Hi, It seems that generally when animating objects in scene/object level, you are only able to animate variables globally. I have a scene with a spinning propeller, and this spinning propeller needs to rotate around its own axis, while being placed in a certain spot in the scene. How is this achieved? All transforms in the scene are global space, so if you need to rotate the object 30 degrees on the X axis, the Y axis will not follow the local transforms and the propeller will spin sideways in circles. Followup question: I briefly had a teacher from Lost Boys school of VFX and he showed me how to properly load animation data into a dopnet. Unfortunately I was just starting out with Houdini as he showed me, so I did not catch the method. I gathered that this should not be done in sop-level ('Use deforming geometry'), and rather with motion / 'RBD keyframe active' operators in the dopnet -- how do I load in my animation data, so the velocities are correct with proper interpolation? Thank you,
markingleukc posted a topic in EffectsI have 2 sets of points: 'parent' and 'child'. Both have the same number of points. I need each parent point to have a unique child assigned to it - no duplicates. I need to be able to animate in an active value for the parent points, so that they all become active in 3-4 frames. When a parent point becomes 'active', it needs to search for its nearest available animated point and set that animated point's id number as 'child_id'. An animated point is only 'available' if it doesn't already have a parent point, or in other words: if the child_id is currently unused. My issue comes from the VOP I've set up within a SOP solver. If there is more than one parent point becoming active on a single frame, I get multiple parent points assigned with the same child point. I need to be able to write to 'child_id' and read from it on the same frame, to make sure that I am not getting multiple parent points with the same child points (leaving some very lonely, parent-less child points ). Please take a look at my attached file. I've highlighted the important nodes, and the Find Attribute Value VOP in red is where the issue is originating. find_unique_child.hip
Hi, Does anybody know how to submit a "A Simple Parent-Child Example" : http://www.sidefx.co...ationships.html Or how to submit a dependency chain out of Houdini. Like, Simulation --> Meshing --> Rendering. It's simple in Houdini on one machine but how to take it over to Hqueue? Cheers, nap
