Black triangles

[stir]

Hey Forum

I am expecting some od artifacts in my renders. black triangles to be more precise.

I was rendering everything with DL kernel and everything looked nice and smooth. Then i change over to Path tracing for more endgame rendering.
Thats when it happend. (PMC also looks good)

So i think, ok, maybe its the mesh!
So i create a brand new cylinder and applies the shader to it.
the artifacts is still there!

Ok, must be the shader then.
Create a brand new Octane diffuse material...
its still there!!

Now i start eliminating objects and shaders in the scene....
in the end i have deleted everything in the scene except the fresh cylinder and that new made Octane shader.
now i am tearing my hair out....and ye--- i have tried turning it on and off again.

So at this point i'm starting smashing buttons all over the render interface....this button....this button...this button.... NO!...what about this.....or this...

And that's when it hit me! like a pack of raging elephants!
i haven't tried changing the cameras. ( in my defense, i haven't used Cinema4D much more then a week so i am in the middle of a learning curve still) im a MAX user <3

So i create a fresh camera... sadly... still looks like shit. so i add the octane tag to the camera hoping that might solve something.....haha... nope, made it even worse.
Then i change to the "Default camera" the camera i assume Cinema4D users use when they are flying around in there 3D scene doing there mombo jombo.
and would you know!
From that camera it renders without the artifact.

at this point i'm crying, and since my manly manly-hood is already broke i guess i can break my self-esteem some more by asking for help.

so if anyone have encounter this before or know a fix to this, or even just want to laugh at me for beeing a big noob that fine too.

looking forward to hear from you

Cheers

No problem, nice to help you. But it's a common pitfall on plugin without knowing the some behaviours, limitation and settings to dive into deep water. Please don't ignore video tutorials. See C4D/tutorials forum.
Have a nice weekend.
