jroy Posted August 14, 2017 Share Posted August 14, 2017 Hi all, I am encountering a problem with transformation when using popkill. When transforming inside the geometry, the simulation works fine. But when transforming at the geometry level, the simulation just disappears. Its like the object is transforming without with the particles thus treating the particles outside of it I have attached a .hip file with simple implementation of what i'm trying to do. Any help would be very appreciated. Thanks Test.hipnc Quote Link to comment Share on other sites More sharing options...
jamesr Posted August 14, 2017 Share Posted August 14, 2017 Hi! Inside your popnet, you can go to the "source_first_input" node, and under the "Source" section, change from "Use First Context Geo" to "Use Parameter Values". Set it to the source (scatter1), and check the box "use object transform". Hope this helps Quote Link to comment Share on other sites More sharing options...
jroy Posted August 14, 2017 Author Share Posted August 14, 2017 Thank you James. The file I attached was a simplified version of the main file i'm working on and the solution you mentioned works fine in the file I had attached. But using the same approach in my main file, the simulation is working but still giving some erroneous results with respect to transformation. I have no transformation inside my network but for some reason, the transformation given at the geometry level is being doubled at the pop level the reason for which i don't understand. I guess I have to investigate a bit more. Thank you for your response though. It fixed a part of my problem . Quote Link to comment Share on other sites More sharing options...
jamesr Posted August 14, 2017 Share Posted August 14, 2017 hmm, I'm sorry to hear that! I guess if it's possible, try to do your simulations around the origin, with your object transforms all zeroed out. Then parent it to a null and animate the null around. This could make it a lot easier to work. If you're working on something that has already been cached out and animated, you can try stabilizing the geo, then reapplying the transform later. If it's just something that has been animated at object level already, maybe you could try transferring the same animation to a null, do your particle sim at the origin, then parent it to the animated null. I'm not sure what's going on in your exact scene, but there's a couple suggestions. Good luck! Quote Link to comment Share on other sites More sharing options...
jroy Posted August 15, 2017 Author Share Posted August 15, 2017 Thank you again James. I have already tried something similar but without much success. Will give your suggestions a try. Quote Link to comment Share on other sites More sharing options...
