Whats the best way to filling any shape full of smoke (billowy smoke)

I have tried ployextrude “method” but i get leeks and i all so“ tried collide with objects” (scatter) but does not fill the “contours of the shape” very well look like “very blockly voxel graphics ”

is there more accurate way of filling objects with smoke ?

Try this: create your static collision object, animated or still, and then invert the sdf (Collisions tab > Volume > Invert Sign).

thank you so much getting back so quickly


could you break it down bit more for me, I only been learning Houdini for last 4 days and 4 days only

Here's a hip file that explains it; let me know if you have some questions about it!

Thank you so much, i really do appreciate your help

I understand know and found the “Invert Sign”

the .hipnc file was useful

The sticky's were very clear explaining whats was going on

thanks aging for taken the time to explain it to me
