Hi, I'm having a problem with GL trails from a moving gridshape that can be created by reducing the gl render object's erase. I can see the trails no problem when the erase is set to around .02 and when the gridshape is moving without a background, but when I move the gridshape in front of another gridshape the trails disappear. I incorrectly assumed this was a simple blend_mode issue or something but was informed by c74 support that getting layered render trails to appear would "require some more advanced patching". I'm not really sure what this patching would involve, so if anyone could point me in the right direction to layer moving gl gridshape trails over inert gl gridshapes I would greatly appreciate it.

Thanks

Phil
