Lagoa_Density not cacheable
Hey list, i can't read the Lagoa_Density attribute from my cache files, giving me this error msg: The cache has a different definition for attribute 'Lagoa_Density'. Loading canceled This is a massive showstopper right now, i have should check that. I thought this attribute is a value per point. I could try to write this attribute into a custom attribute, but this is a heavy simulation, i don't want (and don't have the time) to re-sim. any hints how i could fix that would be much appreciated. sebastian
Re: Lagoa_Density not cacheable
ok, nevermind. as soon I've send this mail, it worked. this attribute was set per object at first. and ice didn't switched the context. piped in an execute node in-between and somehow this one was refreshed properly. i hate to get all apocalyptic before my first morning coffee. . .

Re: Lagoa_Density not cacheable
Hi Sebastian, if it is just a color gradient by particle density that you are after then it is really simple to get this with a Get Neghbours count rescale range gradient ie this https://vimeo.com/1618403 it is a fast realtime calculation (as long as you set the search distance to a reasonable level!) than can be applied in the modelling stack of an ice tree to an already cached simulation affecting the color if its something else required from the actual part of the Lagoa Simulation then I have no idea of how to get it without simmming again.

Re: Lagoa_Density not cacheable
Sometimes when that happens (the definition mismatch thing), you just need to reload the scene and it sorts itself out.

Re: Lagoa_Density not cacheable
jep, had that idea after thinking more about it (and drinking my first coffee). but I've shivered a bit by guessing how long this would take on a 10 mill + cloud ;) thanks Am 23.11.2012 um 10:37 schrieb Rob Chapman tekano@gmail.com: Hi Sebastian, if it is just a color gradient by particle density that you are after then it is really simple to get this with a Get Neghbours count rescale range gradient ie this https://vimeo.com/1618403 it is a fast realtime calculation (as long as you set the search distance to a reasonable level!) than can be applied in the modelling stack of an ice tree to an already cached simulation affecting the color if its something else required from the actual part of the Lagoa Simulation then I have no idea of how to get it without simmming again.

Re: Lagoa_Density not cacheable
...happens everytime to me. What I always do is to init the custom variable on the right context *before* loading the cache (cahe on file node). It prevents the rest of the icetree from screwing up with your attribute. 2012/11/23 Sebastian Kowalski l...@sekow.com jep, had that idea after thinking more about it (and drinking my first coffee). but I've shivered a bit by guessing how long this would take on a 10 mill + cloud ;) thanks Am 23.11.2012 um 10:37 schrieb Rob Chapman tekano@gmail.com: Hi Sebastian, if it is just a color gradient by particle density that you are after then it is really simple to get this with a Get Neghbours count rescale range gradient ie this https://vimeo.com/1618403 it is a fast realtime calculation (as long as you set the search distance to a reasonable level!) than can be applied in the modelling stack of an ice tree to an already cached simulation affecting the color if its something else required from the actual part of the Lagoa Simulation then I have no idea of how to get it without simmming again.

Re: Lagoa_Density not cacheable
I mean, sometimes you cache it in the right context but ice refuses to read it...that's my case above. 2012/11/23 Fabricio Chamon xsiml...@gmail.com ...happens everytime to me.
