I’m capturing some normal information from a standard normal map (normal compression DXT5) to a render target but i’m unsure of the correct procedure.
Firstly it seems like i can only use render targets as a linear color inside of a material, secondly if i set my normal map to normal map compression settings the capture i get seems to be post compression, understandably, i’ve found a few topics about this and i’ve tried various uncompressed methods x2-1 ect. Or if i set my texture to HDRI or default i get pre-compressed render but i’m still limited by the linear color from the render target in the main material.
All avenues produce not quite right results. some closer than others, but i just don’t have the indepth knowledge of normal maps and compression settings to truly debug this.
Is there a proven method of capturing normal map information from a render target accurately?
