Shading problems with ray tracing

pes

Hi there

I'm having some shading problems with ray tracing feature

Without raytracing model looks smooth, but with it weird shadows appear on wireframe edges. Like it ignores the model smoothing.

Is there a way to fix it?

When using the ray tracer shadows are cast from the mesh's geometry and are very accurate. If you have a low poly mesh with somewhat jagged topology, this can cause faceted shadowing. You'll generally see the same results in offline renderers & other ray trace engines.

You can try sub-dividing the mesh or adjust the Common >  Shadow Offset setting in the Render object to alleviate this.
