Opacity mask / distortion shader query
So I've started getting my hands dirty with UDK materials, and I'm encountering a situation that I'm not sure about. I'm trying to add a glass effect to the windows of my scene. I'm trying to add some subtle distortion to the glass, but I don't think I'm doing it right. Here's the (very simple) setup - I've used a… -
Re: Opacity mask / distortion shader query
mh. maybe you can use a greyscale image to drive the distortion, only ever used normal maps. and yes, lit translucency is supported for quite some time now. just not sure about dynamically lit translucency. -
Re: Opacity mask / distortion shader query
Really? I was using this tutorial by Hourences to refer from, and although it's for an older version of the engine, it doesn't mention anything about normal maps to control distortion. Also using that same page as reference, I was using masked as opposed to translucent blending as the glass needs to be lit by the internal… -
Re: Opacity mask / distortion shader query
you need a normal map to drive the distortion and not a greyscale image. i don't think masked blend mode supports distortion. you'll most likely have to use translucent in your situation. other modes support it too but might not be the best choice if you want other surfaces in the same material. -
Re: Opacity mask / distortion shader query
as far as i know, you cant distort anything that is using Blend_Masked. It either needs to be translucent or additive. there is a setting (ill have to look it up) to get translucent objects to not render through themselves (so that you dont see geometry inside or behind it even with a white alpha). but pretty much set it… -

Check out DM_Deck stuff, Im certain they have some distorted glass material... -
Re: Opacity mask / distortion shader query
Thanks, Oniram, that did the trick. The glass is distorting quite well now that the blending is set to translucent, though I'd be interested to see the settings to only apply the transparency and distortion to the alpha and not the rest of the diffuse, but at least I'm on the right path. Thanks again!
