Hello,

I'm relatively new to Redshift and have encountered a problem. When I rendered this geo with Mantra, I got a clean surface and no problems. When I do so with Redshift, I get these stripes. Unfortunately, I don't have enough experience to find a solution. I already searched for a few hours for solutions. What am I doing wrong and how do I fix this? Thank you for your advises!

Did you try adding a “normal” node to that geometry?

No, I did not before. But that solved the issue. Thank you! Is it possible that you tell me what background knowledge I am missing that I did not come up with this solution by myself?

You can read about the normal node here and watch the video explaining the cusp angle. Sometimes geometry that is imported needs to be “fixed” to display and utilized correctly.

No problem. I'm still learning too. Don't be too stressed about learning Houdini. Just keep at it and look things up to understand how you want things to work. Slowly, you'll learn how to navigate and it'll come easier, but just keep spending time…like guitar lessons!!! LOL

Are you coming from C4D? Reason why I ask is that typically C4D automatically adds a Normal and UV map tag while Houdini doesn't automatically add anything. I think many who come from C4D can get confused from this since C4D shields them from ever really having to deal with Normals and UV maps for the most part.
