“dj white rabbit”-deep house & trance

our studio is located in orange county,ca. we are currently producing w/“reason” and “logic” using apple macintosh exclusively..seeking artists familiar to “touchmixer” software, for the show in s.f. & interviewing dj's & vj's to join us for the trip. also, looking for collaborators for other live events in california and beyond.

Does anyone know where I can download an example scene of “clay sop”?
I have been trying to learn it but it is still a bit vague for me to understand the UV vector deforming idea.

thanks

i get some strange behavior when right-clicking in the viewport with certain operators.
if i r_click on the Handles of a Geometry,the handle menu pops up(as expected),
but as i'm right clicking the Geo itself, it's the same as i'd r_clicking anywhere in the viewport.
(means moving the viewport in view-state or nothing happening in other states)
when i use the mouse evering works as expected.(i get the Geometry menu)

the same happens in Geomode or in the Linearkeyer.
it seems to me that the program can't read out the cursor position when it's over
ceratin opbjects.
has anyone expected similar problems and knows how to solve this?

Hello,



Houdini 8 is ready for download!



Thx

ive figured out a lighting technique which relies on applying a map to a light (at 0,0,0) in order to get specular highlights and and environment reflection taken from chrome spheres shot on a location and converted to longditude/latitude enviro nment maps in HDR shop.. the problem is i dont know where the lights get their orientation from for applying the map.. i want to replicate the orientation of the diffuse mapped lights environment in a shop environment shader so thaat i can use modulation on teh intensity of the map.

does anyone know how to do thisa, or can tell me how the light orients its diuffuse maps.. i`m assuming it is aligned to the world but dont know how to tell vexbuilder reflective/environment map to do the same.

cheers,

Mark

Hello,


does anyone know when the houdini tutorials will be back online?


thx

Now, I'm gonna pass Houdini particles 2 Maya using rf .bin file. Just wondering about attribute mapping things.

velocity -> rfForce(vector) : working
initPosition -> rfMass( vector? ) : maya don't understand.

Is there any other extra variables in .bin(format) can mapping from Houdini.

EX1. I guess, below attributes are vector.(kinda strange)
mass: 0.1/$F*$PT, 1.2/$F*$PT, 0.3/$F*$PT, 1, 1, 1
temperature: 0.5/$T, 0.4/$T, 0.3/$T, 1, 1, 1
force: 0.5/$PT, 0.4/$PT, 0.3/$PT, 1, 1, 1

hi.. i wondered if anyone knows a way to blur and image (texture map) with another texture map in vops.. so that, for example, a black and white texture map could control the sharpness of an environment map.

cheers,
Mark

hi, i was just wondering if theres a shadow bias setting for z depth and fast shadows?
i can do it within a shop shadow shader, but not from a shadow shader aplied within light object.

any help appreciated, cheers,

Hi,
I am a student from the university of braunschweig, germany and I am going to deliver a small lecture on animation systems in about a week. One of the softwares i have to cover is Houdini but I never worked with it before. Now I need something like an overview and a short description of Houdini's special features for animation because it seemes to be impossible to find out everything for myself in that short time.
Points of interest are such things like cloth animation, muscles, fluids, special features for particles and so on. But feel free to point out anything you think is worthwhile mentioning.

thanks in advance

Hi I'm curious about the number of Houdini people per project. Sometimes the interns don't make it to the end credits so I'm sure there are many unaccounted for.

Sony or R&H for example.

Numbers of what precision are used by Mantra at rendering? And whether this precision is constant or it is various at different stages of the rendering process?
The question interests in view of a theoretical opportunity of use of Cell processors for rendering. As is known, SPEs of Cell are able to process numbers with 32bit FP accuracy for 1 tact . And 64bit FP numbers need 7-14 tacts. Whether enough 32bit FP precision for needs of rendering?

I was trying to make a ball spin as it rolled off a table. Got that part. But when I applied the bounce, jello sop from 3D Buzz tutorial, the ball rotated around an axis as it rolled off the table and the bounce also rotated around this mystery axis. How can I apply a bounce to the rolling ball with out the rotation around this mystery axis?

I am a cg student currently learning Houdini and renderman by myself.
I just downloaded a gobo effects rman shader from the following link.

http://www.smartcg.com/tech/cg/books/RfB/download/contents/Ch08_Shading/slideshow.html [smartcg.com]

But it only works properly when I create script files (.rib) in Houdini and then manually type in “ prman xxxx.3.rib” in dos promt. It won't work if I render those sequence directly in Houdini. I mean the projected image would not be seen. Does anyone know why?

Also, can I make this projector shader in Vex builder? I tried it before but whenever I create “illumunate” node, the whole light shader turns black. Can anyone give me a hint?

Hello,

I have a question about TCL and Renderman.

I have a TCL helper application that sends information to Renderman. In order to send the “end of stream” message to Renderman, the TCL has to do a
puts “\377”

The probloem is that this works on Windows but when I get into Linux, I get the following error:
P79011 Undefined binary token 0xc3. (at line 51 in /usr/bin/tclsh /helper.tcl): Context “split gprim”: Object “<unnamed>”
P79011 Undefined binary token 0xbf. (at line 51 in /usr/bin/tclsh /helper.tcl): Context “split gprim”: Object “<unnamed>”

I tried passing the number in two chunks and I got a similar error. I also tried passing it as {“\377”} which did not work either. I have searched through sites and cannot seem to figure out what to do. Any help would be greatly appreciated - it might be something small I'm not thinking about or something large about which I have no clue.

Thank you for the help

I saw this from the mailing list and posting it here just in case anyone is interested. NOTE: I'm not involved in this at all, just reposting.

I am a CG student . I am also learning Houdini.
I tried to use the “layer” sop to create defferent UVlayers. but it does not work when I use rman to render. I tried to put a “parameter” vop and used “uv” or “uv1” “uv2” for the param name in the shading network but it still doesn't work.

Can anyone show me how I can have different UV sets setup for rman?

pls help

I am a CG student. Can houdini generate the shadow maps for rman ‘s point light? Because rman ’s point light needs 6 shadow maps to make the shadow. (+X, -x, +y, -y, +z, -z) Or I have to do it one by one manually?

Thanks
