scale in XSI

[ibra]

how does scale in xsi work and does it affect lighting? should i model everything according to real scale? and how do i know real scale i XSI?

Ah, the endless question. This one never seems to go away and I have yet to hear a definitive answer. Everyone seems to have a different idea.

Yes scale can have a big impact on things in Softimage. Rigging, shading, simulations, shaders, displacement can all be dependant on scale.

Speaking for myself and the people I work with we tend to stick to the rule of 10cm is one Softimage unit. Just avoid making anything way too big or way too small.

found this: Throughout Softimage, lengths are measured in Softimage units. How big is a Softimage unit? It is an arbitrary, relative value that can be anything you want: a foot, 10 cm, or anything else.
which is useless really...


but then for simulation, they write : Always keep the scale of Softimage units and your scene objects in mind when designing a rigid body simulation. As with other simulation calculations, scale is crucial when dealing with rigid bodies. Before you start to do a rigid body simulation, you need to define what unit of measurement a Softimage unit will mean in your world: 1 meter, 10 cm, 1 cm, 1 foot, etc. And you need to model your objects in reference to this and to make sure that their mass or density also reflects this.

i think sticking to your rule of 1 XSI unit= 1 cm is best for now


anyways... found this, hope it helps: http://zoltanocsai.blogspot.hu/2012/08/kcs-iceruler-091.html

1 SI Unit = 10 cm recommended (.1 metre)

Are you using IES Light profiles?
