Weird alpha appearing on 1 frame in animated sequence

Hello guys,
First post for me here (probably not the last one :D)
I just bought the plugin last week and start learning and experimenting with this awesome plugin.
I got something i can't figure it out.
I just installed the last version of the plugin 3.0 Alpha 10.1(OSX)
It seems i got some alpha appearing in some frames in the rendering. (actually always at least 1 frame) it already has been the second one, here is the third one. It looks a bit random.
I just use a c4d shader as texture background and allow alpha.
Is this a bug with the version ? or did i miss something ? :-)
Thx for your feedback and congratulations for the hard work.
Can't wait to have the final version in hands :-p

Hi there. Thanks and welcome!
What kind of shader do you use on background object? I need more details to figure it. Maybe a bug or known problem about rendering c4d shaders. Best to see your scene's related parts.

Hi, thx for your so quick answer.
Actually it's just a gradient with small turbulence but it has 1 layer to color it.
That could be the cause ?
Is this supposed to be fixed with the final release of the V3 plugin ?
Gradients are so easy to make with c4d shaders :-)
I read for background purpose octane shaders are not advised. Is this right ?
Thx

C4D shaders are cpu based so we can't run them directly. Plugin render those to images before gpu renderings. Layer shader is causing problems on this rendering. This is not a thing about final release. I don't suppose that can be fixed. We'll integrate open shading language for custom shaders rather than using c4d shaders.
