Hi

i see some error messages in the console when starting recent builds, the last working one, I had installed is 10.0.465, newer ones seem to have problems with some directories. I'm running windows 7 ultimate

the error looks like this:

Could not initialize help system: error: Zugriff verweigert: ‘c:\\users\\admin/*.*’
exception: WindowsError

does anybody else experience this?

Indeed, I even did't have time to log a bug. Great!

I encounter some inconsistent quaternions during animation of captured geometry. I made a little test setup to demonstrate the problem.

in the main take both bones rotate, and that's where the problem occurs. the 2 other takes have only on bone's animation active.

I added a object to visualize the orient attribute on the geometry, and as You can see it is inconsistent during the animation.

how can I avoid this strange geometry jumps?

best regards
Martin

You must set the alpha of Your matte material to zero

the mantra rop has a command line in it's parameters, mantra allready is there , just add You stuff their

ok, the problem is that some node's keyframes do not show up in the timeline, like the rbdactive, but I added a 2 hotkeys, now when i hover over a parameter i can jump to here. thats fine

you mean the copyDataDOP? I'm sure there are more than one way to achieve it, as usual, hehe

Hi

when I remember right there were two arrow buttons in h8 in the parameter pane to quickly jump to the previous or next keyframe. is there a way in h10 to get them. I could not find it.

Martin

mh, not sure about the argc expression, but maybe I didn't get your idea
i was thinking about linking them by a additional data in dops, we will see.

Martin

hi,

in Your mantraROP, check out the output tab under properties. there You can add additional output planes and N is a standard output. if You render in exr You should be able to use it in nuke

Martin

hi Manuel

modify your dopfield expression in the rbdstate node to:

if( dopoption(“.”, “grid”, “Position”, “ty”) >= point(“/obj/dopnet:mygroup_”+($OBJID-3)+“/Geometry”, 0, “ymin”, 0), 1, 0)

Your box naming starts at zero, but the objid is allready at 3, as 0,1 and 2 are allready occupied by other objects.

I'm also looking for a way to reference this more bulletproof


cheers Martin

haha, great peter, keep going

hi manuel,

opinput returns a string, no need to convert it, by putting the function in “” I think You turn this in to a string and not the result

Martin

switch both uv_front nodes to vertices instead of points

cheers
Martin

sometimes it is a good idea to scatter points, and use them as source, so You have exact control.

EDIT: ha, missed Your last edit :roll:

thanks, sounds very interesting. My only fear is that it is as addictive as houdini.

touchdesigner, what exactly is it and what role does it play in concerning houdini? I'm just curious.

Martin

hi manuel,

if You use N to orient Your copies, they are only restricted to one axis, but they still have the freedom to rotate 360 degrees around this axis. not defining a upvector is unsafe. by adding a upvector You get them locked to a specific orientation. iksystems also use a upvector, for example

Martin

The second part is online now. It's about the metaball Loop

Hope it helps

Hi,

I did a little summary for volumeshading in houdini using metaballs. The first part is done. May be it helps.
