The Gas Repeat Solver seams to have changed in Houdini 12.5. It previously had two inputs, on accepting an object and one multi input that accept a bunch of solvers. In houdini 12.5 it only have the second multi-type input.

What is the reason for this change? Could it possibly be a misstake/bug?

I've been using the gas repeat solver with various gas Solver nodes at the first input to dynamicly “speed up” simulations at different stages. To get the same result now I need to unlock the pyro solver node etc. to place my repeat solvers at a lower level. This doesn't seam right.

I can get the same result if I unlock the pyrosolver, unlock the smokesolver and then stick the gas repeat solver into the solver inputs. However I don't really like to unlock and modify assests.

I wonder if taking away the first input is a active choise from sidefx or just a bug…

I've noticed that the Gas Repeat Solver have changed from Houdini 12 to 12.5. Going from having two inputs “Objects to be Processed” and a multi input accepting a bunch of different solvers.

In h12 I've used it a bunch of times by connecting my pyro solver to the first input and have the gas repeat solver re-process the incomming pyrosolver multiple times.

This doesn't work anymore since the only remaining input doesn't accept the pyrosolver type. I have a bunch of h12 setups where I deved my effects and I need to recreate the same look in h12.5 . Any ideas on how to do this? I've been trying to achive the same effect by using substeps but without success. The (one) difference with substeps is that I assume it scales the time before applying forces etc.

Does anyone know why the first input was removed in 12.5?
