Where is mip_render_subset lens shader in softimage 2011?

[jerry7]

hi，
The declaration of mip_render_subset shader is in the production.mi , but i can’t find it in render tree nodes menu. Are there some bugs in Mi Parser?
thanks!

There really is something strange going on with that shader, luckily it can be easily fixed. When you start Softimage the mip_render_subset shader is not included in the list of Mental Ray Lens shaders. Once you press the refresh button in the Preset Manager next to Render Tree once, it magically appears...

After which it also shows up in the drop-down list in the Lens Shader Stack
(of which I forgot to take a screenshot)

mip_render_subset is not supported in Softimage, and by default it is hidden.

There's a OnStartup event in a factory addon that hides unsupported shaders like mip_render_subset and Glass. The refresh button in the Preset Manager doesn't fire the event, and so the unsupported shaders become visible. Oops.

There are five mental ray shaders that are unsupported.
I see two of them in that list (sib_slate and mip_render_subset).

Removed my previous post as the mistake on the WIKI-page I pointed out has been corrected.

Well done, Softimage
