Hello,
I’m running into an issue where objects (or particles) with a material set to a blend mode of Translucent aren’t distorted when seen through an object with refraction set. Objects (or particles) set to a blend mode of Masked do still get affected by refraction.
Steps to re-create:
- Create a new blank project.
- Create a new material (M_Refraction) and set its blend mode to translucent.
- Give M_Refraction an opacity of 0 and a refraction of 1.4 (So it’s noticeable.)
- Create a second new material (M_Transparent) and set its blend mode to translucent.
- In the level place an object with M_Refraction assigned to it in front of an object with M_Transparent assigned to it. The object with M_Transparent won’t be affected by the refraction of the object with M_Refraction assigned to it. If you change the blend mode of M_Transparent to masked it will start being affected by the refraction of the object with M_Refraction assigned to it.
While trying to troubleshoot this I came across this question:
http://answers.unrealengine.com/questions/73313/refraction-not-working-on-particles-in-lit-mode.html
in which the person asking the question was using a material with a blend mode set to transparent, so I think what I’m running into is not the expected behavior.
Thanks!
