How to cache standard explosion from browser?
You can use it like this:
Note two things:
- The file cache is before assign-material. That keeps assign material live whether it's set to read or write. This material is a "material scene reference", which means the material does not exist in the Bifrost graph but is in the Maya scene, so the bob file written to disk will not contain the material.
- We're using the "first object" output. That's because what's coming in is a single value, not an array. You can tell what is an array by looking at the graph by looking at the shapes of the ports - hats are arrays. http://help.autodesk.com/view/BIFROST/ENU/?guid=Bifrost_Common_build_a_graph_port_types_html
On point 2, that's why file_cache has two outputs. It had to be array in for reasons I won't get into that have to do with interaction with auto-looping, so it has two outputs depending on how it's used.
Ah, thanks Jonah. I had tried that, but I realize now that I actually forgot to set the file_cache to write mode after applying there and was thus getting only the undulating source geometry coming through. Could I suggest that you produce some kind of null response if the file_cache node is set to Read and there's nothing to read? It's confusing getting some kind of output result; if I'd got nothing or an error I think I would have more quickly realized my stupidity and set it to write.
Also, while on the topic of this particular explosion preset, what's the quickest way to increase the resolution on this sim to eliminate the striations (I'm assuming the result of coarse voxel size)?
Should we adjust fluid detail size?
What would be really helpful is a tutorial video specifically focused on design time and render workflow: best practices for dialing back a simulation during design time while keeping the overall shape predictive of the final high-quality render.
