  1. HI ! We have just started small new studio and we are at the point of choosing proper pipeline for us. we are free from any legacy and are able to build our pipeline from scratch we plan to switch to usd, but not sure what to use - Karma or Arnold. we have experience using both arnold and redshift in the past ....but think about using karma as the best integrated rendering solution (seems like) sidefx says that it is production ready. but does it make sense ? wouldn't we regret ? so maybe someone has already walked this way and could share some opinions ? what is better option to choose ? Thanx in advance fir any info regarding this matter
  2. HOUDINI_ACCESS_METHOD=2 solves this problem only for houdini obviously....but under windows you will definitely have problems in some other cases... for example arnold won't work in batch mode when it is placed on mapped drive ... houdini would not be able to load packed alembics from synology NAS !! xsense can not export animation to drive mapped on synology ! shit ((((
  3. Hi ! I've faced strange problem i'm using Arnold + Houdioni 19.0.657 and everything works fine in Houdini GUI mode ! BUT ! in batch mode arnold just hangs and there is no sign of any activity ! nothing happens ! here is the output from my console : C:\Program Files\Side Effects Software\Houdini 19.0.657\bin>hbatch.exe x:\proj\plo\assets\prop\p_manipulator\look\wip\dltest2.hip 00:00:00 357MB | log started Tue Aug 9 15:39:59 2022 00:00:00 357MB | Arnold [a66d2c1f] windows clang-10.0.1 oiio-2.4.0 osl-1.12.0 vdb-7.1.1 adlsdk- clmhub- rlm-14.1.3 optix-6.6.0 2022/06/23 15:50:29 00:00:00 357MB | running on DESKTOP-TKOPEF8, pid=18832 00:00:00 357MB | 1 x AMD Ryzen 9 5950X 16-Core Processor (16 cores, 32 logical) with 65438MB 00:00:00 357MB | NVIDIA driver version 512.15 (Optix 60802) 00:00:00 357MB | GPU 0: NVIDIA GeForce RTX 3070 @ 1755MHz (compute 8.6) with 8191MB (4682MB available) (NVLink:0) 00:00:00 357MB | Windows 10 (version 10.0, build 19044) 00:00:00 357MB | soft limit for open files changed from 8192 to 2048 00:00:00 357MB | 00:00:00 376MB | [color_manager_ocio] default ocio.config found in X:\hsite\houdini19.0\htoa\htoa-\scripts\bin\../ocio/configs/arnold/config.ocio 00:00:00 376MB | loading plugins from X:\hsite\houdini19.0\htoa\htoa-\scripts\bin\..\plugins ... 00:00:01 376MB | alembic_proc.dll: alembic uses Arnold 00:00:01 376MB | cryptomatte.dll: cryptomatte uses Arnold 00:00:01 376MB | cryptomatte.dll: cryptomatte_filter uses Arnold 00:00:01 376MB | cryptomatte.dll: cryptomatte_manifest_driver uses Arnold 00:00:01 377MB | htoa_mandelbulb_proc.dll: mandelbulb uses Arnold 00:00:01 389MB | usd_proc.dll: usd uses Arnold 00:00:01 390MB | loaded 6 plugins from 4 lib(s) in 0:00.15 00:00:01 395MB | [htoa_op] Begin registration ... 00:00:01 394MB | [obj_procedurals] Registering procedurals ... 00:00:01 394MB | [obj_procedurals] procedural registration done. 00:00:01 410MB | [rop_operators] Registering operators ... 00:00:01 410MB | [rop_operators] operator registration done. 00:00:01 429MB | [vop_shaders] Registering shaders ... 00:00:01 433MB | [vop_shaders] shader registration done. 00:00:01 433MB | [vop_imagers] Registering imagers ... 00:00:01 433MB | [vop_imagers] imager registration done. 00:00:01 433MB | [htoa_op] USD shader translation registration 00:00:01 449MB | [htoa_op] End registration. 00:00:01 449MB | 00:00:01 449MB | releasing resources 00:00:01 429MB | Arnold shutdown hbatch Version 19.0.657 (Compiled on Jun 23 2022) /out/deadline1 -> cd .. /out -> ls arnold1 mantra1 deadline1 /out -> render -V arnold1 Rendering 10 frames ( from 1 to 10 by 1) 15:41:11 arnold1 frame 1 (1 of 10) <----- nothing happens after this string but my PC does not freeze or something like that...i can interrupt hbatch with ctrl+C as it's seen - arnold is loaded correctly...and in Houdini with GUI it renders fine. what may be the problem here ?
  4. Hi i'm using loadItemsFromFile() method lo load data from disk but when the operation is done i appear inside this subnetwork... Are there ways to stay at the top level...(not to dive inside subnetwork )
  5. Uh ... it was my fault . i have not configured proper path to OTLs my render nodes could not connect to otl library - so it obviously could not work it worked only if the asset was unlocked and saved in hip file just like subnetwork
  6. The answer is very obvious : this HDA was not seen by render nodes....fixed. now it works
  7. Hi I'm trying to create asset that submits a scene to HQ and i've faced a problem inside my asset i have a reference from one node to another (see picture) when this asset is unlocked everything goes fine...but when i lock the asset then hq gives error message "ERROR: Cannot find node '/out/wgfarm1/geosave'" in this case
  8. Hi ! We use redshift for render and everything is ok, but We'd like to use some machines without GPU to simulade DOPs or generate geometry in Hqueue The problem is that since these machines don't have GPU, they obviously fail to load redshift dlls and OTLs. Hqueue gets an error and fails to process this hip file. None of redshift OTLs is used or involved in simulation somehow, but hqueue fails anyway just because some unknown operators present in scene. I used to solve this problem in linux by installing some nvidia libs into system, but i can not solve it under windows this way..... And the question is : Are there ways to force hqueue to ignore this type of errors and process hip file any other advices will be appreciated thanx in advance!
  9. wow thanx!!! i've never used this option before....now it's fine...
  10. Uhm ! sorry guys! although it looks ugly in viewport - it renders normal....it seems that it is really only viewport representation i dunno what kind of bug was it on my first render
  11. Hi ! trying to set up a source for smoke sim. i use volume rasterize attributes and get strange results. please see what's happening i have a bunch of points distributed across the space. its bound box is rather big (arounb 80x80x80 units) then i use volume rasterize attributes and get this : as you can see it is very jaggy. of course i've played with pscale or voxelsize/sampling...but i have not managed to get smooth volume then i deleted lot of points and left only one group of them: the same SOP (volume rasterize points) with the same settings gave me different result (nice and smooth volume) and the question is - why i got different results keeping the same settings both for points and "volume rasterize attributes" SOP ? the same pscale and the same voxelsize the only thing that changes is bounding box of my points... and of course it affects the simulation... i also get ugly jagged volume inside DOP.... i can not understand what is wrong....i thought it is just viewport optimization or something like that....but the simulation also goes wrong and i see this voxels in rendered picture as well..... how can i get smooth volume for all of my points ? thanks in advance
  12. Hi ! Firstly i'd like to say that have an experience setting up and working with HQ (render, sim) Now i'm trying to set up PDG working on Hqueue but i've faced some strange issues I've set up everything and try to launch render. it fails output log says: C:/app/houdini/Houdini_18.0.460/python27/python2.7.exe: can't open file 'W:/3DCG/test_rs/proj_td/pdgtemp/21808/scripts/pdgmq.py': [Errno 2] No such file or directory Part of diagnostic information: Client Job Commands: ============================= Windows Command: "C:/app/houdini/Houdini_18.0.460/python27/python2.7.exe" "W:/3DCG/test_rs/proj_td/pdgtemp/21808/scripts/pdgmq.py" --xmlport 0 --relayport 0 --start But....this file (pdgmq.py) does exist and path is correct. even more : if i copy/paste this command line into cmd console - it works. pdgmq.py starts ok. and it's done under the same user as HQclient logs on. I have no idea where to dig further......
  13. Hi ! i'm trying to render particles in redshift. I need to use noise in shader, but the problem is that particles are moving on SOP level and noise also sliding along surface as well In the case of mesh object i just use rest attribute and all is ok. Noise is foxed....but in the case of particles RedShift does not take into account rest attribute on particle.... so it causes noise to move (((( and it seems that we do not have an option to set custom data for noise seed ... it uses only obj position or some vertex data, that particle does not have.... is there any way to get what i need ? to apply bump noise on moving particle and fix it on this particle .... here on picture i have only one particle and it's moving....and bump ((((
  14. SOLVED i've just set up redshift DEMO as a loopback and all necessary CUDA libs now hqueue client loads hip without any errors
