Hello everyone!Im trying to get into Unreal VFX since I have close to no prior experience with it and the industry is only asking for UE technical artist - gotta pick up the paceI was looking for references and I stumbled with this CGHow tutorial. When it comes to setting the refractions, I have one big issue: it simply doenst workThis is my current graph:There doesnt seem to be happening any kind of refraction; there are no visible changes in the effect preview nor the game scene. This is a comparison with my result VS the tutorials:For this effect, I also generated three sets of round Normal Maps, although none of them seem to work:Things Ive tried unsuccessfully:I tried using refractions via using fresnel nodes, but still dont seems to workStraight up hooking a B/W texture, still nothingChanging the Refraction modes; tried PixelNormalOffset, 2D Offset and IoF, but none seem to workTrying with color textures instead of normal texturesConverting normal maps to color maps - the engine wont allow itTrying with engine-provided normal mapsChanging scalability settings to highAt this point, I think there is something wrong my project setup; is it possible that refractions dont work if the project is not set to Maximum?
