Hehe...
Now its time to let the exporter write a texture for use of some things

I hadn't even tried out the last one from the 3rd yet. This is moving fast. When do you anticipate that Mental Ray could actually be replaced with Octane? I see it heading that way if the progress keeps up.

The ultimate would be at least a simple shader conversion.

A realy good question.
The main problem will be to manage great scenes with a lot of textures which have all in one more then 6GB.
That would be the time for MR, i think...
All others what can handle a tesla or quadro can do in Octane.

Maybe a solution to saving memory, is to delete polygons that haven´t a effect in the scene.
But this would assume that the scene will be precalculated and then send to octane.
Maybe a backraytrace methode...

Shaders to implement would not be the problem, i think.
The problem is, that Octane use the scenefile for materials, so that you can use the shaders only for a new scene.
And to setup the materials in Octane is much faster as in Softimage. You see the results and the export isn´t required.

I haven't had time to check the plugin in the last week, but is it now possible to set materials in Octane, then go back to XSI scene, then back to Octane and still have materials set properly. I think the last time I tried, I kept losing my settings. There's some confusion for me as to when I should check or uncheck "overwrite existing".

When you have a existing project and you want to create a new one with the same name, then you can use the overwrite option to create a new one.
Because without the option, you must ever create a new one and then you have 25 projects where you has tested anything
Thats the sense behind them.

Forth and back is possible when you not use the overwrite option, while Octane save the materials in his scenefile.
Changes in the material in Softimage then not work. But creation of UV´s or geometry changes should be work.

thanks.

I just cleared up some time so I want to really dive into the xsi/Octane thing for a few days and see what I come up with.

How are you lighting your xsi scenes when testing? Just the daylight or HDR map? There's no emitter shader yet, I think.

I have no favorite.
Sometimes the sunlight, sometimes a hdr. For the most things i test, i use no light.
For UV´s, geomerty or materials it has no matter. Only for normals i use a light.
While this are the only things i test with the plugin at the moment

I'm all straightened out with the materials now. Working great for me. I'm so impressed with Octane, I think I need to get the 480gtx(I have 280 now) to get an even better speed boost. I'm working on a simple job that I might be able to render fully with Octane and the plugin.

We really need some emitter materials, because its a little challenging to chase after a certain look with just HDR and daylight.

Good
Materials aren´t so weired now as with the buildin obj-export.
Wait for the next update.
Ok, it has nothing to do with materials, but...
