Question Flip a decal projector?

2022.2.7f1

How do I flip the fish so that the face points to the right?

The different decals are taken from a texture atlas, and I use the Tiling and Offset setting in the URP Decal Projector component so that the correct artwork is picked. In my use case, there is a a projector on the left side and one on the right side of the aircraft. I want to horizontally flip the right one.

I have tried changing the scale mode to "Inherit from Hierarchy" and then setting the scale of the transform to -1 on various axis. Also tried setting width to a negative value, and tried changing Tiling to a negative value. No luck so far.

I have considered editing the Shader Graph shader. But I can't really figure out what kind of UV tricks that would help me (I'm a novice with shaders). The fact that I'm using an atlas, instead of 50+ individual images for the different artwork, might possibly make it even more challening, but I don't know.

Thanks in advance!

 

Thank you, it worked! My images are collected into an atlas, so just flipping the x-tiling didn't work, but as you touched upon, adjusting the x-offset with some black magic math made it work.

As you can see in the screenshot, the fish is now very happy.
