HLSL - Scene Texture in a custom node ?

Froyok

I'm currently testing some little things with the HLSL custom node in UDK and I'm wondering if there is a way to use the Scene Texture Sample node as an input ? I would like to perform something like a blur/sharpen on the scene texture.

From what I have read, the Scene node is already sampled which mean is ouput is a float4.

Is there a way to transform this floa4 into something usable for a Tex2D function ?
I must admit that I'm not comfortable with HLSL.

Hey Froyok, i know this is a necro post and all, but you can access the SceneTexture inside the custom node by using the following code

float3 output = tex2D(SceneColorTexture, ScreenAlignedUV(UV));

Ho ! It's never late, that's sweet to know !

i forgot to mention that UV is an input... just plug a regular uv coordinate node into an input and call it "UV"
