How to use parallax?

[Wild Cat]

Good evening!

 

I have a little problem. Our artist have made a building. I tried to set up parallax shader in some materials. But I could see parallax effect only in material editor. Screenshots from editor and material editor is here:

Everything appears correct, but I recommend using POM instead of plain parallax. It is quite a lot more obvious of an effect.

Hi !

 

I had the same problem. The parallax effect is not obvious to use because we must not forget to put a alpha layer in your texture ...

 

If you use the POM.FRAG, the default settings in the MESH.FRAG do not get the correct effect.

 

I have implemented it in the next release of ADN, which makes it easier to configure, it will come out in a few days

1) I have made an alpha channel to all textures. Compression is dxt5. Nothing changed.

 

2) In ADN I have an error:

 

 

3) Tommorow I'll try to use POM.FRAG.

 

P.S. If anybody wants, I could upload a material file with textures.

[Josh]

Please post your texture and material files.

2) In ADN I have an error:

 

 

 

That is not an ADN error. You are using a version of ADN that doesn't have the parallax option built in... try downloading the one that was released today.

Use this material:

texture0="abstract::ceramics_02.dds"

texture1="abstract::ceramics_02_nrm.dds"

shader="abstract::mesh_diffuse_bumpmap_parallax.vert","abstract::mesh_diffuse_bumpmap_parallax.frag"

 

The heightmap should be packed into the alpha channel of the diffuse texture. This eliminates one texture lookup, which will make it faster.

Do you even have a license, Wild Cat? Seems kind of odd to "white out" your directory structure in your screen-shots, lol.

[Icare]

I found why your parallax effect doesn't work, your alpha channel on diffuse is completely white texture like said Josh

 

APHA channel of the diffuse texture mustrepresent your image. You can get something not too badly with :

- get the negative off diffuse

- increase her brightness

- glue the result in your alpha channel

 

 

You use an older version of ADN that not support Parallax, go to the main post and download the 1.1. After you must select the material type on PARALLAX not DIFFUSE

This my result, if you put your heightmap in the alpha channel of you diffuse.

 

[Wild Cat]

Use this material:

texture0="abstract::ceramics_02.dds"

texture1="abstract::ceramics_02_nrm.dds"

shader="abstract::mesh_diffuse_bumpmap_parallax.vert","abstract::mesh_diffuse_bumpmap_parallax.frag"

 

The heightmap should be packed into the alpha channel of the diffuse texture. This eliminates one texture lookup, which will make it faster.

 

I did it. In Material Editor nothing changes. In model viewer too. For packing i'm using DirectX Texture Tool, is it okay?

 

But why I could not see any shader effect in editor or model viewer?

 

P.S. Also, I tried using shader="abstract::mesh_diffuse_bumpmap_parallax.vert","abstract::mesh_diffuse_bumpmap_specular_pom.frag".

 

P.P.S. I think, something wrong is with light, or model. Soon I'll try another model.

[Icare]

It's working fine if you do the right things.

 

Look at my screen shot....

[Josh]

Sorry, the frag shader should actually be "mesh_diffuse_bumpmap_specular_pom.frag".

 

Parallax occlusion mapping (POM) is the raised effect I think you want. Plain parallax mapping is just sort of an enhanced bumpmap. I honestly don't even remember exactly what it does, and it should probably be removed.

Have you sent your information to Josh so he can get you into the forum as a developer?

I'm not a developer.

[macklebee]

thats strange... considering that it appears that you have 2.4?

[Wild Cat]

Strange things happens. Sometimes.

[macklebee]

uh-huh... thats what i thought...

[Paul Thomas]

Yeah, figured it was an odd thing to do to block out your directory path, attempting to hide "2.4" lol. Failure.
