noumiere Posted April 3, 2019 Share Posted April 3, 2019 Hi there I was following some of the Entagma tutorials on SOP solvers and I came across a minor problem shown above. How do I get the SOP solver to function on the first frame? Currently it is saying that Vdbadvect1 requires a vector, it seems to work every now and then when I disconnect it and hook it up. I remember there was a way to add a switch node on the first frame, any ideas? Thanks! Quote Link to comment Share on other sites More sharing options...
noumiere Posted April 3, 2019 Author Share Posted April 3, 2019 (edited) After multiple attempts and adding a switch node to Input one with condition $F==1 and switching to the previous frame it still doesn't work.. volumeGradient_v02.hipnc Edited April 3, 2019 by noumiere attached HIP file Quote Link to comment Share on other sites More sharing options...
vicvvsh Posted April 3, 2019 Share Posted April 3, 2019 Hi noumiere, it didn't work because of ConvertVDB. It is VDB comes in to the solver and it should be VDB as well before next substep. I moved ConvertVDB out from Solver SOP and plaice VDBsmooth at the end of node's chain into the solver. volumeGradient_v02_01.hipnc 1 Quote Link to comment Share on other sites More sharing options...
