you can do it with Statick_Object(DOP) only. it seems to other settings are no problem for volume collision. flip_bowl@3.hip

Better way, ignore folders , files only "isfile" import os thePath = 'C:/myGeo/' fileList = os.listdir(thePath) isFileList = [] for f in fileList: if os.path.isfile(os.path.join(thePath, f)): isFileList.append(f) fName = (thePath + max(isFileList)) #print fName return fName

resolved 0)files example > 'C:/myGeo/myGeo_v001.begeo.sc','C:/myGeo/myGeo_v002.begeo.sc' 1)set default Language = Python 2)Ctrl+E fot multi line script on the parameter slot import os thePath = 'C:/myGeo/' fileList = os.listdir(thePath) return thePath + max(fileList) return 'C:/myGeo/myGeo_v002.begeo.sc' thanks

hi, very basic question i have, I want get most newest version file for "Load_Layer(LOP):File parameter" example in python import glob import re import os max(glob.glob('C:/USD/myUSD_v*.usda')) return>'C:/USD/myUSD_v003.usda' this code running in python, but not running in Houdini. this code does not include Houdini objects. how to write the code in this case? thanks

avoiding this ploblem with below technique. adding Huge Dome(or Sphere) for Matting.(hope infinit geometry...) And RenderGeoSettings(Arnold/visibility) is CamerarayVis=On, Matte=On, others Off. no shader. domelight HDRI Alpha has bugs? please tell me any if you know. thanks

hi, in solaris with Arnold, domelight fills alpha channel full. HDRI use or no use, it's no relation, always fill alpha. i heard, Mantra has the option hide light-geo. if you know please tell me,in solaris, how to hide domelight in aplha channel? if can do it , show rgb the environment color, only off alpha for tranparecy area. thanks

that's great! "Set a keyframe", really need. thanks

hi, simple python script sample 'a_b_c'.split('_')[0] >'a' samely, i want to execute python script as parameter value, example) hip filename is "s001_c001_myScene_v001.001.hip" $HIPNAME.split('_')[0] but it's retuen same strings, very confuse. i want get "s001" in this case. please tell me how to write them? thanks

so bad. last resort example, switch streams "shaderball-stream" temporary. i hope more advanced shader preview in houdini.

hi, cannot prune Geosubset. simple example file atached. i want to careate some variant, the option is removing some Prims by prune GeoSubset. what's wrong my operation? thanks solaris_sahderWork_v001.001.hip

hi, "Resample by Polygon Edge" option, keep same position. hope helpful velocity_resample_v001.hipnc

on materialPalette and /Mat context, can i get shaderball preview the materials? only way on /mat, RMB>Update_ShaderBall_Icon ? it's not modern style.very slow, /mat has no texturemap previews. 3dsmax has standard style today mateiarl editor.(on-the-fly update, back-light, checker-environment, etc.) other parts, houdini is most future style good!

Librarian By the way, the first example was to make a curve follow a ray. It doesn't work well on curves. An alternative might be to match the curve to the polygon deformation. For example, Lattice Deformation But anyway, I'm glad that Soft Selection has become easier. FallOff_SoftSelectionCurveRAY_v001.001.hipnc

Ofcourse, this solution works also on RAY(SOP). distanceAlongGeometry(Falloff) is similar "soft-selection" in 3dsMax, so procedural for any. FallOff_SoftSelectionRAY_v001.001OD.hipnc

I'm sorry so late. i had found very nice tutorial about soft-selection. "HOUDINI FOR THE ARTIST: WORKING WITH THE FALLOFF NODE" https://lesterbanks.com/2018/11/houdini-new-falloff-node/ H.17 falloff(SOP), but in H.18, it's distanceAlongGeometry(SOP). distanceAlongGeometry(SOP) output "dist" atrribute. showing H.18 version.
