distribute rendering problem

[insalubrious]

Hello again I have another question if somebody can help, I'm using distribute rendering for a sequece using phoenix fd and although the plugin is installed on the other machines it doesn't seem to render it,any ideas?

did you change the input path of the simulator? see here for more details.

Ok worked it out, another question is when I use resimulation for foam and splashes do I point to the catch file of th resimulation or the original simulation? Also I have aqustion on rendering the foam and splahes, what option most affects its rendering time?they seem to take forever to render

you mean for dr? to the resimulation. when the resiulation is enabled, the rendering uses not the original path, but the one specified in the resimulation panel.
about the preformance - it seems to be very easy to overload the rendering, we already discussed this question in this thread.
in few words - the foam rendering is very high related to the geometry rendering.
the foam just slows down every ray in the scene (it is an atmosphere), and the first efforts must be directed toward the scene optimization.
of course the foam itself also have settings that may produce significant impact over the performance.
in bubble/cellular/splash mode
- the bounces. the default settings is 1, this is fast, 2 gives better quality, above 2 does not improve the quality but slows down the rendering
in point mode
- the motion blur step. the lower is the step, the bigger is the actual particle count.

in all modes:
- the motion blur
- the image sampler. the foam and splash produce noisy image, this is just in their nature, it's not a bug. the image sampler will produce as many rays as you allow it, there is no enough samples from its point of view. so don't allow it to make too much
samples
- the density (affected by the size multiplier, ior, and the particle grouping). the bigger is the density, the faster is the rendering. thats why sometimes bigger count produces faster rendering, that looks like an paradox

yes for dr Ivaylo, when I have made resimulations and use dr do I point to the resim catch files for the other machines? I followed the thread you pointed me to but kind of got lost. Let me ask some things I'm trying to figure out. What give the liquid it's feel, like I made some simulation that kind of feel like water and others like chocolate, is it just the grid resolution? I will play with the foam parameters you mentioned to see if I have improvements, the water is fast by itself but with foam it's just impossible to render.

can you post an image of this chocolate view?

sorry for the late reply, thanks for the help figured alot out
