Hi Patrick, if you don’t want to manipulate the image any further than just rotating it, you don’t need to use the Image Transform! Just use the „Rotation“ input from the Billboard patch itself. The Image Transform may need to render the image and therefor you will have an unnecessary additional render step costing GPU performance and Video RAM.
On the other hand, if you want to stick with the Image Transform, you can setup the Billboard to render in either „Original Size“ (which keeps the pixels 1:1) or you may use an Image Dimension patch to read the „new“ image Width after rotation, and pipe this into the Width input of the Billboard. A third option would be to use the „Image Crop“ patch to crop the rotated image back to its original size, but this will cost another render step you want avoid.
