Broken: Current builds (since the addition of Brecht's new bevel shader)
Worked: none so far
Short description of error
Adding Brecht's awesome new Bevel shader to transparent materials makes them render a lot darker.
The darkening becomes more prominent the more samples you use in the Bevel shader.
Exact steps for others to reproduce the error
- Open this blend file:
It's just a simple cylinder with a thin wall and a Principled shader with transparency and a constant white environment.
- This is the result:
- Go to the cylinders material and plug in the Bevel shader. Render again.
- Now you get this result:
- If you set the samples in the Bevel shader to something like 16 the cylinder becomes completely opaque.
