  1. Problem Solved. Problem was in expression. point("../node", 0, '"attr", 0) doesnt support for string attributes. Instead of this I've used points() expression function. I've incerted this expression in the FILE_SOP textfield >>> `poins("../node", 0, "path_attr")` Now I able to load the pieces I needed and load any attribute for corresponding piece of geoometry with Attribfrommap SOP. I cant upload work project here, but I try to prepare and upload scene here a bit later. Thank you
  2. I've got it. Looks like Instance SOP really doesn't needed for ForEach. Watching attached scene, Dived inside Instance SOP I still have a problem with a string attributes or stamping attributes in TextField. Same story but another attribute @map_path. I need to read attributes loaded from Attribfrommap SOP for each piece of geometry wich corresponds to certain point
  3. Thank you, Anim! I'm Using ForEach for an array of points to load a geometry to a scene. This really works )) Now I'll try to make some scatter on this ))
  4. Hi guys. I have an array of points with an attribute @mesh_path and @map_path @mesh_path = "/mnt/projects/model/mesh.001.proxy.OBJ" and File SOP connected below I can't read file if I use attribute in a FILE_SOP text Field. `@mesh_path` Is there any possibility to use string variable in FILE SOP text field to read the file?

  7. Then I used ForEach SOP for stamping random instanses from MergeSOP onto points. But still looking for solution with node connections. If some one has an idea, pls.
  8. Not that I really wanted but I made this in a bit casual way. I've merged all objects which I needed for copystamping with "instance.*" , cheked "PackGeometryPrimitives BeforeMerging" and count points number with npoints("../out1"). Now I've got number of objects for copystamping. WIP
  9. Hi guys. I want to create an asset for copystamping which will allow to connect or disconnect SOP inputs. Would be nice if asset allow to use different input numbers of instance at a time (connect/disconnect necessary objects) and switch between instances. I can manually create a CopyStamping asset if I have a static number of inputs and if I know a number of input objects which switch operator will use (basic copystamping technic). I've dug out some info and looks like it's best way to create the asset with a callback scripts. But I'm not familiar with callback scripts and python enough. May be some body can help me with that or have a links for similar solution. Thank you.
  10. Hi guys, I'm still trying to resolve problem with transferring houdini points to maya. I found houdini engine quite helpfull with that, it works fine with copy stamping, but I'm trying to use Arnold INSTANCEs (standins) because point number is to large and maya crushes if i use geometry. Arnold Instances work fine on point in houdini but houdini engine doesn't transfer any arnold parameters (asset provide all houdinis tabs exept Arnold tab). I think this happens because Arnold operators aren't native houduni operators and standins in maya doesn't have a shape node. Is there some way to use engine with arnold instances?

    I think you can add Normal to your spline. May be this will be helpfull. Then you may add additional transformation with Transform operator and stamp expression function. CopyStamping available in houdini help. ps must be something interesting in IvyGrowingArchy )) but my houdini load scene with errors (( Ivy.hip
  12. It works ^_____^ Hm. I haven't foud information about this in manual at all >__>
  13. I've visitet https://www.solidangle.com/arnold/arnold-for-houdini/ There is the picture below in Gallery with instances. Looks like Arnold should render instances.
  14. Ok. Particle rotation works with velocity, because particles has velocity attribute. Braking head on point rotation/orientation. I've got some rotation (im maya) exept rotation along Y axis. I used point sop to set up velocity as $NX/$N/$NZ but I cant get rotation along local Y in maya because velocity is in't quaternion? >__> So I still have a point orientation problem ((
