Hello guys,
I have question about render with out geo but keep the alpha. I have a explosion effect around rocket. I only want to render explosion but keep geo light effect and shape to be alpha which can use in Nuke to put rocket render. I use constant shader, in the render rocket it change to black but in alpha chanle it still balck. How you guys slove the question during render?
Thank you!

Hi guys, I try to make a explosion in a box. After explosion, box air will burn out and create a force can drag smoke back to box. I have no idea how to make it. It like have different direction for drag back? Can someone help me out?

Hey guys,
I am working rocket launch simulation which i used pyro solver to do it. In the reference, less smoke will keep 20 frame then the explosion will suddenly happened and after 10 frame explosion will cool down and push back into the bottom of rocket. I used key velocity in fluid source to do push back part, but result is not good. Do you guys have some ideas about doing push back part?
this is reference

Hey guys,
I try to give a my pyro solver simulation a go down wind force during the mid of time, I used expression to let when frame after 50 frames force change to 100, but it doesn't work. Do you guys have some ideas to fix this problem.?

I am new for houdini. I got a model, then I used add sop to delete geo but keep the point, then i want to connect points to a curve. I don't know how can i choose point from add sop. There are around 600 points in the sense, so I use group sop for the point, but I found out I cannot choose the group in the curve coordinates. Do your guys a have some idea?

I build a new parameter and try to connect with my ../obj/sphere/front1/file. I don't know how to make a list or how to connect them.
