![]() However in all my tests between RF and C4D, the PRT loader was always 100x smaller than the geometry and the RF imported particles, I tried saving. I tried using project units of metres in C4D, display units as metres, to check the scale issue with C4D, I created my default cube with metres as the project unit (cube = 200m), then I closed this and merged with a scene using cm as project units (cube = 200cm), the merged cube came in 100 times larger (correct result). I tried Bobo suggestion of making a cube and filling it with particles. Anyway… I tried what you said and it isn’t possible, the geometry scale won’t go any lower that 0.1 (RF 2013). Really? I’ve worked flawlessly with Realflow & C4D on many projects. There is your error, if you want to work flawlessly with Cinema 4D to RealFlow you have to set thr geometry scale in RealFlow to 0.01 in the preferences and axis setup to YZX btw The scaling will correctly apply to the Velocity vectors, too.Ĭreated a particle sim (all realflow scale prefs at 1.000) ![]() 100.0, and the particle cloud should come in 100 times larger. That being said, you can freely SCALE a PRT Loader - just go to its Coord. I will perform some tests with BIN files to see if the KC4D PRT Loader handles them correctly. When I loaded in C4D and increased the view percentage from 10 to 100%, the Sphere once again filled up bottom to top because the PRT Loader automatically converted the Max Z-up to the C4D Y-up coordinate system. RESULT: My PRT Loader’s particles still matched the C4D sphere because the PRT Loader found a scale factor inside the PRT file and scaled it up 100 times to be 100 units in radius instead of only 1.Īlso note that in Max, the Z axis is the up axis and the Max PRT Volume fills up the volume from bottom to top along it. *I saved another file (which had about the same size) and loaded that in my C4D scene which was still set to Centimeters. *I recreated the same setup, but this time my Sphere had only 1 meter (1 unit!) Radius, so I had to set the PRT Volume’s spacing to 0.04 to produce the same number of particles. *I went back to Max, changed the System Units to 1 GU = 1 Meter and Reset the scene. RESULT: My PRT Loader particles matched the C4D Sphere. ![]() *Then I created a default C4D Sphere that also happens to have a Radius of 100 cm. *I loaded that file in C4D using a default PRT Loader without any adjustments. *I saved the resulting particles to disk as a PRT file. *I created a Geosphere with Radius of 100 cm and converted it to a PRT Volume with spacing of 4 cm. *In Max, I set the System Units to 1 Generic Unit = 1 Centimeter. I tested the general PRT Loader behavior using Krakatoa MX v2.3 and KC4D Beta 5 (both Beta 4 and 5 support PRT 1.1 I/O). If it does not, it is a bug - the PRT Loader should assume a RF simulation BIN file is in meters and scale appropriately. The BIN behavior could be a bug though, because a BIN file containing a cube of particles with side length of 1 meter should load as 100x100x100 centimeters. Unfortunately, RealFlow does not export PRTs in that format yet (AFAIK), and BIN files don’t contain such data eather.īoth Krakatoa MY and MX v2.3 would export using the PRT 1.1 specification. The PRT 1.1 format includes a scale metadata component.
