Title: Glass Jagged Refraction Issue
Post by: raglo on June 18, 2020, 03:28:27 AM
I'm getting these weird jagged lines with the stock glass material in Keyshot 9. The screenshot clear shows the problem. In case it's not clear on the screenshot, the jagged edges appear when looking at the back of the cone through the front. I've also attached the bip file. I hope someone can help me troubleshoot.

Details:
Keyshot 9.3.14
macOS 10.15.5
MacBook Pro 16,1 (2.3 i9, 5500m 4gb, 16 gb RAM)

Hi,
It's your model that's not correct. Redraw it and export it properly. That's what I did. I'm attaching the .bip.

Hey thanks a lot. Could you please explain what you mean by redraw and export? I'm using Fusion360 with the keyshot export plugin.

Hi there,

May wanna try to export the model separately. IGES or any other nurbs format will assure a smooth parametric curved look.
STEP, FBX and obj may triangulate the model using polygons.

Like IGES, STEP is also a NURBS format. Of course, everything that gets brought into KS gets turned in to a triangulated mesh in the end, but STEP is will retain NURBS info if you check the box on import.
