Hi
"The rendering progress screen, which is normally in HAM8 greyscale I believe, also contains a thin (18 pixel deep) 2-color overlay with text. This is a separate screen I think, because the curser moves 'behind' it. This strip is located at the bottom of the render preview screen. However, using NewMode's screen positioning gadget doesn't seem to make things work. My Voodoo screen is switched off and it all goes to the native modes on the 15KHz monitor."
and its this that is complicated to manage.
But i've managed to use it anyway . . .the Render in progres crap thing, its a 640x18 separated screen theat you could promote to some resolution about 640x480 and see it using the depth AmigaL+M.
Its not the best but . . .better than nothing :-)
BTW . . yes i'm using the CGX plugin too
EDIT- "When rendering is complete, it usually switches to the 24-bit Picasso screen, which I don't think can be promoted as such(? ? ?)."
?!? this is strange IMHO
when the CGX rendering screen is completed, you have to click on it and hit on ESC to exit.
At this point if you are on a black screen click again on it and the on ESC.
At this point, you should be on the Layout screen.
As already said, this is a little bit annoying but . .
