  1. Since you are a bit new to rangemappers (and possibly XPresso), maybe I should point out how % works in C4D (you have probably sussed this out already, but might help someone else). If you have RM input and output ranges set to 0 - 100%, and input say 50% from a slider or other node, then hang a result node on the output it shows 0.5 not 50. This because XPresso treats % as a decimal 0 >> 1. It confuses some people the first time it happens - double checking your math etc. A similar thing with degrees - if both RM ranges are set to 0 - 360 deg, and you input 30 deg, a result node on the output shows 0.524 because XPresso uses radians (2 * pi radians = 360 deg, 1 rad about 57 deg). For these reasons, I prefer to just use decimals and radians for my XPresso stuff then I know exactly what's what. A lot of C4D users think they have to use the degree node to (unnecessarily) convert degs + rads back and forth when using XPresso for wheel rotation calculations etc. There's no need - when you use degrees (or %) in the GUI, XPresso just converts them anyway.
  2. Are you saying the rangemapper is calculating outside the range - have you got clamp checked ?
  3. re: hinges - I know zilch about soft bodies, so you are probably correct.
  4. You could try pulling the boat with a spring on a spline, that way it can still react to the waves but goes where you want. Here I've put a 2nd spring aft to keep the boat straight, 2nd spring position set in xpresso a certain % lag. Not sure why the sea has hinges - I made it a collider. You could maybe link the other boats with springs ? Some ideas for you anyway.
  5. I see why you used 2D now. In fact I'd never noticed that 2D vector option in user data - so I learned something today as well.
  6. Your file has a heap of stuff I don't seem to have. This is how I'd do random speed on a spline, using noise - it's smoother than random numbers that jump all over the place every frame.
  7. Not sure why you are using 2D, but here's a 1D file. I think you are getting invert and negate mixed up> Invert is reciprocal ie 'one over' 1/x. Negate means multiply by -1. There's also a reverse checkbox in rangemapper. Percent often confuses people - percent in the XPresso window is actually decimal 0-1 eg 35% is .35 . Same goes for angles - degrees in GUI, radians in XP window. I prefer to stick with the units used in the XP window, then I know where I'm at. Some 1D teeth
  8. This is a project that came to being thanks to a free model from SketchUp. I've an interest in electronic traces on screens eg Lissajous curves, spirograph traces etc and needed an oscilloscope to display an audio sweep. Turbosquid wanted $100-200 for a really nice 'scope, but luckily I found a half decent one free on SketchUp that was usable with a few tweaks. The next problem was the math. The human ear is logarithmic ie works on powers of 2 (octaves on a piano is a doubling of frequency), so I wanted to use a log frequency sweep (linear just sounds wrong). I delved into exponential math and came up with this. The display and digital readout correspond quite well to the frequency heard. Screen is a movie used as a mat, font is Digital Readout Upright. 10MB file for screen audio tone/sweep generator free from here just a bit of fun really
  9. I don't think I've seen it mentioned here before, but I found a source of free 3D models yesterday - SketchUp 3D Warehouse. Seems to be a place where hobbyists upload their stuff, and reading through the T & Cs it looks like you can use the models for any non-commercial use. Here's a free computer I found I got a couple of semi trailer rigs, and there's also some half-decent city scapes eg NYC here the sketchup files have skp extension, and you can just drop them into cinema, although I've found that if there's a choice of versions an older one (say 2014) works best. apologies if this is old news - it's new to me
  10. @SolarPH what I meant was - something like: I need to control a light so that switch A does this and slider B does that. Your simplified version is your solution to whatever the original task was. Trouble is, I can't work out what the original task was from your solution. I'm also not sure what C motion has to do with things. A simple bit of python in a node can often be a solution to a complex truth table type xpresso problem. Not number crunching, just something like if A > B and C < D: output = blah elif A == B and D > C: output = blah blah else: output = fall back default if you get my drift
  11. Try my drone speed test - readout goes red over 3m/s. [ this is for 30fps scene ]
  12. @SolarPH sorry, but I think I'm wasting your time. Can't make any sense about what you are trying to do. Good luck anyway.
  13. You are thinking of the compare node - condition routes the inputs to the output, selected by switch ( < Mr Pedantic ). I had a look at the C4D file - it's a whole bunch of renamed operators and nested X groups with no description of what it's supposed to do, and not even 1 remark node. I'm an XPresso user, but the chances of me reverse engineering that code, working out what its function is and fixing it is zero. Maybe @SolarPH could post a simple file with just a few nodes explaining the problem eg I have inputs A, B, C and I need output D. Screenshots don't show data types. Color in XP can be tricky at the best of times - RGB, HSV, 360 deg, 255, % meaning decimal etc, although most things can be resolved with colorspace and vector2reals.
  14. When one scene is open, if you go File - Merge you can import a second scene into the already open one.
  15. There's lots of ifs and buts, but it might be possible to iterate thru the original cylinders, measure the dimensions and transfer this data to the same number of parametric cylinders using matrix for position. This file is just for cylinders (not tubes). The originals would all have to have their axis the same eg along Z ditto the replicants. The other hurdle is do you want to learn XPresso. Anyhow here's a gif showing some green polygon cylinders with random radii and heights and some identical red parametric cylinders sizes calculated in XP (dragged across for comparison). no guarantees . . .
