Hi,
I am using Substance Painter to paint textures on my object, I have a portion of the object that is glass and I have painted the opacity map and it looks good but when I bring the textures in Houdini I am not getting any refraction effects that we typically get in a glass sphere. I am connecting the opacity map into opacity color and also applying inverse map of opacity to refraction color. But I am not getting proper refractions. Opacity is working fine.
Please help.
