SP to UE4 alpha help

Cbonez888

Sorry but I cross posted this in the UE forum

Hey all,

Having issues reproducing the result I get in SP2 in UE4. I'm unable to get the clear plastic look i'm going for, instead it looks ghostly and black where it should be greyish, it's also not reflecting any light. I don't think I'm using the opacity properly. I've looked online but couldn't really find any direction except adding a reflection probe which I did but to no avail.

Also, I'm guessing it's the difference in shaders between SP and UE4 but the texture in UE4 is much more yellow than SP. Kicking my tires on trying to match it best as possible.

Cheers,

Make sure you add a fill layer at the bottom of your layer stack with a white opacity channel, if not, empty areas (not painted) on your opacity will be filled with black, resulting in a very transparent opacity.
For your diffuse color, make sure the texture is set to sRGB in Unreal, and make sure your roughness/metalness texture has sRGB unchecked.

That's alot Jerc,

Gonna give that a try now, as for the diffuse color it is set to sRGB and the roughness/metalness is unchecked

Adding the white fill layer worked! Thanks man, but I'm still having issues catching light. I do have a sphere reflection capture object in the scene. Any ideas?

If I remember correctly translucent materials can only sample reflection coming fro SSR is recent version of UE4, or have no reflections at all in older versions. That's a limitation or UE4 unfortunately.
