I'm testing advanded camera in v 9.6

------------------------------ see the screen shot numbered " 1 ~~~ " that I attached

On top-left side , you can see the lens shaped object is used as "custom lens" by the uv coodinate.

I pushed F9 and got "image viewer's image" by lw native renderer
----------------------------- see the screen shot numbered " 2 ~~~ " that I attached

I added kray and pushed render frame button and get "kray rendered image"
----------------------------- see the screen shot numbered " 3 ~~~ " that I attached

I removed kray and pushed F9 ( not shortcut but menu button )

and I encountered kray preview which was already removed
and after this first "F9 ignored" , I can not get back image viewer !!! until I restart lightwave
I suddenly checked render setting and only found image viewer is at place. every setting is normal.
I even can not use classic camera as well. the lw native render command is ignored
without image viewer I have nothing to save as image file.
-----------------------------
IN SHORT.
it means once I use kray in advanced camera mode , I can not use lightwave's native renderer again .!!

I should use both renderer in advanced camera at the same time, for boolean shader kray does not support.
what make this ? is there any solution ?

Have you checked the Renderer Choice box in the render globals panels?

I did not know this option !! thanks.
there is !! renderer exchange function. under the render tab in render global.
I exchange it to "lightwave renderer" and F9 work again.

quite stupid reason for me. ah..
but I remain this post possibly for some one encounter this trouble.

I suggest you to map KrayFrame to keyboard shortcut ctrl+F9. Otherwise your scene does not save prior to render and you can get problems.

That's what I figured. when i press F9, it doesn't use the new parameters I entered in Kray, so I ended up teking the habit to always press the button by Hand on Kray's UI.
