Why my texture becomes black in certain regions? I'm trying to implement some kind of Ian Hubert style. I use a PBR texture for the wall, mixed a brick PBR texture with a moss PBR texture and used some other image textures for the windows and such. As you can see in the following image, the texture gets black for whatever reason:


The same thing happens in the viewport preview (it's a different version of the scene):

How do I mix the textures:

As you can see the texture becomes black at a certain angle. The blend mode is set to opaque:


Interestingly, there is no issue when using Eevee:

I don't get why is this is happening and what I can do to get rid of those artefacts. Can you guys please give me any advice or ideally some suggestions how to fix this in cycles?
in case several textures are overlaying - I assume the green parts contain an alpha channel - have you enabled the Blend-Value within the Render-Settings?
