[Highpass filter?]

I did a high-pass filter:

 

 

VERTEX:

 

#version 400

uniform mat4 projectionmatrix;
uniform mat4 drawmatrix;
uniform vec2 offset;
uniform vec2 position[4];

in vec3 vertex_position;

void main(void)
{
    gl_Position = projectionmatrix * (drawmatrix * vec4(position[gl_VertexID]+offset, 0.0, 1.0));
}

 

FRAGMENT:

 

 

//from https://learnopengl.com/Advanced-OpenGL/Framebuffers

#version 400

//Variables
float pass_mix = 0.5;
float spread = 1000.0;
float brightness = 1.3;

//Uniforms
uniform sampler2D texture1;
uniform bool isbackbuffer;
uniform vec2 buffersize;

//Outputs
out vec4 fragData0;

float offset = 1.0 / spread;  

vec3 blendMultiply(vec3 base, vec3 blend) {
    return base*blend;
}

vec3 blendMultiply(vec3 base, vec3 blend, float opacity) {
    return (blendMultiply(base, blend) * opacity + base * (1.0 - opacity));
}

void main(void)
{
    vec2 coord = vec2(gl_FragCoord.xy/buffersize);
    if (isbackbuffer) coord.y = 1.0 - coord.y;
    
    vec4 outcol = texture(texture1,coord);

    vec2 offsets[9] = vec2[](
        vec2(-offset,  offset), // top-left
        vec2( 0.0f,    offset), // top-center
        vec2( offset,  offset), // top-right
        vec2(-offset,  0.0f),   // center-left
        vec2( 0.0f,    0.0f),   // center-center
        vec2( offset,  0.0f),   // center-right
        vec2(-offset, -offset), // bottom-left
        vec2( 0.0f,   -offset), // bottom-center
        vec2( offset, -offset)  // bottom-right    
    );
    
    //Blur
    float kernel[9] = float[](
        1.0 / 16, 2.0 / 16, 1.0 / 16,
        2.0 / 16, 4.0 / 16, 2.0 / 16,
        1.0 / 16, 2.0 / 16, 1.0 / 16  
    );
    
    vec3 sampleTex[9];
    for(int i = 0; i < 9; i++)
    {
        sampleTex[i] = vec3(texture(texture1, coord + offsets[i]));
    }
    vec3 col = vec3(0.0);
    for(int i = 0; i < 9; i++)
        col += sampleTex[i] * kernel[i];
        
    //High Pass
    vec3 high_pass = 0.5 - 8.0 * (col - outcol.xyz);

    //Output
    fragData0.xyz = blendMultiply(outcol.xyz,high_pass,0.5);
    //fragData0 = vec4(high_pass,1); //pure high pass
}

 

 

 

[Dissolve shader problem]

You can try changing the bottom of the shader like this. This works in the material editor for me.

 

#if BFN_ENABLED==1
    //Best-fit normals
    fragData1 = texture(texture15,normalize(vec3(normal.x,-normal.y,normal.z)));
    fragData1.a = fragData0.a;
#else
    //Low-res normals
    fragData1 = vec4(normalize(normal)*0.5+0.5,fragData0.a);
#endif
    int materialflags=1;
    if (ex_selectionstate>0.0) materialflags += 2;
    fragData1.a = materialflags/255.0;

 

    float specular = color_specular.r * 0.299 + color_specular.g * 0.587 + color_specular.b * 0.114;

    fragData2 = vec4(0.0,0.0,0.0,specular);

    vec3 dissolve_col = vec3(0,1,0);
    if (NoiseV<InvAlpha+0.03) fragData2 = vec4(dissolve_col,specular);

}

 

[Dissolve shader problem]

I'm snowed in I have limited power/internet. I'll get back to you on it but it looks like the specular affects it because he made the specular channel and the normals alpha channel the same. I tend to think Shadmar knows what he's doing and I'm not sure why he did it this way but I'm sure the fix will be pretty easy.

[Dissolve shader problem]

Is it red in the Material Editor? If so it could be your normals alpha channel.

Edit: I just saw the picture it looks like it is. The first thing I would do is check your fragData1 lines in the Fragment shader. They should look like:

    //Normals Output
    fragData1 = vec4(normalize(normal)*0.5+0.5,fragData0.a);
    fragData1.a = 1/255.0;

[Shader woes]

Oh that one looks cooler anyway.

[Shader woes]

This works fine for me. Is the shader compiling? Or do you mean you get some kind of lag?

Awesome. Thanks, guys.

[Anyone have Aggror's old FlowGui ?]

I used to have it I can't find it anywhere

[Introduction to Ultra Engine API]

Awesome, dude. It's only going to get better from there. I love that you can put materials on terrain.

[Strategy]

Sounds great, man. Congrats. I still don't like the subscription thing though. That's my only gripe. Everything else A+.

[planar reflection won't stay put]

Awesome. Thanks, man. I'll see what I can do with this.

If you want you can send me a sample project and I can look into it.

Yeah that'd be great.

Those lines look like you are doing a texture lookup with texcoords outside the 0-1 range on a clamped texture.

I don't have anything clamped. I did try clamping stuff but nothing seemed to affect it.

How do you create the reflection texture? And how do you assign it? I am very sure that this will not work from within the editor as the scripts are not updated (except postprocessing).

Just using the shader from above.  That's why I'm wondering if I need to use a script like a Render function or something. It does look like that in game too. The one I was using has a similar problem it looks ok until I look down then I get this. I dont' know what it is but it looks like maybe it has to do with the buffer not fitting to the screen?

[planar reflection won't stay put]

All I get with that are these weird lines. I'm not sure what they are. Like the buffer or something? Even on the one I was using I was getting a similar thing.  Do you know what it is ? What's happening here?

 

 

[planar reflection won't stay put]

This is what I have:

VERTEX:

void main()
{
    //entity matrix
    mat4 entitymatrix = entity.matrix[gl_InstanceID];
    mat4 entitymatrix_ = entitymatrix;
    entitymatrix_[0][3]=0.0;
    entitymatrix_[1][3]=0.0;
    entitymatrix_[2][3]=0.0;
    entitymatrix_[3][3]=1.0;
    
    //model position
    ex_vertexposition = entitymatrix_ * vec4(vertex_position,1);
    gl_Position = projectioncameramatrix * ex_vertexposition;

    //clip
    float cam = cameraposition.y;
    float c = 2 * (cam - ex_vertexposition.y);    
    vec4 e = ex_vertexposition;
    e.y += c;
    clipspace = projectioncameramatrix * e;

    //normals
    mat3 nmat = mat3(entitymatrix_);
    ex_normal = normalize(nmat * vertex_normal);
    ex_binormal = normalize(nmat * vertex_binormal);    
    ex_tangent = normalize(nmat * vertex_tangent);

    ex_texcoords0 = vertex_texcoords0;
}

 

FRAGMENT:

 

void main()
{

    //Normal
    vec3 normal = ex_normal;
    normal = normalize(texture(texture1,ex_texcoords0).xyz * 2.0 - 1.0);
    normal = ex_tangent * normal.x + ex_binormal * normal.y + ex_normal * normal.z;    
    normal = normalize(normal);

    vec4 clip = clipspace;
    clip.xyz *= vec3(1,-1,1);
    clip.x = (clip.x / clip.w) * 0.5 + 0.5;
    clip.y = (clip.y / clip.w) * 0.5 + 0.5;

    //Reflection
    vec4 reflection = texture(texture10,clip.xy)*0.8;

    //Diffuse Output
    fragData0 = reflection;
}

 

 

[planar reflection won't stay put]

I was trying to make my own. So far I'm just using a shader. I'm basically just flipping the Y texcoord on the model so the image is flipped. But I can't seem to figure out how to make it move the opposite direction when I "yes" nod the camera.

[planar reflection won't stay put]

Would I need to use a script for this or can it be done entirely in the shader?

[fog question]

Yeah this works. With this all you need to do is make a pivot, attach the script, and drag the player/camera into the script slot. The closer you get to the pivot the thicker the fog gets.

 

fog zone.zip

[fog question]

This is an interesting idea. I'm thinking maybe somehow use a PostEffect fog then thin it out or thicken it based on the distance of the cameraposition to the "center" of it. I'm going to try this. Something like:

output = mix(regular screen, foggy screen, distance(cameraposition , self.entity:GetPosition())))

[Simple Vehicle function]

I'm not that good at scripting but I think maybe put the self.Updatecamera() line in the UpdatePhysics() function? I think the Start() function would only update the camera once at the beginning and that's all. You want it to keep updating. Something like that

[Question about an Acknowledgments Map i want develop...]

Yeah man that's awesome. I'm glad you like them . I don't mind if you put me in there somewhere.

[Regarding vegetation billboarding]

If the problem's in the shader I can probably figure it out. If you get stuck you can send it to me and I'll fiddle with it. But my best guess - assuming it's not a bug, is that either the shader is not compiling or maybe you made a change and forgot to hit save somewhere so the changes didn't update.

[Regarding vegetation billboarding]

Looks like maybe the shader isn't compiling?

[planar reflection won't stay put]

Hey Josh how did you get the planar reflections to stop following the camera on the water? Seems like no matter what I do if I nod the cam "yes" the reflection wont' stay put. This is what I have. I'm stuck here:


vec2 coord = gl_FragCoord.xy/buffersize;

if (isbackbuffer) coord.y = 1-coord.y;

vec4 reflectcol = texture(texture10,coord);

fragData0 = reflectcol;
