Hi, I would like to obtain the linear gradation chart by rendering, but the result image have the weird quantization at the high intensity area. Here I show the result of the rendered image and horizontal plot of the image. The red area in the below figure should be smooth, but it seems that the quantization becomes worse as the brightness increases.
I use UE5.1.1
I started with blank level then put the some of the Items (CineCamera Art, Cube with linear gradation as the chart, DirectionalLight, Landscape) on the scene with default parameters except positions and directions.
I used MovieRenderQue to output the image as 16bit exr.
I’m new to the UE so maybe I use the wrong settings for this. If anyone knows a solution, please let me know.
Best Regards,
