Sorry its a bit dark but colour of the base is exactly how it should be. Simply used the base shader, set the material to refract with full gloss and BOOM, exactly what we want. The difference is immediateĪs another comparison. In comparison, here is a photo of real glass (encase you’ve forgotten what glass looks like). Basically, without setting my computer on fire, this is the best that comes out. The problem with this though, is that it is very slow, and 9 times out of 10 you end up with a horrible dark shadow at the bottom of a glass which doesn’t look to me very much like refraction! The shadow is far too strong for any refraction object.Īs an example here is a glass in Blender and just look at that horrible dark grey base! This is using 64 max light bounces for all light path types, refractive and reflective caustics turned on, clamping turned off.

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.
