This SHOULD technically create those shadow and lit areas as mentioned before… When you use the Blender principled bsdf shader settings to set up a glass material on an object, Blender automatically gives the object shadows which is correct like I mentioned above! You have to enable reflective and refractive caustics properties in the render settings so Blender can try to to pass light through it correctly. Essentially this is where refraction and caustics comes from (in very simple terms). This essentially creates shadows and light areas. With glass in real life light passes through it but not in a straight line. What’s wrong with glass shaders in blender? Blender eevee glass materials can be a little tricky sometimes

We will cover Blender eevee glass shader in another blog.

Note: this blog will only focus on Blender Cycles Render Glass. For Blender you need to give it a little nudge. Glass is one of my biggest bugbears in Blender so I’m going to make a blog to show you what you need to do, and what you need to look out for.įor other render engines, if you tell something is Glass material, it acts like a glass material. One of the key materials or shaders and used in nearly every render, and yet with Blender Cycles it unfortunately falls flat on its face.
