non-hardened environment variables in IFDs? 7 years, 12 months

Darran Edmundson

Is it possible for Houdini to *not* expand environment variables when writing to IFD? More generally, what options are there for dealing with relative paths when moving from one's local machine over to a render node? For a given project, I tend to create a directory tree with one or more .hip files in the root folder. Resources are then referenced as $HIP/shaders, $HIP/maps, etc. In the ROP, I'll then prepend my output filenames with $HIP/render/diff, $HIP/render/spec, etc. This works great on the local machine. However, writing to .ifd, the $HIP (or any other environment variable) gets expanded. My hack is to run a post-render script that does a search/replace of the hardened strings, converting them back to envvars. Of course this only works with ascii IFD. I'd be very interested in hearing how others deal with path issues ... Cheers, Darran. P.S. I've got a nagging suspicion that I asked a similar question on the list last year. Can't find a reference to it in the archives though. -- Darran Edmundson [darran at edmstudio.com] http://www.edmstudio.com

Feather/Fur for Bird 8 years, 7 months

Diana Li

Hi, I am working on a project involves feathers on a bird like creature. I need some help to see what's the best approach. The creature will fly, but only in medium shots and long shots, and there is one close up shot of the head. I haven't found any tutorial on fur/feather system. After researching, it seems that to create feather, it's adding fur on a tube like geometry, then copy/instance it to where you need it. Does that sound right? I never used fur, I'd really appreciate it if someone could point me in the right direction. thanks. diana

chops and docs 8 years, 7 months

baq

there are many parts in houdini's docs about: particles, dynamics, animation, lighting, etc, but I don't see anything like this about chops, yes there are channel nodes description and that's all, all other parts have more attention so one can know how to start to work with but not with chops, some advnaced users say chops are so cool, powerfull, etc, etc but yeahh just try to start with it when you just have nodes description and don't see the whole concept, also tutorials I've found talk about chops+audio, I don't care about audio, I know many use it for motion, remember article also when DD said it was used by them in grinch ... do you hear me sesi SESI or anybody

Reloading pop groups 8 years, 7 months

robert east

Hi List, I have currently hit a brick wall with getting pops to work in a grouping context within a voppop where they leave and join other groups driven by a ramp. It has been suggested that there is a technique to empty all groups on each step and reload them. Does anyone happen to have an example of this technique or a possible workflow ?

wire object and spring constraint 8 years, 7 months

Martin Matzeder

Hi, I'm trying to recreate a effect I did long time ago in h8 with wires in dops. I created a wire that was springconstrained to a goal wire, but the strength of the spring was controled on a per point basis. in sop i could set the strength of the spring constraint per point. If I remember right , I used the wireglue constraint and edited the copydata sop inside the wireglue to add the necessary strenght per point stuff. But imagine this, I can not recreate this in h10 :(. so my really burning question is how to set this constraint system up in h10. and more information on the copydataDOP would help here to. thanks a lot Martin
