Lightwave collada does not export light color or spotlight cone angle animation. This lscript transfers the animation to the position, rotation and scale of a null so that whatever program reads the Lightwave collada file can reconstruct the light animation.
Right-click the link above to download the script(save target as/save link as). Place the script in the lscripts folder, "...Program Files\NewTek\LightWave 3D 9\Plugins\lscripts\animate", for easy access.
Image shows the animation graph for a spot light and the null created by this script. The scale null values are too small to see here because After Effects uses a 0 to 100% for scale instead of 0 to 1.0
The rotations HPB will each contain a copy of the light's cone angle. Color will be stored in the scale values and position will also contain the same color data. However, the position for color is only valid if the scene is exported with the default 0.01 scaling. The signs are set so that they are positive when imported to After Effects using the AECollada plugin.
First step after importing to After Effects is to fix the light type. Lightwave exports spot lights as point lights.
Image above shows the resulting expressions from pick whipping values from the light null's scale and xRotation values. The scale of the Lightwave export is not an issue.
This image shows the result of pick whipping cone angle and color to the light null's parent(Light_LITKF_Yr). The collada file was exported at a scale of one and so the color expression had to be divided by 100 as shown.
Use the pickwhip to link the animation to the corresponding light.
