Pro Tip: If you use TAA or TSR you can annihilate the stepping effect with a Dither, you'll be able to keep your Max Steps to extremely low values while still looking good It's way better if you use a Blue Noise Dither too instead of the stock one The Steps can be optimized based on distance too from the camera, been suffering a lot in making this work since we're using POM on our Landscape, a lot of Optimizations and little tricks, especially in blending the different layers If you use PDO I'd suggest turning off Contact Shadows too, those are the ones that most of the times make it look all glitchy and stuff Wanted to share pictures of the setup but YT doesn't seem to like imgur links and removed my comments 2 times already So if anyone is interested in any of this, can maybe share the raw code

Bangin’ advice. I’ve used dithering with BumpOffset before to get a sort of ‘blurred vertical lines’ effect for an Ice shader before but didn’t think of using it in POM. That’s a good point about the distance optimisation - since the Custom node is actually doing loops based on the step amount input, changing it at runtime/based on a gradient would actually make it execute less code, unlike ‘hiding’ something with a Lerp.

@@IstyManame Just posted a video followup, production value is 0 tho, not very good at this and recorded all at 5-6 AM, probs set the video a 1.25x speed for sanity sake :p Making it came to mind this too: If you use POM you wanna make sure to use a lower resolution Texture for the Displacement since the resolution influences the amount of Samples, and you want to filter it Bi-Linearly instead of Anisotropically, this is one of the biggest performance improvements with it Some other fixes regarding velocity too included in it to make it all work

Please guys, consider not using TAA. TAA can easily give people motion sickness and many consider it to look really ugly. Many devs are using it to fake transparency, make cheaper AO, SSR, Global Illumination etc... but it comes at the cost of completely destroys motion clarity. I'm not saying that this technology isn't cool, but please be mindful not to over-use it. If someone disables TAA and many of your effects rely on it they will end up with ugly dithering everywhere and that's why many games (Especially UE games) have it forced on. This is where graphics settings come in handy

As others have noted, it would be good to understand the pros and cons of this, bump offset, and nanite displacement (at least when the later is feature complete).

do you have a vid on how you keep all that stuff in one texture image? ive been using 2 images per matereal but that's using the "NormalFromHeightmap" node but i think thats a realy slow way to do it

@PrismaticaDev Ай бұрын

I have the Normals in RG, Colourmask in B and Heightmap in A (or Alpha in A, for foliage etc) All my game is coloured using Vector Params instead of textures, and the Colourmask in B channel is just a greyscale that goes in to a Lerp between colours

@cwlogan13 Ай бұрын

@PrismaticaDev thanks for the response. Shame it takes 2 channels I'd still need another image for textures that need roughness and metallic I've been working with colour masks as well to be able to reuse textures easier although I didn't realise there was a 3 colour lerp like you used in this vid does it use 0,0.5,1 as 3 solid colour positions or do your textures have negative values and its using -1,0,1?

this video is so good, how would you think going around using parallax for a cubemap of a room inside a window for example? btw the bump way of doing it I really appreciate that you discuss it because I might use it in VR eventually as it is quite cheap

There is a built-in material function for fake interior rooms if I remember correctly. Also there are KZbin tutorials, maybe for UE4, but it doesn't matter in this case.

Is there anything that can be done to improve the rendering of non square textures with this? The effect stretches on the outer most pixels..

Nah, you just have to choose what better fits in your project, if you want to use all of it, then of course it will be expensive, it is high-end technology.

Currently working on an RTS game (top down camera with a 40-60% angle like Prismatica plugin demo)- 1) will POM fit great here? since the camera never going to a shallow angle near the floor this type of effect will probably never break 2) POM vs WPO- which one is better for performance?

@PrismaticaDev 6 ай бұрын

For a top down, BumpOffset might be enough. But POM with a low step count could also be fine. WPO would require a very dense mesh to get the same effect, but with Nanite tessellation it would be doable. I’d say the order of performance would be BumpOffset - WPO - POM

awesome. good note about nanite. there are some devices dont support it.
