How do I center the Texture Coordinates with a negative constant?

[Unrhyme]

Hi, I have an odd problem in the unreal engine 4 material editor.
when I try to center uv coordinates with a -0.5 constant I don’t get the correct results.
Can someone tell me what’s going on?

Hey Kamyar1987 -

For reference, what is your expected outcome from this operation?

Hi Eric,

I am expecting to center the texture coordinates when I subtract it by 50% .
here is a picture of what I mean:

Hi Guys,

I’m also doing a migration from UDK3 to UDK4 and am getting the same issue. Does anyone have an idea how to go about getting the same results as UDK3?

The images shown above in Kamyar1987’s post illustrate that there is a very big difference in the behavior for the same processing logic.

Any help would be greatly appreciated.

Hello,

It works with multiply node.

Instead of multiplying itself by itself it would be better to use an abs node. This turns all negatives to a positive (so the black parts will become grey) and doesn’t make it exponential.
