super thanks, i was manually going one level up, click the gear > edit parameter interface, add a string channel save it
now "copy channel", and "paste as relative channel" but that to much work have so many channels that i need to promote, is a reason why materialX doesnt have those knobs or right click promote channels?

i am starting to work in a materialX so can be use in the GPU but the materialsX node are well completely different,
how can i promote a channel? usually, you have the little know on the left side, you can right click it,
or you can make a parameter node and connect that one, and magically that Parmeter will be created in the top level under te UI of that node.
i am missing something.

i keep thinking that LOP is a completely different software. like having to prepare an object in maya, export and read it somewhere else.
i have to do my scene in Houdini, and then recreate everything in LOPs. would be great if we can prepare the scene in houdini so in lops context will grab all the stuff we need.
thanks.

i want to be able to add karma properties to a geometry node, before you could go to the spare parms, and from the render tab will be there, but i dont see Karma properties. is there a magic way to add the properties?
https://www.sidefx.com/docs/houdini/props/karma.html [www.sidefx.com]
i want to add
"
Render Curves As:
Houdini render property karma:object:curve_style
"
to just one object
(is there a way to do this with python?)
thanks guys, have a great day.

I haf some materials done in shops but when I use Solaris looks like doesn't like shops. But it shows all the ones from mat context. Is there any difference between the contexts?
Should I use one or the other?

So i can start connecting other nodes like gradients and so on, right now i can click on the node, the param and click promote, but doesn't go anywhere...
should it be inside a material type node?

it seems you need to import the material from the "mat" context to solaris with the import material and then toggle

i am trying to create a new Karma hair under normal shop, under a "material shader builder" should i connect that "karma hair" to an "output collect"?
i did that and now under solaris context(stage) i try to inport that material but i do get warning
"Import of SHOP materials is not supported. Ignored material"
does solaris doesnt like SHOPs?
if i create a materiallibrary and drop a karma_hair and assign it to my geometry now works.
i am missing something and i should think Solaris not integrated with the rest of Houdini?

will be easier to diagnose if you post a hip file. you might need subsamples in the solver, fix the collision geometry, etc...

since this is a procedural creation for mantra not sure will work with redshit. at least the procedural and the shader, but all the tool for creation styling animation dynamics should work fine, and then you can just merge the skin and the curves into other objects and use those to render with Redshift, (sorry i dont have that render)

hey, just uploaded the new version, fixed some of the params that are new in the 18.5 https://polybevel.wixsite.com/fabio-hair-system/download [polybevel.wixsite.com]
with some additional features, hairs as volume, now includes DOPS with vellum, and FEM
i attach and example on how to use FEM, on the hair, just to keep certain hairs in shape instead sim each curve.

hi, haven't play with redshift, don't forget that is a complete different render, not sure if can convert mantra shaders on the fly. or if the procedural hair that is generated by mantra as well.

more important than the percentage, is how many core are you really using
the sim you have might not be hard enough for the power of the cpu.
can also mean the distribution of points to solve is not needing additional compute power, example
if you have 32 core, and you only have 10 points, maybe those 10 points can be solve with just one cpu.

you can install python 3 in the pc,
use houdini python2 to run a python3 as a subprocess,
the python 3 can do the tensorflow and the python2 is just a runner
os.popen.subprocess(“python3 file.py -args….”)
or a vm with linux and put houdini, python, tensorflow etc… all the stuff you need, not something that i think is a great idea since the VM use a lot of Ram, that you might end up needing for houdini process.
this are just quick ideas that came to my mind.

what is the thing you required with python3 that you cant do with python2? if is any library, you can just import it to your python script, beside print() using parenthesis everything else is an internal change, (mostly working range that will become generators instead lists)
when you install python already comes with pip / easy install,

you might be using visualCode as IDE, but the compiler might be pointing to the regular python folder, you might need to change the python interpreter to use the one that comes inside Houdini folder
