UPDATE:
So, fresh from Juanjo at Redshift…
“Are you trying to instance proxies from the RS Proxy SOP using the copy SOP? This is not going to work at all. The Proxy SOP is there only to preview the proxy in the viewports, but it can’t be used at the SOP level to copy the proxy or things like that. The best workflow to copy/instance proxies is to use the “instancefile” point attribute.”

Hi Gang,
I'm wondering if it's possible to use copy to points with redshift proxies? For scattering trees over a piece of geometry. The proxy itself renders fine but when i object_merge it into another network with copy to points all i get is the bounding box. I've no idea what the workflow should be…
cheers,
Andi.

Not entirely surprising but i assumed that all those nodes that start with “GAS” might have something to do with gas in a fluid sense which informs what i think they might be used for…. Am i right? or does it stand for something entirely different? General attribute solver? something like that?

Sadly this isn't what I (we) were hoping for.
The request is for a camera rig with a physical interest null that works with the view tools
The behaviour would be:
That the camera always orbits around the interest null.
When using the view track/pan tool the interest null gets translated the same as the camera so the camera rotation remains the same.
When using spacebar+f to frame an object the interest null gets moved to the centre of the object you are framing up.
cheers,
Andi.

Hi,
As an indie user how can I check the status of bugs that I haven't logged? For example someone else logged #87569 on my behalf.

Hi Guillaume,
I was wondering if this was slated to get fixed at all? I'm still getting the same behaviour in 17.0.352

Cheers Werner, I was unaware of the MMB which works well enough for the time being. Viewport work definitely needs a bit of love in Houdini.

Hi,
I need to transform something by a small amount and would like to use the manipulators to do it, but the pivot position is a long way off. In old softimage land it wasn't a problem as you could transform stuff without having manips visible. Is there a quick way to do this in Houdini, working in the viewport and not using the ladders? Even a “move pivot to bounding object / vertex average” type thing would work so long as it's at sop level.
cheers,

Hi Artur,
well my massive chute certainly won't be helping, cheers for that. Do you have a clear idea of what the scale issue was doing? I've always done fluids in realflow as sph sims so flip fluids are new to me really. Could it be something to do with the voxel size of the fluid versus the thickness of collision obstacle? Can I do some sort of visualise on the voxel grid to check that?

The time has come to churn out something for real rather than endless tutorials and suprise surprise it's some fluid! Except my fluid is vanising… I've fallen at the first hedge as they say.
Collision geometry is really high res but the points just vanish. Point count goes down by half over a couple of hundred frames. If anyone can give me a pointer beyond “make your collision geometry thicker” i would be stoked…. I've attached the hip file and the .obj the the scene reads. Just knowing what's killing the points are going would be a start other wise it's back to the other fluid simulation solution which is a bit counter productive!

I'm having to move my camera and aim null in a front/side/top view to get the camera to do what I want. The default setup of having to rotate the camera to get it to point at an object is a pain especially if your camera is moving all over the place and the object you're interested is also moving around. If I don't set up an aim null then my perspective camera will orbit around some arbitrary point in space rather than a specific point in space. Being able to lock down a point in space that the camera is looking at AND move the camera around with the ease of view tools is what I and i think Julca are after.

Hi,
thanks to this thread https://www.sidefx.com/forum/topic/16761/ [www.sidefx.com] I managed to get command line rendering working using a.csh file that looks like this:
#!C
PROGRA~1/SIDEEF~1/HOUDIN~1.323/bin/csh.exe -f
hrender -e -f 1 25 -v -d /out/mantra1 SPROJECTS/myhipfile.hiplc
hrender -e -f 25 50 -v -d /out/mantra1 SPROJECTS/myhipfile.hiplc
hrender -e -f 50 75 -v -d /out/mantra1 SPROJECTS/myhipfile.hiplc
only problem is they all render at once! Any idea how to get them to run sequentially please?
cheers,

Hi,
does anyone know if there are differences between these 3 types of rendering? Are things unavailable in the render region/render view? For now i'm only talking about Mantra

Having slept on it and also compared the two I actually think it comes down to object preselection highlighting, I just don't like it as I find it distracting, the lack of usefull selected primitive highlighting in wireframe mode, it just looks like an edge select to me. The more i dig and direct compare the less I can put my finger on so it's good that you posed the question. I don't want Houdini to turn into soft at all but one thing soft has over every other package is workflow harmony which to someone involved in art can only be a good thing. I may well have made a fuss about (almost) nothing here so apologies if i have…

Hi Twod,
that's certainly allowed me to crack on, very helpful. I do find the selection in Houdini tricky compared to soft, I know there's muscle memory involved but there might always be better ways to do things. I guess if the bulk of core users don't want things to change then it makes positive evolution of a product tricky.
