Re: [Cin] possible patch for x265 on cmake 4.0?

Unfortunately you are asking precise things that I am not able to answer. Looking at the plugin code (I understand it much less than Andrew, practically 0) I saw a part where it uses 8- and 16-bit integers and uses floats for RGBA-FLOAT. It just seems strange to me that the Color Space plugin, which as you say should not be about clipping, shows clipping with the two Blender Program test you wrote. However, the only difference is putting a sentence, in the manual, in the description of the plugin; it is certainly not something to waste time on.
