Hi

Can someone tell me how to change the scale of the pyro fx grid. do you change the scale of autodop network tool. upResPyro tool or lowResPyro tool ??
cause each of these tools have size parameter. I tried changing and keeping the size of these tools same but the smoke looks compressed and stretched out.

thanks

the size parms represent the container “size”. These should be similar low and up res. you can scale your simulation afterwards by appending a transform SOP. Same as you would with any other piece of geometry.

Hi fsimerey

Thanks for the link. he only scaled the low res and before simulation.

Hi cklosters

Thanks for the reply. i just couldnt find the transform SOP. Can i use null or subnet utility and link it with autodop, low and upres?
ler say if i scale down these 3 tools manually, would that change the resolution of my grid/container.
