duveil Posted November 24, 2015 Share Posted November 24, 2015 Hi , I am a 3D artist usually working on maya and now I am trying to learn Houdini. I have installed aIShaders to maya but when I tried to install for Houdini I couldn`t find in the materials inside shop network. I can see ai default shaders . I have copied dll and mtd files into following folder and I have been searching internet for a while.So I will be greatful if someone point me to a right direction. C:\Users\WS01\htoa\htoa-1.9.0_r1552_houdini-15.0.244.16\htoa-1.9.0_r1552_houdini-15.0.244.16\arnold\plugins This is the default directory that arnold had automatically installed. and here is the env. path # htoa config start PATH = "$PATH;C:/Users/WS01/htoa/htoa-1.9.0_r1552_houdini-15.0.244.16/htoa-1.9.0_r1552_houdini-15.0.244.16/scripts/bin" # htoa config start HOUDINI_PATH = "C:/Users/WS01/htoa/htoa-1.9.0_r1552_houdini-15.0.244.16/htoa-1.9.0_r1552_houdini-15.0.244.16;&" # htoa config end Thanks in advance and I am sorry beforehand if this is a newbie question.

dennis.albus Posted November 25, 2015 Share Posted November 25, 2015 You have to set the ARNOLD_PLUGIN_PATH to the path where your additional shaders are located. [path]/[to]/alShaders/bin Be aware that you won't see them in the SHOP context directly. They will only be picked up by Arnold inside a Arnold Shader Network.

I was searching aIshaders inside material list and as you said it is inside Arnold Shader Network.Thanks a lot for your time.I owe you one.

R_cyph Posted August 28, 2016 Share Posted August 28, 2016 (edited) I can't seem to get alshaders installed for either H15.0244.16 or H15.5.523. I've tried copying the contents of "..alshader/bin/*" directly to the "..arnold/plugins/" folder or setting the ARNOLD_PLUGIN_PATH = "C:/Users/SR2/Downloads/alshader17/bin" in my houdini.env . Yes, I've looked for the nodes in the Arnold shop network as well. Any ideas what could be stopping the shaders from getting loaded? Does a specific version of alshders only work with a particular arnold version? Arnold seems to be working just fine as well. I'm on a fresh format/install of win 10 pro.

dennis.albus Posted August 29, 2016 Share Posted August 29, 2016 While Arnold is not particularly picky about this, there are certain combinations that don't work well together. Ideally you have an HtoA version for the specific Houdini version as well as alShaders compiled for exactly the same Arnold Core version as HtoA. Could you launch Houdini from the commandline tools and copy the Arnold log in here? If the env is set correctly Arnold will tell you that it tries to load the plugins from the alShaders location. If something goes wrong (like non compatible versions) it will load 0 (zero) plugins and also print that to the log. Cheers, Dennis Quote Link to comment Share on other sites More sharing options...
Juraj Posted August 29, 2016 Share Posted August 29, 2016 Hi, can you see any errors / warning in Houdini console when rendering with Arnold? Quote Link to comment Share on other sites More sharing options...
R_cyph Posted August 29, 2016 Share Posted August 29, 2016 Here is the logs. It says it can't find the plugins. Yet I've tried loading from 2 different versions of the alshaders ( ORC17, and ORC14 ) from 2 different drives and it just refuses to load them. The file paths are local and valid. I'm truly stumped. the 2nd log is from the ../alshader/bin copied directly to Arnold plugins folder. In both cases it gives the same error which makes little sense. The silly thing I can install it just fine on my laptop...

dennis.albus Posted August 29, 2016 Share Posted August 29, 2016 There's a mismatch between the Arnold version (4.2.11.2) and the version that alShaders have been compiled with (4.2.12.2). Try and install the matching HtoA version and see if that fixes your problem. Quote Link to comment Share on other sites More sharing options...
