[Closed] RTT Switching between Scanline and Mental Ray AO Bake

Hey Everybody,

I am trying to figure out how to tell the RTT system to render out an AO map using a light map when using the Scanline renderer and Ambient Occlusion(MR) map when using Mental Ray. I can get it to kind of work by using some like this…

if foo = true
(
  Run some code..
)

if nfoo = true
(
 Run some other code...
)

But this codes cause a lot of issues and I think it’s because the way above the script just runs it all. Now if I do something like this…

if foo = true then
(
  Run some code..
)

else if nfoo = true then
(
 Run some other code...
)

The first part will run but it will not run the second part of the code and I have no idea what I am doing incorrectly. Here is the main code that I am working I have cleaned it up so that it’s not too long to look at. Yes I know it could probably be coded better but I am still in the learning process.

Global SLR = false
Global MRR = false


-- Makes sure that we have only one window open at a time. 
if (( mainRoll != undefined) and ( mainRoll.isdisplayed)) do
(destroyDialog mainRoll ) -- test if dialog exist 

--Moved this up here because it was causing lots of errors down below. 
--global n = $.name as string

I think I am pretty close on this but I just have no idea what I might be doing wrong. As always any and all advice would be greatly appreciated.
