solaris USD Python API in Solaris
reyan posted a topic in General Houdini QuestionsHello wizards, i'm trying to get the camera from the current stage and then get the frustum I'm following the Pixar API, but probably i'm missing something... Here my code: from pxr import Usd, UsdGeom, Sdf node = hou.pwd() stage = node.editableStage() # Add code to modify the stage. # Use drop down menu to select examples. camera=stage.GetPrimAtPath('/cameras/camera1') gfCam = UsdGeom.Camera(camera).GetCamera(1.0) frustum = gfCam.GetFrustum() Problem: GetFrustum() gave me an error, it seems that is not a method of the camera class, but it should... Any idea ?

editmaterial - how to?
marcosimonvfx posted a topic in Lighting & RenderingThis might be a super basic question, but for the life of me I cannot get an editmaterial node to work with Karma nodes (for redshift it works): Redshift: In a materiallibrary I create a rsMaterialBuilder and inside I create my node network, flowing into a redshift_usd_material node at the end. Then when I create an editmaterial node and load this material I get the complete tree of nodes to modify. With Karma this seems different. First I don't need to create a materialbuilder, I can create a principled shader for example right there (though I have also tried with a materialbuilder). I create my network with for example a texture (and I have tried with and without a collect node at the end) and after want to modify this in an editmaterial node. But if I do that the network inside is always broken and none of the additional nodes (texture) is there (see picture)? Has this ever happened to you? What am I doing wrong?
Houdini 18 karma GeoLight / volumeLight Issue
luc255 posted a topic in Lighting & RenderingHey, I was wondering if I was the only one having this issue with Karma on H18 : I can't use geoLight or emissive Volume to light an other object. Any idea ? Maybe it's still impossible on the early beta version.. Sylbert. PS : I haven't find a way to setup the amount of ray limit in Karma setting as well..
