Additive blending with particle sprites

This is common technique used to create explosions and glowing effects.  It's a feature in particle systems available in motion graphics software and other 3D packages - but doesn't seem possible in C4D by conventional means, so I'm wondering can it be implemented through the SDK.

This is the general idea..

For example, with the SDK is it possible to detect the underlying pixel colour it is rendering to - and add its value to the final pixel.
Thanks,

Hello,

if you want to edit or work with the final image to add some additional post effects you may have to use a VideoPostData plugin. This plugin type is only available for the C++ API.

Best wishes,
Sebastian

Thanks - shame, hope things like this are available in the future though..

for reference I found help here using conventional means
