Fabio Policarpo - Relief Mapping with Correct Silhouettes

Hi all,
I am impressed and I have some questions to ask on the shader
I tested the texture_863.zip with relaxed_cone_relief_mapping_112.shader but do not see the shadows effect.
if I put a light in the scene does not reflect over the object and the shadows do not appear.
See example:



There is a method to see shadows?
Is possible to react to light the scene the object created with this shader?
I'd like to use this shader, but it does not react to the external lights of the stage and if it does not create shadows remains an unusable product.
Could someone help me understand?

 

nobody help me?

 

Those shaders are written that way. Light doesnt effect them... someone would have to modify them for you in order to react with lights in the scene.

 

How do you get the silhouette working? I've got an image similar to his first image, except that mine doesn't have the bumpy edges.

 

Welcome on page of non-responses with me!

 

Finally got around to taking a look at the updated one. No go on 3.2 or I imagine 3.3, fails to compile on both Pro and Indie, PC and Mac

 

Yes, 3.3 is giving me some odd errors with a lot of my shaders. I'll look at it when I get some time.

 

Ok, here is the fixed relief shader for version 3.3:

YAY! *runs off to try it*

Oh wow that looks awesome! :O Those guys further up the thread are gonna die if they don't spot this thread now, lol. Awesome work man, awesome indeed!

Works fine with shadows, lightmaps, the lot, more awesome haha.


A weird thing happened though, when I first imported it and tried it, half of anything it was used on would appear invisible. I fiddled with it, trying to get it working right, had some success but then gave up as I don't know what I'm doing and reverted back to the original version, and suddenly it works perfectly fine. Weird, lol.

Edit: Ignore that last bit about the weird thing, the problem was between the chair and the computer. Just realized it only does it if you change the texture to anything other than x1, y1. My bad!

 

It has got some problems yet IMHO.
Also, quite useless without shadows implemented.

 

This shader is great, truly proper amazing. But it's not silhouette-correct like the others, is it?

Thanks for making this.

 

Would it be possible to add a fresnel effect to this shader?

 

Possible? Sure, but keep in mind they still cannot be modified to work with Unity's shadow system.

 

Good to know. Now I just wish I had the knowledge to do it. I'm working with cellular models and I don't want shadows, so a solution with fresnel would be awesome.

BTW, I don't know if I mentioned it, but I found that the xNormal relief map works pretty well and computes much faster than the preprocess executable.

 

You would have to modify the depth map before Unity processes it, to include the new silhouettes from the relief mapped objects. Of course, I could write a custom shadow solution to output my own depth map, but really would be great if we could tie it into Unity's.
If you know a way to access the depth buffer before it's processed for shadows, please let me know and I will happily stand corrected!

 

why is this??

 

Its a common issue. You set the alpha to 1, if the calculated uv's are not in the 0 - 1 range. As far as i know, theres no easy way to change it.

 

what do you mean?
so how can I fix it,and what caused this problem?

 

Thats the point, you can't fix it. Simply don't use alpha, to avoid it.

 

thanks a lot,
its solved.

 

Thank you Reissgrant for your conversion. I'm trying to get the first post result with it but I dont succeed. There is no occlusion. The result is like a parallax mapping and not a relief mapping. Could you help me.

 

It seems to be great, but I have an error, trying to use it:

Anyone have the project FXComposer and depth textures used in the Relief Mapping of Non-Height-Field Surface Details? The author's link is broken for sources and I do not know how to generate those textures, rings depths or the dog depths represented in the paper.

Thanks

 

Does this shader actually work with silhouettes? It doesn't look like it to me... just wondering if I'm doing something wrong with the textures...

 

The shader does not work with silhouettes, as you need to modify the depth map for that and it's currently not possible, from what I understand.

 

Reissgrant; I love this shader. As Frank Oz alluded to earlier, it doesn't appear that the textures can be tiled. Is that an inherent impossibility, or could that be programmed into the shader?

Edit: NEVERMIND -- I just found the "tile factor" slider.

 

Hi

The shader "relief_correct_silhouettes_181.shader" is producing errors in Unity 3.5.2.
Is it our maloperation, or a known problem?
We put the shader within a folder named "shader" into the asset folder.

Thanks for a short feedback

 

So what is the best practice for laying out UVs for this sort of shader to avoid problems?

 

can you share the shader in unity 3.5 or hight?
