...
