I don't know if I'm doing something wrong when exporting an animation combining presenter + timeliner. I get a lot of problems like different lighting during the animation. When, for example, a machine appears, the scene gets a higher illumination and when it dissapears it goes dark.
I'm exporting frames (.png) and getting different lighting in each frame, happening wich you can see in the video (a scene that change continuously from clear to dark).
I'm importing a FBX file from a model in 3ds max, with ambient and distant lights and materials from recommended tab.
My guess is you have Autoexposure selected in the Prenter "Rendering" tab. This will cause the lighting to change from frame to frame, particulary on 4D because new content is added to the scene and the exposure is then recalculated.
