PRISM – Realistic Post-Processing v2.4
“If possible, please buy the package to support the developer”
Four years after PRISM started the post-processing revolution for Unity, PRISM v3 has arrived. Now with core effect support in HDRP!
Rewritten from the ground up in native hlsl, and fully integrated with the Unity Post-Processing stack, PRISM once again sets the bar for what a post-processing system should look like in Unity.
NEW: ULTRA HD COLOUR CORRECTION
An all new colour pipeline based off CIELAB colour space brings PRISM in line with the world’s best colour correction tools, designed using photographic principles.
NEW: Chromatic Aberration & Barrel Distortion
Physically correct CA & Barrel distortion – built to closely mimic vintage camera lenses
NEW: NEURAL NETWORK AO (NNAO)
Created based off cutting-edge ambient occlusion solutions, PRISM.NNAO delivers near ground-truth AO at a low performance cost.
NEW: DEPTH OF FIELD
Reimagined DoF with variable bokeh shapes, PRISM.Bokeh is all you need to deliver a AAA-quality cutscene across all devices
Much more With a number of other effects including Bloom, lens dust, tonemapping, LUTs, godrays, noise & sharpen – if you’ve been waiting for a time to level up your game’s post-processing – don’t wait any longer.
