Why is my texture clipped in post process material

[AJMW (Arvind Jayaraman)]

I am noticing an odd issue that hopefully someone can shed light on.

I am trying to use a texture within a post-process material. I imported the following texture into Unreal Engine which is a 1024x786 png image

However when I used the texture within a post-process material and view it in a render target I notice that the image is clipped / shifted by a bit. Why is this happening? What can I do to rectify it?

Here’s the post process material I created to simply connect the texture to the emissive

and here’s the odd result I see in the Render Target 2D that receives the post-processed material (which is also 1024
768)

Notice the right side of the image getting cropped somehow out of the frame. How do I avoid this? Is it a bug?

Hi,

Can anyone please help out? I am still stuck and waiting for some hints to move forward.

Finally, found the issue. The default UV Coordinates are the UV coordinates for the ViewSize which “may not” be the coordinates needed from the texture. So a simple UV scaling operation like the one shown below yields the expected result in the scene render target. Perhaps this could be made a bit more clear in the documentation of UE.

Thanks very much for posting the solution! This saved me some time, tested and working in UE4.15.2. I agree, it would be great if this was mentioned in the documentation for Post Process Materials.

this is just stupid bug! actual solution for UE4.18.
