Glowing Edges on Alpha Channel Problem

Hello, I get some glowing edges in octane for cinema 4d when enabling Alpha channel inside the octane settings below you can see a screenhoot. How can I get rid of the glowing edges ? When I disable the Alpha Channel i get no weird glowing edges. I want to composite the render later inside after effects to create a different background but with the glowing edges in the alpha render it looks very bad.

This pixels will not be visible when you use alpha on compositing software. This is asked many times.

Hi Aoktar, I rendered now a scene and noticed that the pixelated edges still appere in the multipass render. I get the edges also when doing the compositing inside After Effects. It's very important for me that i have no pixelated edges in the final render, because I can't do a nice compositing with the pixelated edges. I attached also my render settings and what options i have enabled for the multipass.

Please attach a scene and I'll show you how to get good results. Render settings are fine by default against most problems. Please try to check it in a new scene before post.

Hi Aoktar,
Here is the
Scene File, I could not attach the file here in the forum because it's to large that's why the link. I noticed the hotpixels also on other projects. The scene file used to illustrate the pixelated edges, is created by
Glass Hand Studios
I just used the project to do a test render and to illustrate the pixelated edges when I render in Octane.
