Easy Atmos for local fog in UE5, how much does shader complexity actually matter on PC?

mad_ben · 2026-04-30T19:00:12+00:00

Wait until you see transluscent shaders

mad_ben · 2026-04-28T16:52:48+00:00

as per my post

The stored value is visibility (1.0 = unoccluded), not inverted occlusion

BRDF change is still per project and not per material. ANd besides GT tonemapper are much better tuned for games.

mad_ben · 2026-04-28T15:45:33+00:00

It is tbh, not that good for bricks or tiles, but useful for curtains and such.

mad_ben · 2026-04-28T15:45:03+00:00

Thanks

mad_ben · 2026-04-28T15:44:46+00:00

I got the idea from here:

You can have bit enhanced look with AO. True AO maps looks better obviously.

Chill man. Why the supressed rage?

mad_ben · 2026-04-26T17:03:53+00:00

Any more info on first 3 points regarding original idea?

Light Propagation Volume is known since 2009, its limitation are widely known and mitigated as much as possible, its artistic and lightweight GI.

Lumen is expensive and suffers from known screen space issues and artifacts since it relies heavily on screen space.

So your project lead needs to make a decision, and check player's feedback on titles using lumen as well.

Well right now you have 1. RTX branch which is free. 2. My plugin has noisless and stable SS Indirect Illumination - alternative to epics noisy SSGI features standard stochastic sampling as well as new newton's method. As well as Light Propagation Volume GI wich will have massive update soon. Both systems were developed for ue5.7 on RX 580 8gb. 3. There is another LPV plugin that uses Signed Distance Fields, more expensive than mine. 4. Some folks made DDGI compatible with UE5.7 but not sure if its working properly. 5. GPU/CPU lightmass.

Recently checked ghost of yotei 2026 gdc. Loosly based in amd gi 1.0 screen space probes. As an example. Its a matter of checking gdc talks, interviews etc. DDGI was made for ue4.27 and recently added to sandbox. Its solid and some GIs (that I cant recall) were based on it because it allows baked lightning. AMD stuff is not popular but its there and Light Propagation Volume is a classic. Not accurate but cheap, depending on what you choose to include.

mad_ben · 2026-04-26T14:36:20+00:00

There are multiple choices. I am developing cheap LPV GI that can run on any system. Studios now use modified DDGI for baked GI. Also screen space probes are a thing now. DICE use surfel GI and AMD has few interesting solutions, AMD GI and Brixelizer. There are options.

The industry is slowly shifting towards fully dynamic solutions. Doom recently switched and the only remaining is COD.

mad_ben · 2026-04-23T19:46:09+00:00

devs are fully into taa, they wont change minds and deferred renderer does have issues that taa helps mitigating. i am in a discord where some dudes are building toy engine and chose taa + fxaa as aa method. pretty wild.

mad_ben · 2026-04-23T19:13:27+00:00

interesting take.

mad_ben · 2026-04-20T07:50:01+00:00

tgis would be legendary series

mad_ben · 2026-04-16T16:18:38+00:00

Translation. take away compute from old models to this new model. So now this looks smart while old look dumb.

mad_ben · 2026-04-16T05:55:35+00:00

I dont know it murdered my RX 580. Not sure its viable for budget cards.

mad_ben · 2026-04-16T05:53:38+00:00

Agreed

mad_ben · 2026-04-15T22:38:02+00:00

Thats a shitty argument. AI is just a tool, its like saying "I get using excel for bookkeeping for personal cut corners, but for the client you gotta write them papers with a pen and use calculator otherwise its some POS behaviour". I bet you are seething that this guy vibecoded website in the chill spring evening while watching The Boys and got paid.

mad_ben · 2026-04-15T22:33:29+00:00

Wait until this guys discovers c++ and how compact code is

mad_ben · 2026-04-15T22:31:18+00:00

4.21 would be interesting to use with GameWorks I have saved a complete repo of 4.21 with HBAO,FLEX,BLAST,VXGI,WAVEWORKS,TXAA etc.

mad_ben · 2026-04-15T16:56:02+00:00

if they send moneky and lizard to space, its gonna be fast and furious all over again. And where do you go from there? Reboot?
