If you want multiple POM layers, you need to do the parallax for each layer using its own heightmap. Technically even the alpha needs to have parallax to be correct but it is impossible to do that for landscape layers. In general as long as the base alpha is somewhat blurry that part should not be noticeable.

The custom nodes on the left are simple "SampleGrad" nodes that fix some bad mips from sampling with parallax UVs.

The code for that node is:

Code:

return Tex.SampleGrad(TexSampler,UV,InDDX,InDDY)

So I have the shader working without silhouette, but when I apply it to terrain it totally flips out.
Similarly, if I apply it to an object that has uv coordinates pelted, it crashes the editor or may even crash the machine.

Is there any place that discusses the different rendering constraints for decals and terrain? When I apply my parallax shader to terrain it goes crazy.

I was able to put a POM material on terrain with no issue. Are you using UVs or WorldCoords for the UV input? If you are using UVs most likely what is happening is the landscape coords are not in alignment with the worldposition axes... try swapping to UVs instead of worldposition or try rotating your terrain 90 degrees.

The issue with pelt mapping is strange. I have no idea what might cause that. I have tested on a variety of meshes and never seen different behavior on different meshes. If you can send me the mesh (just upload it somewhere) I can try to reproduce it.

I don't seem to get it to work properly in 4.9Pre. Anyone has maybe an example Material?

*edit* I dont really see the point in t3d since you still have to copy the text from the t3d file. There is no import t3d ability from the content browser that I can see.
Try this I guess. You probably want to do the matfunction first but even so it probably will have to be reconnected to all the pins.

Where do I have to paste it?

**Traggey** · 08-11-2015, 07:59 AM

Yo, anyone got this working on 4.8 and up? I'm running 8.3 and copy pasting the MatFunc code into a materialfunction results in an engine crash, the pure material code refuses to be copy pasted into the material at all.

**Daedalus51** · 08-11-2015, 01:13 PM

Hey Ryan,

I modified the MatLayerBlend_Standard to also pass the pixel depth so I could make two material functions...one with rock and one with soil/earth, both using parallax occlusion for a Landscape Material. Without pixel depth...its not really usable since everything appears to be floating.

So when I just use that and choose material attribute only input in the material, pixel depth should get past, but its not visible. When I however switch back to standard material pin mode and break after the material layer blend to connect pixel depth, I get a crash that says:

"Fatal error: [File

:\BuildFarm\buildmachine_++depot+UE4-Releases+4.8\Engine\Source\Runtime\Engine\Private\Materials\MaterialShared.cpp] [Line: 2171]
We should never need the IO index of the MaterialAttriubtes property.
"
So material function blending is not possible right now. When I connect just one of the functions output of pixel depth manually, it works just fine.

Is this something you guys are aware of? (btw...I am using 4.8.3)

Besides that, great work on the node! Loving it so far

Cheers!

I just recreated that setup and was unable to get that crash. So hopefully that means it is fixed already in code.

I am not exactly sure how you are using pixel depth offset to fix the floating blend. That may just make both layers have pixel depth offset that is correct in-and-of-themselves, but I can't see it fixing the floating blend. But I am interested to hear your solution since I have been thinking of making a separate version of the POM node that is intended to work with multiple layers.

The method that I thought of to make this work nicely involves passing a 'mask' texture object input into the POM node but it would involve a double-texture lookup at every loop iteration and wouldn't easily work on landscape since you cannot sample the blending mask at offset locations.

Ryan, could you tell me how your POM compares to the displacement shader CryEngine uses (pixel accurate displacement mapping)? Of course only if you can and want to.

It's nice to see some more advanced features coming, since it looks like UE4 is "leaving" out a few in comparison to CE3 (I still think the best choice I made so far was to switch to UE4

), but I'm not sure if that's really the case, it might be just my impression. (One example out of my head would be volumetric fog, which Crytek recently implemented)

As far as I know, PADM uses mesh curvature to bend the ray as it passes through the surface. I am not sure how they come up with the curvature map. I am guessing it is done in code under the hood and pre-baked to UVs. If I can ever get to the point where I have this clean curvature data pre-baked in a way like that, it will be fairly easy to do.

In fact I have already been prototyping it in a purely dynamic way, but the math is incomplete. I was able to use DDX/DDY to estimate mesh curvature, but it treats curvature in all direction equally. If you were you look 'down the barrel' of this cylinder, it would appear to vanish as if it curved like a sphere. The only reason it doesn't look so bad in the example below is that I also used fresnel as a curvature mask which isn't really correct, more of hack.

When I try to actually solve the curvature as a proper Normal Curvature, facets appear which make the effect have seams at the polygon borders. So I will instead need to find a way to pre-compute the curvature maps. Ideally it would be the type of thing where you just right click in the content browser and select "Bake Curvature map to UV 3 and 4" or something, so you do not have to use an external program.

Without curvature estimate (assumption is that the heightfield is locally planar)

And to be honest solving the proper normal curvature gets really confusing since it involves these crazy Tensor Matrices. The not-so-basic idea is explained here:

There is an alternate way of handling it as well. Basically instead of bre-baked curvature data, you bake out a tangent map texture. Then you pass the tangent map as an object reference to the POM, and it has to look up that second texture sample at every loop iteration. While this version is basically trivial for me to implement, the cost is going to be *way* higher than the above approach, and it requires a separate texture for every mesh so it would never be as plug and play. I am not sure which version crytek uses. It may be possible to render these tangent maps using a build process automatically, but that seems like an unlikely solution since it would require touching a lot of code to do a very narrow effect that is doable in more elegant ways.

The idea with the first approach is to precompute curvature, then once (outside of the loop), solve the problem "How much does this ray escape the surface with a Z offset at every step". So you only pass a single new scalar into the loop once you know how much the ray curves along the surface curvature.

Thank you so much Ryan for this detailed explanation! Also thanks for putting so much work and effort into our requests.

(I'm still trying to comprehend all the information you gave in your post, so I don't really know what to say/add now)

Hey Ryan,

thanks for your reply. I will try to explain better what I did and whats is not working.

So first of all I have a material function for rock and one for soil/forestground. Both functions use the pom and output pixel depth offset from your pom node into the according pin in "make material attributes"
I then added another lerp node inside of a copy of MaterialLayerBlend_Standard and hooked up pixel depth there as well.

So what I want in the end is basically this behavior for both layers in my material (and even more than these two in the end:

I made my material like this:

But then it only looks like this:

so for some reason, even though I pass the lerped pixel depth values from the two functions via the material attributes, it seems they are ignored in the end.

When I hook it up like this, it works for that one function that I use of course:

So thats basically what I am trying to do. I havent yet even touched the look of the blending of the layers with pixel depth since I never got that far

Hope this helps a bit more to reproduce the issue!

Thanks and cheers!

EDIT: I dont know what your take on this is, but I initially wanted to use tessellation for all this landscape material stuff, but even with a distance fade on the multiplier, results are super slow and not very clean cause of limited landscape base resolution.

**RyanB** · 08-11-2015, 04:20 PM

There was a bug where certain shader states caused a PDO crash. To test if you still have that same crash, try hooking up a constant '0' to PDO. If that crashes, then most likely the fix that fixed that also fixed the problem you are seeing.

Your material setup seems sound.

Looks like you were talking about a different floating issue. As long as both separate POM materials exist in very similar height ranges, the floating should not be that bad. I still need to think of a solution that actually works nicely on landscape.

Yes, tessellation is absurdly slow on landscape even if you set the factor to 0. I talked to our rendering guys and apparently the implementation is very naive with lots of room for improvement. Sadly I am not sure when it will be worked on.

Hey Ryan,

thanks a lot! I will try that out later. Regarding tessellation, thats still good to hear!

I read a couple of papers about frostbite and how they do landscape stuff, and I always wondered, how can they pull off all this, even on consoles (Dragon Age and Battlefront have some sweet stuff going on!^^)

So yeah....its very great to hear that indeed there is quite some room for improvements!

Thanks again and cheers!
