I’m wondering how I can retime a vdb to slow down,stop it(frame hold) or speed it up.
The idea is to keep the match move camera movements for the e_render while changing the speed of the cached channel sets of the sim.
I tried to use e_merge (multiply) with input field 1 connected to the e_channel(velocity) and input field 2 to an e_constant (scalar) but this didn’t seem to influence the density.
Do I need to combine them in some way before they go into the e_shader (right now I just connected them to the respective density and velocity inputs)?
Now, frame hold seems to do the trick to pause the anim and I may be able to keyframe the frames of the frame hold to fake a retime but I was hoping for a more direct and elegant approach.
Also, I didn’t have time yet to test this frame hold workaround, so there might be unforeseen effects, especially due to lack of interpolation.
thanks in advance.
