Hi everybody,

I'm having an issue with the Curvature Texture node. It seems like it has precision issues. I modeled a 1:1 scale hypodermic needle model. It's very tiny, about 0.8mm in outer and 0.5mm in inner diameter. When I apply a Curvature Texture node and set the radius to 0.001 this is how it looks:

• If I go ANY amount below 0.001 radius, the effect disappears entirely
• Reducing Ray Epsilon does nothing
• Dirt Texture seems not to be affected by this, but it does not give me the effect that I want so it's not an option as far as I can tell
• Scaling the object up by 10x does help, but I would prefer to keep this to real life scale for obvious reasons

Is this just an Octane limitation or am I missing something?

Thank you!

Hi,

which OctaneRender version are you using exactly?

And are you using Standalone or an integrated plugin?
