Need help with problem to tile uv of global post proc material texture

I try to make the basic vr feature of stereo screen by tiling the u value of uv to 2.0f in post proc material, but problem shows up like this:


what’s the problem? I don’t belive it’s a bug.

Any idea will be appreciated and thanks in advance.

Its a bit hard to see from that screenshot. You’d be better off plugging the TexCoord node directly into the output for debugging.

However my guess is that it is a know issue with the editor viewport resizing and how the UV’s are reported. I bet it looks fine in the HMD.

Edit* Looking at the image again it looks like a clamping issue, check the properties of the scenetexture node.

Is it work find on your PC?
