Let’s hope that Softimage does the right thing and fixes this properly so that we don’t need to have this conversation any longer.Mod authors - this is not a library or framework for your mods. That’s my view on the issue and I’m sticking to it. XSI zealots can make endless excuses about why it’s ok or not needed but at the end of the day users will decide to invest in applications that provide them with the tools that they need when the need them.
XSI MODTOOLS VIEW PROFESSIONAL
As I pointed out, most professional level 3D applications do provide this and the fact that XSI does not at this point in time only goes to prove my point this is a core design flaw and once again places XSI outside of the mainstream. Like I said, the XSI modeler is not designed with precision modelling in mind, if you need that it’s best to use another application which can provide this functionality.
XSI MODTOOLS VIEW SOFTWARE
Really, I don’t care about this enough to get into a debate over it but I think it’s unlikely that this issue will be fixed anytime soon because I’ve been using the software since the Softimage 3D 2.x days and the problem was an issue then and it’s an issue now and it’s never been sorted out… so forgive me but I’m not going to hold my breath on this one Well, I strongly disagree… in my opinion it is a fundamental flaw in the design of XSI – if it were not then a fix would be easy to implement, which it is not. I remember 3dsmax exploding rigged characters with this thing… “Adopt system unit scale” and bam! What you want to do if a model that used Meters is merged in a scene that is using Feet?
Would you be changing your units in the middle of the work? If yes, would you expect that XSI rescale all your data? (AFAIK this is the only thing that could be an issue). What would you like to see in XSI that make use of a unit system? As I said, they didn't added real world units as a feature in XSI, and I believe they are gonna take care of that, as lots and lots of people have been asking to. This is just an example of how units can work. To make things easy, 1 joule = 1 newton metre = 1 watt second, so I'm gonna round this up and say that my little particle has 0.3 watt of kinetic energy, and my fellow engineer would be happy. Just look my image and try the same values in the kinetic calculator Now if I want to say that my 1 Joule is in "foot-pound force", "electronvolt" or a "British thermal unit", I can just convert it.įor example, the smallest particle in the picture bellow, has 0.1221 grams, is traveling at 2.4 meters per second and it's kinetic energy is 0.3765 Joule. The equation KE = 1/2 (M * (V * V)) outputs the scalar value in Joules, and as you can see the results are precise. In the image bellow I just added the name “Kg” and “Meters/Second” to my attributes. the output is in joules (the default scale for Kinetic Energy). It calculates Mass and the Velocity vector. I could be wrong but I believe if they add units into XSI it would be a conversion layer between core data and user inputs.Īnother example of how you can use ICE and units. The problem is that people want to make sure they have a "rule" going on, and a "cm" or something like that on the side of scalar inputs. Real world units would be just a way to convert these existing scale. Therefore your light falloff length and everything else will need to fit the same scale.
If you model things with the scale of 1 SI = 1m, you will need to set the gravity to 9.81. If you look the gravity node it's set to 98.1. Just because it's not explicitly a metric system, it doesn't mean they don't take scale into consideration.Ī light falloff is based on SI units, object size is based on the same thing, bone length, everything is based on SI units.īoth the physX and ODE dynamics are using 1 Softimage unit equal to 10 cm. They have units and it's called SI units. It would be a core flaw if they had designed XSI based on cm, inches, feet or whatever you come up with.
