Hi Epic,
I’m here to ask you, please, about making the Unreal more basic particles work with RT technology. Something like smoke should be one of the first things to make compatible (I think!). Currently, if you want to have it, you need to disable RT translucency, disable refraction, and disable Translucents in reflections, so, of course, you won’t be able to use a good glass RT material in the same scene:
PS: I love when this forum becomes a nightmare when trying to post any image.
