Re: Approximated Sub Surface Scattering Demo - UDK
IIRC one of the later builds of UDK from last year added material functions. some of them are node based reconstructions of the photoshop layer blend modes, and various filters. it sounds like what vurtousic was looking for is already availible in stock UDK through one material function node. -
Re: Approximated Sub Surface Scattering Demo - UDK
The Idea was that the code they have in their custom nodes is more optimized. -
Re: Approximated Sub Surface Scattering Demo - UDK
Yeah, the Custom node is great. I've used it a few times to implement more complicated algorithms when I can't be arsed to translate them into a web of nodes (or, as you've already mentioned, when the HLSL method isn't available as a node). One thing to be aware of is that the Custom node doesn't compile as cleanly as the… -
Re: Approximated Sub Surface Scattering Demo - UDK
Thanks again guys. Ehsan Gamer - hang tight... i can't say anything but it's possible that what you want is right around the corner :) computron - Alot of those photoshop blending functions actually utilize the custom code node for the blends. you can look at the networks themselves if you are curious how they put them… -
Re: Approximated Sub Surface Scattering Demo - UDK
Finally got some time to mess around with rebuilding this in UDK. I was curious if anyone could offer some suggestions. I seem to get hung up on a few things. I only know real basic HLSL but I am pretty well versed in UDK. half3 vLTLight = vLight + vNormal * fLTDistortion; half fLTDot = pow(saturate(dot(vEye, -vLTLight)),… -
Re: Approximated Sub Surface Scattering Demo - UDK
As far as I'm aware, UDK doesn't allow you mess about the attenuation in the traditional sense (they even mention that in the Docs IIRC), it's extremely hacky, and half of the time, the distance node seems to act more like a glorified Dot then anything. I hope I am wrong, but all my test's so far concluded that Distance… -
Re: Approximated Sub Surface Scattering Demo - UDK
Hey guys, thanks for all the comments! Some of you asked about tweaking and stuff like that. I definitely had to tweak the shit out of it to get it to look alright. for instance, there's an instruction in the shader that "distorts" the incoming light based off of the normals of your shader, and it didn't look that great at… -
Re: Approximated Sub Surface Scattering Demo - UDK
Not as far as I can tell, as Strumpy doesn't seem to expose a light direction node. Here's the Unity shader I used. Now I'll try to stop derailing Virtuosic's thread :) -
Re: Approximated Sub Surface Scattering Demo - UDK
Then what would you substitute for light attenuation in that code? -
Re: Approximated Sub Surface Scattering Demo - UDK
This is why I wish my brain can work with code. Nice work!
