Getting/Converting Color Values From Lights?

Atomic · **Posted:** Thu Feb 12, 2009 1:56 pm

I am working with the AE3DExport script written by the urbanspaceman.

I am adding Blender functionality to the export section and have run into a snag on lights.

It seems there is no way to tell what kind of light an After Effects light is? Does anyone know of a way to detect the light type?

Also, working with the color of the light I am stuck. I know how to get the color

Code:

G.LIGHT_COLOR = layer.property("Color")

But how do I get access to the RGB elements of the color?

Here is my attempted Blender python output that fails.

Code:

"localLamp.R = " + G.LIGHT_COLOR[0]+G.RET+
"localLamp.G = " + G.LIGHT_COLOR[1]+G.RET+
"localLamp.B = " + G.LIGHT_COLOR[2]+G.RET+

I assumed the color value was an array, but I get undefined from the above code.

Thanks!

I think I figured it out.

Code:

G.LIGHT_COLOR = layer.property("Color").value

I have to add .value to my initial color fetch.

Hi Atomic,

Did you ever solve the light type issue. If not, try this...

Code:

function getLightType(aLightLayer) {
            
            //check it's a light layer
            if(aLightLayer.lightOption) {
               if(!aLightLayer.lightOption("Shadow Darkness").canSetExpression) {
                  //ambient light
                  return("AMBIENT");
               } else if(!aLightLayer.lightOption("Shadow Diffusion").canSetExpression){
                  //parallel light
                  return("PARALLEL");
               } else if(!aLightLayer.lightOption("Cone Angle").canSetExpression) {
                  return("POINT");
               } else {
                  return("SPOT");
               }
                  
            } else {
               return("NOT_A_LIGHT");
            }
         
         
      }

I'd be very interested if you get further with your AE to Blender script. It could not only prove useful as AE to Blender, but also as an intermediary for C4D to Blender, since I can't seem to get animating scenes from one package into the other.

Best,

Ben.
