SoftImage XSI Plugin v1.022e
Tip to change the old with the new one.
Uninstall the old addon with File -> Addon -> Uninstall
Select octane and press Uninstall.
Install the new one with File -> Addon -> Install
Select the octane.xsiaddon and press Install.
For changes in the UI, you must restart XSI/Softimage
If you have a saved scene with the exporter in it, you must delete the [c]Octane_exporter in the scene explorer.
Otherwise the UI change will not shown.
After that, Done...
A little video:

Changes:
Octane pre 2.3
This option is removed, pre v5 is stable enough.

Added:
Strands
Strands are now supported.
To use it, use a instand shape of your choice. The shape should be subdivided at the y axis.
The size is not 1:1 MentalRay, so that you should test it. XYZ scaling is not integrated.
Hard edges are not supported, to make a edge hard, insert a new edge, like SubD-modeling.

Some strands have a curious alignment.
For that, there is a parameter in the plugin under the "Export Configuration" tab, called "Strand Modifier".
With that you can correct them, i hope.
You should test it too, before you render a animation.

The instance shape can be animated. Shape animation not tested, should work, SRT animation works.
Particle colors are integrated too.

The technique to extrude the instance shape along the strand is not perfect, so that you can have some flipping.
But it is better then the MR one

Great! Thanks face!

Version 7.x is now available.

Have found a orientation issue.
Please download the new 2010 version...

Have seen that instance shapes as strands in Softimage 7.5 are not rendered, is that correct?
Otherwise, who interest it? Now it works with Octane

Hi Face! Runned into some problems today with ICE and Softimage 2011 SP1..

Im doing a test with momentum. http://opensource.studionestbarcelona.com/OpenSource/index.html

First of all I get an error when having a pointcloud without any instance shape in XSI when exporting my scene.. That one I can igonore or remove my ICE tree. But anyway, maybe there is a workaround so you don't get that runtime error popping up?

Now the weird thing is that I get a "MeshNode for rendering Ball_Test_04.obj not useable" error when trying to render a frame. But if I export the obj/mtl only it works fine. So that keeps me from rendering animations :/ I've attached the sample scene for you to test.

This is a still from my little test scene btw..

I get a meshnode error if i change the project.
Maybe you have changed the project name after the first export?
If you have, the name of the obj is also changed.
Octane read the information from the ocs file and can´t relink it correct.
The solution is to check overwrite existing on.

I know that you then lost your materials.
One solution is to use material macros, that you should do anyway for animations, and save the materials local on you harddisk.
Then you can load and use it, for other projects too.

The fastest solution to hide the runtime error is, hide the pointclouds where are no objects to render.
I will look deeper in it if i can solve it in automatic.

hope that helps a little bit.

Thanx Face! It seems like using material macros indeed did the trick

New problem Not that its a Octane/Exporter problem, but I wanted to share it anyway... Maybe someone has a tip or two for me..

Im doing a project built around shattering glass objects... Kratos/Momentum is very nice to work with, but when trying to do a simulation with momentum, I need to have all the shattered objects to be "ready" at the beginning of the simulation. However, I want only the "outer" surface on the mesh, since all internal shattered polygons completely wrecks the wonderful glass in Octane... I thought there is a scripted operator or something that sends out a ray from each polygon, and if it hits a backface normal on both its sides, it understands its a "inner" polygon and removes it, but I can't find anything like that on the net, and Im to crappy to do it myself ..

Here is my test animation, just to see that momentum works with Octane (and it sure does ..)... But you see the problem straight away.. Instead of a clean mesh, its built up of several hundreds of fractures, making both the glass object render wrong, and flicker..
