Question by dschmuck · Mar 31, 2019 at 11:11 PM · renderingshadersfloatingpoint

HDRP clamps output values at 65504

Hi! I am trying to get very large and small values rendered using the High Definition Render Pipeline. I need these values for auxiliary render passes (for an animation production) The values are in the order of something like 1,234567e+12 or on the smaller end 1,23456e-10. HDRP seems to clamp the values at 65504 on the large end and around 0.00001 on the smaller end. I guess the reason for that is that it is using half float precision. Is there any way of getting full float precision to render out values this large? I set up a really simple custom SRP of my own and there I had no problem rendering these kinds of values, but I would love to use the HDRP.
