Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

[Closed] [Bug]:Refraction in material layer doesn't work if connected via "Use Material Attributes"

Seems like refraction doesn't work if material layer is connected in the final material via "Use Material Attributes". To make it work the layer needs to be broken to material attributes, material has to have unchecked "Use Material Attributes" and all attributes that are used in the layer manually connected to the final material.

Hi Tomas,

What attributes/nodes are you using in the GlassLayerTest node? Knowing what that node does will help me to better assist you.

The glass layer is using the following attributes: - BaseColor - Metallic - Specular - Roughness - Opacity - Normal - Refraction

edit: wanted to make that a nice list, but somehow the edit doesn't want to save the list :)

Hey,

Just want to report this bug is still present in 4.10.1. Its been nearly 2 years so figured I would re-report it. Refraction does not work when material uses [true] use material attribute.

I had a unlit translucent material using emmisive, opacity, and refraction. Breaking the material function and plugging in works.

Hi Daniel,

Please open a new post in the Bug Reports section so we can get this tracked properly. This is an old, archived post from our beta users, and enough has changed since then that I'd like to get fresh eyes on it. Include as much information as you can. I'll get someone assigned to investigate and we'll go from there. Thanks!
