ats color map ULTRA shader [RELEASED]

Can you add an option to the script to allow the splatmap to be re-imported and updated, I know this can be done just by updating the generated material Control0 texture but it took me a while to find the splatmap as it isn't mentioned in the docs as far as I could see.

 

i will take taht into consideration

 

Is there a way to achieve color map from detail colors of layers like RTP?

Also it's not work with Unity 5.5 b3 anymore. here is the error.

 

you have to assign the color map painting tool. in its onspector you will find the button "create color map" which lets you create and save a color map generated form the details and splats.

5.5. is out of scope right now. and the error only affects the path blend shader, not the terrain shader.
you may try to make the shader work in 5.5. by editing lines 85 - 93 so they look like this:
// d.boxMax[0] = unity_SpecCube0_BoxMax;
// d.boxMin[0] = unity_SpecCube0_BoxMin;
// d.probePosition[0] = unity_SpecCube0_ProbePosition;
d.probeHDR[0] = unity_SpecCube0_HDR;

// d.boxMax[1] = unity_SpecCube1_BoxMax;
// d.boxMin[1] = unity_SpecCube1_BoxMin;
// d.probePosition[1] = unity_SpecCube1_ProbePosition;
d.probeHDR[1] = unity_SpecCube1_HDR;

but i haven't tested that...

 

Hi Lars,

I have everything set up fine, but the colormap painting tool isn't working properly for me. I have the brush size set at one, but the brush is enormous, and snaps to huge grid points (we have no grid tools running that might conflict either).

Is this a known issue? it makes painting the colormap impossible.

EDIT: Just worked out the issue... one of the artists had set the base texture resolution of the terrain to 16. Setting it to 2048 has fixed the issue.

 

no, it is not. it is assumed to just work fine...
do you have some more info for me?

 

Thanks, if we have 25 tiled terrains should we create 25 materials too? cause each material can contain 1 tessellation map.

 

yes, for now each terrain would need its own material.

 

I need some help, I'm trying to manually update the splatmap for the shader and I just can't work out how I get it to use my new splatmap. I thought I could update the control0 texture (posted above) but whatever I do it won't assign a new map and just ignores any splatmap I try to drag in. I must be missing some step but I just can't work it out.

 

I found a solution, I still have ats 2.5 and the splatmap apply in that works perfectly

 

there are also quite some scripts available which would do the job.
like this one from world machine:

Hi all,

I just bought it and when i combine 2 normals (tex1/text2) one of them become pinky (text1) and the combined texture looks like the main diffuse text1. And in game this gives an ugly result!
Do you know what could be the problem?

thanks in advance!

 

that sounds as if you were using version 2.5, right?
but to be honest: i have never heard of a problem like this before... if both texture assigned to the script are regular normal maps everything just should work fine.
maybe you can attach some screen shots from the editor?
lars

 

Many thanks for your prompt reply:
check below the 2first normals before i combine them

and here after combined:the result is just like the sand diffuse

 

By the way even changing the settings i still have a very shining bump effect, how can i get rid of it?
I'm using Unity 4.6.9
Maybe it's a noob question, sorry about that

 

Just a thought...i created the sand normal Inside unity......Maybe it comes from that?

 

it is not...
and your screen shoots looks absolutely disturbing:
it looks as if the script was changing the input textures!? just have a look at your 2nd screen shoot: input normal has changed!?
i have never encountered that problem nor have i heard about that before.
so there is not much i can say right now.
please check your texture namings: are normal and albedo names unique?
are normal texture set to be read/write enabled? they do not have to but that would make it easier for the script...

this is such a unique and weird problem that in case we can nor solve it fast i would recommend to simply combine the textures manually using photoshop, gimp or whatever software you have at your hand.

sorry about that.
lars

 

ah, may be... try to create it using xnormal, crazy bump or anything else as the script most likely uses the original asset (which is not a normal...)

 

I tried to rename the textures but no result! I will try making the normal outside Unity!
Can you tell me how to reduce the shiny effect ?


Thanks again for your very fast support!

 

unfortunately unity's new brdf tends to make everything pretty shiny...
lowering "shininess" to 0.0 may give you true lambert lighting though (only direct lighting).

 

You were right! I did the normal with GImp and it's good now!
Thank you very much.

Now i'm still fighting with the bump effect as i use a directionnal light with a custom script for daycycle!

 

Your shader is very impressive!
To reduce the shiny effect i lowered specular power and color!! Perfect!!!!
Tomorrow i'll get into Blending meshes on terrain!!!
Have a good night!

 

do not forget to leave a comment on the asset store

 

I guess night time doesn't do this excellent shader justice. More pictures coming soon...

 

wow!

 

That is awesome man!

 

Can't you just change this asset's name? It's not only colormap after all. It's great terrain shader like relief terrain pack. Not "Colormap Ultra Terrain Shader" but "Advanced Terrain Shader" maybe? (I know it's ATS)

 

i take that as a compliment, thanks

 

Awesome shader!

 

it getting better and better!

 

Hi There,

Currently stuck with an issue that the terrain remains completely black (editor and built app)

The only fix we found so far was to click on the terrain with the colormap script attached, this seems to activate the material somehow.

I thought this might be a unity bug, but the key is that it ONLY works when the ColorMapUltra component is expanded (and thus triggering OnInspectorGUI, only this fixes it for some reason)

Beyond this, it works like a charm.

Any thoughts?

 

which version of the cmu shader do you use? 2.5 or 3.0?
which version of unity do you use? dx11, dx9 opengl?

lars

 

Apologies for the lack of information

Build : Window X86
Unity : 5.4.2f2
CMU : 3.0
DX9 & DX11 (switching makes no difference)

Not sure if this matters but here are my terrain settings:
Size : 4000x4000
Height : 2000
Heightmap Resolution : 1025
Detail Resolution : 1024
Control Texture Resolution : 1024
Base Texture Resolution : 512

The Colormap settings are displayed bellow (perhaps you see something)

Only difference was expanding the component so that the editor triggers

Other Assets that (to my knowledge) could perhaps cause trouble
MapMagic

I am aware that unity 5 seems to have a black terrain bug, but I was unable to place the link between that issue and the fact that expanding your editor fixes it

 

my first guess: you have forgotten to save the created texture arrays – but only updated them in the editor!?
edit: your screenshoot of the cmu settings clearly shows that you have forgotten to safe the texture arrays as their slots only show up an icon – but no file name
use "Update Array" to get a quick preview in the editor. then always hit "Safe Array" too.


lars

 

Hi Lars,

Thank you for your response,

Unfortunately it was not that simple, here is a new screenshot, with the saved arrays and newly create and assigned material http://imgur.com/zg6fR6Z

 

how does the material itself look like?
just click on the assigned material in the cmu editor and make it show up in the inspector.

 

Hi Lars,

Here is a 4-pane screenshot with the material : http://imgur.com/ItyJ07h

 

hmm, your average colors look pretty strange (all grayscale?).
but that should not make the terrain show up in pure black.
so when exactly does it happen? if you enter play mode?
what happens if you drag the material to e.g. a simple sphere? is is black too?

 

The average colors are simply so it does not apply more color to a colored texture (the textures for grass for example are already green, adding a color here makes it multiply the colors)

As soon as the scene is loaded ,take note that there is no camera available directly afterwards, the camera is loaded around 10 seconds later (after the loading screen), same goes for a built version and for the editor

I tested a sphere, and indeed it shows the same behavior (good one by the way, did not think of testing it this way).

I'll mess around with more settings tomorrow, if i find something i'll let you know what it ended up being.

 

Hey Lars,

Am playing with your latest, and added snow to my terrain.. but its giving me weirdness.. do you have any suggestions ?



I started with a standard unity terrain.

Cheers,
Adam.

 

Really like the height-based splat blending! Works great even on my 4x4km test terrain with 2048 Control Texture resolution

 

hi adam,
do you mean the "dark snow" on top of the maintains?
have you added the Lux dynamic weather script and added a proper snow texture?
that would be my first guess.
otherwise you might go through alebedo, normal specular and smoothness to find what is wrong.
maybe a normal?

 

Hi @larsbertram1,

I'm considering purchasing this asset to help optimize my terrain in an open-world PS VR project. I've very close to a solid 90fps and the alpha blending between textures on Unity's standard terrain shader drops my framerate by about 10 frames when heavily blended areas take up a large portion of the screen (i.e. looking directly at the ground).

A few questions for you:

• In what ways is this shader more performant than the built-in Unity terrain shader? I don't really know much about either shader.
• Can this shader be used with Unity's standard Terrain system? Or do I need to use my own static terrain meshes?
• Will this shader work with single-pass stereo? I don't see why it wouldn't, but I thought I'd ask.

Thanks so much!
Nick

 

hmm, it offers a lot more possibilities... so v3.0. is not faster but much nicer.

yes.

i have never tested this, sorry.

 

I suppose this was asked dozen of times, but without thread search feature in the forum I can't find the answer: it's tested working with TerrainComposer 2? I suppose yes since this generate standard terrains, but.

 

i haven't done that. but i suppose it should work.
i do not think that terrain composer supports using the shader while creating the terrain (as it would have to constantly update the texture arrays etc.) but you can use a standard built in shader while creating and texturing the terrain and then finally switch to cmu.

 

You are pro man...It works for me..Thanks

 

In Unity 5.5 release version also, there are some problem with shaders:
Here is the solution: Just replace
//d.boxMax[0]=unity_SpecCube0_BoxMax;
//d.boxMin[0]=unity_SpecCube0_BoxMin;
//d.probePosition[0]=unity_SpecCube0_ProbePosition;
//d.probeHDR[0]=unity_SpecCube0_HDR;
d.probeHDR[0] = unity_SpecCube0_HDR;
d.probeHDR[1] = unity_SpecCube1_HDR;
//d.boxMax[1]=unity_SpecCube1_BoxMax;
//d.boxMin[1]=unity_SpecCube1_BoxMin;
//d.probePosition[1]=unity_SpecCube1_ProbePosition;
//d.probeHDR[1]=unity_SpecCube1_HDR;

 

Just bought it and I can't figure out why everything speculates so much. Demo scenes work fine and all the settings are the same, yet it is very shiny. Tried to toggle everything to no avail. Can someone help me?

 

hmm – a lot of people compialn about unity's new ggx based brdf, which makes things much more shiny.
but that looks very shiny.
i would recommend to go through the different deferred preview modes in the scene view like smoothness and specular to see how your gbuffers look like.
