Hey all,

I've been trying to take a written out pyro sim and slow it down with a gas upres setup. However, I've run into an issue where the retimed simulation seems to lose detail in the flames when rendered. I've attached both a picture that shows the example in my original simulation and then a .hipnc that has a simple example that shows the same behaviour. Has anyone run into this before? And if so, what did you do to fix it? I have a theory that it involves the shape tab on the upres solver lacking some of the parameters that the pyrosolver contains, but I'm not sure how I'd add those parameters to fix it.

People have suggested using a timeshift or timeblend node to work this, but due to the way volumes are calculating, the nodes merely fade in and out from the pre-simmed frames rather than calculating the inter-frames that the gas upres node does.

Thanks for any help!

I am so silly. Ugh.

Thanks so much.

So I recently downloaded Houdini 13, and upon installation I seem to be missing a great deal of my shelves. I have no Particles tab, no RBD, no FLIP, et cetera- all it gives me is Lights/Camera and Fur on startup, although I can add a few other tabs like Animation, Character, Texture, etc. So it seems like I'm just missing the effects tabs. Does anyone have any idea why this is, or how I can download the tabs and install them? If you need any extra information (I know you might not have much to go on from this description), let me know and I'll see if I can get it for you.
