Hi there
Not sure whether about the shader you have there and Houdini.
But this one works https://github.com/groundflyer/physhader-for-mantra [github.com]
And there is a nested dielectric shader in Houdini 16.
cheers
Nigel.

Hi There
I was wanting to test/use the new nested dielectric capability of the principled shader on a project I've been working on with 15.5.
I can open it in 16 if I turn update to manual but I update to display the scene it crashes and I get a segmentation fault.
Is there anything I can do or is this to be expected?
thanks
Nigel.

Hi there
Does anyone know if I can upgrade from 15.5 to 16 and still use the same hip file?
Won't need to re run the sim, I just need to bring the geo in and render.
I was using the Physhader for a pbr glass material and it's nested shader etc. It was really nice but I can't at this stage use it on Gridmarket.
They say they will address the issue but it won't be today ish.
So I'm considering upgrading to 16 indie and having a look at the new glass shader.
If I download 16 indie, can I still keep 15.5 indie in case this hip and others have issues with 16 indie?
Any advice much appreciated.
thanks
Nigel.

I'll post if/when it get resolves.
I had similar issue with blender and a meshing plugin I was using with the Renderstreet farm, that was eventually resolved and the issue apparently was the plugin needed to be installed in the correct place their end in order for it to propagate across the nodes. Hopefully this is something similar.
Tho I guess if that's the case it still means any external custom code needs to be installed at their end rather than simply being uploaded at preflight stage.
Not that I know much about this at all.
So now I need a Pbr Glass shader but I'm running 15.5, do I take the punt and switch to 16 and trial the new glass shader hoping my hip file will work… questions questions and the day is short.

Hi BabaJ
Thanks,yeah I managed to figure that out. The preflight was looking for links in disabled nodes, once I cleared those out it was fine. And yeah I should stick to relative path references..
However I still have a problem with that hip file and gridmarket as I was using the Physhader and that isn't working, I thought I could just upload the hda but that doesn't work. Gridmarket are currently looking into it but are to busy today to resolve it here and now.
Thanks very much for your detailed description, appreciated.
cheers

Actually sorry, what do you mean by "Then you can put in the Environment variable that your hip file uses to refer to the ‘external’ file.
Excuse my ignorance.

I tried adding in the render folder for download and that works ok but I need to get rid of the stuff in red as it errors out in console and won't continue.
I've given support a yell so hopefully they get back to me soon ish. Frustrating, but my own fault I guess I should know about the structure of the file setup..
Thanks.

Hi There
I hope someone can help because I have no idea what I've done wrong.
When I look at the preflight window I have a whole lot of red folders and files as per the attached screen grab.
I'm guessing my environment are wrong or something?
The way I have it set up (or not) on windows 10 is Houdini program files are in the c
program files..
My Hip file is on d
If I read setenv from textport with the hip open $HIP = d:
Any help much appreciated.
thanks
Nigel.

Hi There
I had a look at the hip you posted on odforce, I think it's your friction and bounce variables on the col vol for the caramel.
cheers

Hi There
If you mean you're getting less fluid at lower p.s values, yep that happens as it settles, you can increase the initial volume to compensate and or mess with reseeding.
To get more detail you can play with the droplet parameters.
Also maybe add some random velocity into your fluid.
And finally look at it thru camera, the scale of the shot is important when it comes to judging the level of detail you're achieving.
Here's a link to some Flip tests from Igor Zanic who is a genius with this stuff. https://vimeo.com/86802065 [vimeo.com]

flip fluid emitter won't work once it's covered by an existing flip fluid.
there's a tutorial in the tutorial section that runs thru how to fill letters with a flip fluid, that might be useful.

Hi there
It's a bit hard to understand what you're doing without seeing a hip file but if you are trying to emit particles into a tank of flip fluid via an emitter already covered by flip fluid that won't work. An emitter needs free space to emit into - a non technical description, sure there's a better way to explain that..
cheers

Could you keyframe the reseeding variables to add more particles within a given time range?

I've seen it when using a particle emitter, it was related to the shape of the emitter, not sure if this is the case here tho.

Thanks Artye.
So it may be worth digging into the flip solver, hunting for open cl check boxes, setting to on and seeing what happens?
cheers

Hi again
Actually if I turn off the pop forces I still don't see any activity on the gpu?
I've got a particle separation of 0.005 and I'm using viscosity so I was hoping I could use the gpu?
thanks
Nigel.

Hi
Just a question re Houdini and open cl on a gtx 1080 when using the flip solver.
So from what I understand if I click the use the open cl check box in the solver the flip solver will use the gpu if it's recognised by Houdini.
If I look in the about Houdini window it's listed there but I don't see any activity pushed toward the gpu and no significant increase in performance.
Is this because I'm using pop forces in dops?
I think Jeff Wagner mentioned something about this in todays flip webinar but it was 4.00am in the morning here so I may have misheard that?
thanks
Nigel.
