localstarlight 8 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? Share this post Link to post Share on other sites
localstarlight 8 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.
