Web29. mar 2024 · In Blender 2.92 Cycles, I'm trying to model a quartz prism with physically correct refraction of a beam of light cast by a narrow slit (not worried about the color dispersion yet). But when I render it, the beam of light doesn't bend, and it doesn't seem to exit the prism in any meaningful way at all.

Web24. aug 2016 · The difference is that the glass BSDF is essentially a mix of a refraction BSDF and a glossy BSDF - it reflects light as well as refracting it. The glass BSDF is designed to make glass and similar materials easier to simulate - otherwise you would manually need to mix a refraction BSDF and a glossy BSDF. WebThis BSDF model is one of the most complex handled by Ocean. Simulations can take a significant time to resolve, as they generate a very large number of significantly contributing paths, taking into account roughness, polarization, refraction and dispersion, combined with advanced interface laws such as coatings.
