how to do solid layer transparent programmatically in after effect sdk in c++ ?

[shachar carmi]

after obtaining the AEGP_LayerH of the trager layer, either:
1. use AEGP_SetLayerFlag with AEGP_LayerFlag_VIDEO_ACTIVE.

2. use AEGP_GetNewLayerStream with AEGP_LayerStream_OPACITY, and then use AEGP_SetStreamValue.

In After Effects i have taken a solid layer and on it I have added an Avatar as shown in the attached screenshot.I want to background of the solid layer to be transparent. It means there should be no  color and no other thing in the background, only my avatar should be visible. How can i do this with programtically in after effect sdk in c++. please tell me?

are you the creator of the Avatar plug-in? if so, rendering on a transparent background should be trivial.

if you're just using the plug-in, then neither the C SDK or the javascript API are the answer. this would be a question to direct to the plug-in's vendor.

Not used this before, but a few weeks ago, I stumbled across this guide:

https://buildmedia.readthedocs.org/media/pdf/after-effects-scripting-guide/latest/after-effects-scri...

On page 163, it suggests: var myProperty = myLayer.opacity; 

[shachar carmi]

that's the javascript API, not the C SDK.

if using a script is good enough for your needs, then it's a much easier route to create and maintain than c++ plugins.
