localstarlight Posted August 1, 2017 Share Posted August 1, 2017 I'm using Houdini to render point clouds from depth images, and have everything working for a single frame, but can't get it to evaluate each frame in a sequence. I'm using an expression in the parameter that reads in my image files, so the file path looks like this: D:/UNREAL_WORKING/Brush_VR/Video_Captures/Character_Front/Point_Cloud_Map_01SceneDepthWorldUnits.$F4.exr The $F4 is correctly becoming '0001' on the first frame, but when I slide the timeline around, nothing changes. When I click Expression->Expand String Value, I can see that at each frame it is producing a string that should be reading in the correct file - if I write that same string manually, it pulls in the right file - but it's not actually evaluating the data from the image. What do I need to do to make sure the network is cooked each frame? Quote Link to comment Share on other sites More sharing options...
localstarlight Posted August 1, 2017 Author Share Posted August 1, 2017 Ah, figured it out. I'm using the image sequence in a ColorMap in VOPs, which apparently can't use time-based expressions inside VOPs itself, so I just needed to promote the parameter.
