Does anyone have a way to animate the value of the DMC Color Threshold over time? It cannot be animated directly, and it does not appear in the Wire Parameters Dialog as a controllable attribute.
I want to do this because I have a group of objects in the scene that fill about 30% of the HD frame for most of the shot, which renders in a reasonable amount of time. Then for the last ten frames or so the camera flies in and they fill the entire raster frame, making render times sky-rocket to unacceptable times. I would be great to be able to simply animate the Color Threshold for those last ten frames.
Sometimes you can put a floatscript controller on a parameter that can be animated and use it to animate a parameter that can’t. In this case you can animate the cylinder height of the override camera of the V-Ray render. So if you put a floatsrcipt controller on the height you can use it to animate the color threshold.
This seems to work for me:```
(
renderers.current.camera_cyl_height.controller=float_Script()
renderers.current.camera_cyl_height.controller.setExpression “renderers.current.gi_irradmap_colorThreshold = (currentTime/100) + 0.1\n90”
)
