Engine Shader Tutorial ?
Hi, I just purchased Engine Shader headers, is there any available tutorials around? I searched the forum but couldn't find any...

Thanks

Ok, I found through forum that Shaders Tutorials are available for engine sdk users, any chance to have them for Esenthel 2.0 users? at least for who bought the Headers.

Thanks

RE: Engine Shader Tutorial ?
Hi,

Currently creating shaders for 2.0 can be a little cumbersome, because for 2.0 I've planned to create an integrated shader editor (which is not yet available).

Therefore you'll need to manually copy some files from the attached package, and adjust the codes to set correct paths for:
-shader source - HLSL code (to the "Shader HLSL" folder from the package)
-shader destination - folder that points into your "{Project}/Game/Shader" folder

First to your project folder, copy one of the folders from the package, so you have:
"{Project}/Game/Shader/2/User"
"{Project}/Game/Shader/3/User"
"{Project}/Game/Shader/4/User"
"{Project}/Game/Shader/GL/User"


Attached File(s)
.rar  EE 2.0 Sample Shaders.rar (Size: 13 KB / Downloads: 77)

Thank you Esenthel I will start testing today. Also its great news to know that there will be shader editor for EE 2.0.

hi, where is this item in store? I dont find it, maybe it was only for EE1?
in EE2 I need to have source license to access the headers to compile the sample shaders you posted above?
(material_user_shader.enum.h)

from pdf:
"Using custom shaders is available only for licensed developers, if you're a licensed developer then please:
Download the Shader Archive available in the "EsenthelEngine Forum\Clients
Section\Source Codes"

licensed developers here meant owning binary or source license?

Hi Biga, I purchased it when I was using EE2.0, I think its also available for purchase to binary/source license members.

RE: Engine Shader Tutorial ?
thx. yeah seems here is organisational problem smile
our team leader bought 2 binary licenses but license can only related to user was logged in when paid.
so I appear as demo user and probably I dont see that item...

our team leader didnt see with binary license account.
maybe it needs source license?

Hi,

I've removed the shader headers from sale as separate items some time ago, they're now included only in the source version.
I've decided to do that because having the source version is currently the best way to customize your shaders.
In the future shaders for binary licensees will also be possible, but I'd need to redesign the shader system and make a shader editor for that (this will take time).

Thanks

RE: Engine Shader Tutorial ?
Sorry but limiting the shader headers to source licencees only sounds like a bad idea to me. I know that as a hobbyist i couldn't sub to the source only to gain shader access and shaders was an important aspect for me.
Luckily i managed to buy them before that.

Edit : Then again i understand that the shader system is not easy to use right now and will be much better in the future. Still no reason to take them out of the store.

RE: Engine Shader Tutorial ?
we have now the source license, but still cant build shader tutorials.

Code:
1>Source\Main.cpp(6): fatal error C1083: Cannot open include file: '../../../../../data/enum/material_user_shader.enum.h': No such file or directory

this file doesnt exist in source distribution...
nor the referenced one in tutorials: Data\Shader\Main.h

Hi,

That file was present in 1.0 package, but not in the later versions.
I've updated the RAR archive above to include it, and it's now present in the "Shader CPP" folder.

RE: Engine Shader Tutorial ?
thanks, now I built it successfully.
when I tried to run, it shows "Can't load engine.pak".
after commenting Paks.add("engine.pak"); line, this error disappeared.
now I get "Can't load shader Main" message at run.

what I did:

1. from the above rar, I unpacked the "Copy contents..." folder to my project folder - I assume they will be the empty folders for shader compilation
2. unpacked Shader HLSL to a folder
3. created a new application with the "01 - Shader creation.cpp", and replaced shader source folder in CompileShaders to what I used in 2.
4. Unpacked material_user_shader.enum.h to a specific folder and referred to it in #include
5. Build and run

Tried to debug in VS, the error popups before entering to CompileShaders.

AHA
commenting engine.pak was of course bad move, I uncommented and set a proper path for engine pak. now I'm getting shader compiler errors, but thats an advance already, so now I focus to them...

well seems for now I cant figure where is this EsenthelEngineShader folder what I have to update in main.h file...

RE: Engine Shader Tutorial ?
You follow the steps below.

Folder-File Structure.

C:\Projects\EsenthelEngineShader\(move the appropriate rar files here)
C:\Projects\Shader CPP\(move the appropriate rar files here)
C:\Projects\Shader HLSL\(move the appropriate rar files here)
C:\Projects\material_user_shader.enum.h

C:\ESENTHEL\Projects\(your project's folder e.x. !h4kif3gxoo270!s45ai7a1t)\Game\Shader\2\User
C:\ESENTHEL\Projects\(your project's folder)\Game\Shader\3\User
C:\ESENTHEL\Projects\(your project's folder)\Game\Shader\4\User
C:\ESENTHEL\Projects\(your project's folder)\Game\Shader\GL\User

Now in the Esenthel Code
Code:
/****************/
#include "stdafx.h"
#include "c:/Projects/material_user_shader.enum.h"
/****************/

void InitPre()
{      
   Paks.add("C:/Esenthel/Bin/engine.pak");
   DataPath("C:/Esenthel/Projects/(your project's folder)/Game/");
   ...
}

//In order to compile the shader code to the binary form.
void CompileShaders()
{
   if(D.shaderModel()==SM_GL)
   {
      ShaderCompile("C:/Projects/Shader HLSL/2D Shader.cpp", S+DataPath()+"Shader/GL/User/Custom Shader", SM_GL);
   }else
   if(D.shaderModel()>=SM_4)
   {
      ShaderCompile("C:/Projects/Shader HLSL/2D Shader.cpp", S+DataPath()+"Shader/4/User/Custom Shader", SM_4);
   }else
   {
      ShaderCompile("C:/Projects/Shader HLSL/2D Shader.cpp", S+DataPath()+"Shader/2/User/Custom Shader", SM_2);
      ShaderCompile("C:/Projects/Shader HLSL/2D Shader.cpp", S+DataPath()+"Shader/3/User/Custom Shader", SM_3);
   }
}

//This is how you call a shader technique and draw it on the screen.
void Draw()
{
   Shaders("User/Custom Shader").getTech("CustomTechnique").draw(null, null);
}

I hope i didn't forget anything. Let me know if you manage to do anything.
Also you can customize the sctructure to what you want later on but until you got something working stick to the one i wrote above.
