Hi everyone, Kind of a simple question but can't quite figure it out. I scattered some points and copied cubes on them, randomized attributes including pscale I am getting a nice exponential falloff on pscale which is what I want, but its in reverse. I want it to start big at the bottom and gradually taper off to nothing at the top. Basically the exact opposite of what Im getting now (see screenshot). Any idea how I reverse the direction the exponential falloff is happening? Thanks! Matrix_Panel_Updated.hiplc
The gist of the effect I need done is this. I need this Logo to start out fractured into a ton of pieces and off screen in all directions then I need the pieces to kindof suction in towards the screen center where they come together to form the full logo My current workflow is basically run the sim backwards (the logo starts off fully formed and i explode it outwards, then reverse the RBD sim) The problem when I reverse the sim I get a very harsh stop on each piece once the piece gets to its start pose I fix this sort of by running a jiggle or lag CHOP motion effect over the points after i reverse the sim, adding some overshoot to the sim so it overshoots the rest pose and then settles back into the rest pose the issue is now i get intersections with the pieces. Was hoping someone might know how i could maybe run another simulation on top of the reversed sim? Like have it follow the same motion but adjust for self collisions?
olivetty posted a topic in General Houdini QuestionsHello all! I have this problem where my sweep is being flipped on random frames. It seems the points on my animated curve are jumping around in the spreadsheet (but not visibly). The curve is generated from a A-BSeam group from a boolean of a cylinder and a big noised-up box that goes through it. This is then resampled to get a constant pointcount. I'm resampling on every frame so this is the problem I think. The curve then travels upwards. I generate an up-vector with a simple wrangle @up = set(0,1,0); and then feed it into a sweep. The sweep looks fine and works well but on certain frames the whole thing flips and the sweep flickers. I've made a video to show the problem that you can see here: https://drive.google.com/file/d/13Ch6K2lNKK5diDRQggiNkFwXTKsC3GCP/view?usp=sharing Here is the HIP-file: https://drive.google.com/file/d/1M1WPRLivDL4PzK9v_1I99UOruoVweCVG/view?usp=sharing
LaidlawFX posted a topic in ScriptingHello, I'm using Hscript for some paths in Houdini and some of the global variables on windows are coming in as Backslashes \ and for some uses I need them as Forwardslashes / in Houdini and \ backslashes outside of Houdini. Is there a way to change the forward slash to a back slash? Unfortunately backslash is an escape character... http://www.sidefx.com/docs/houdini13.0/commands/_guide#idm47064707811440 Example C:\Windows needs to be C:/Windows As silly as this is in order to convert the other way this is the method i have, but doesn't work in the reverse `strreplace(strreplace("C:\Windows","/","\ ")," ","")` Thanks -Ben Edit: mistyped forward instead of back
