Hi guys! I found a bug (as I suppose) in j3m Material.
When I assign g_time in j3m, so animation does not work.
But when I assign the g_time in my code, so it works.
[java]mat.setFloat(“g_Time”, 1.0f);[/java]

Another bug with j3m:
I did some modifications for toon shader here: http://hub.jmonkeyengine.org/groups/free-announcements/forum/topic/mikumikudance-viewer/?topic_page=4&num=15
When I did that below, it worked ok:
[java]vec4 colour;
vec3 N = normalize(normal);
vec3 V = normalize(vViewDir.xyz);
if (dot(N, V) < 0.2) colour = vec4(0,0.5,0,1);
else colour = (((AmbientSum + DiffuseSum) * diffuseColor) +
SpecularSum2 * specularColor * light.y * 0.8) ;
gl_FragColor = colour;[/java]
Uploaded with ImageShack.us
But When I use EdgeSize unform (with any values (0.2, 0, 5, -100, xxx…)) in j3m Material, so I got such green edges:
[java]vec4 colour;
vec3 N = normalize(normal);
vec3 V = normalize(vViewDir.xyz);
if (dot(N, V) < EdgeSize) colour = vec4(0,0.5,0,1);
else colour = (((AmbientSum + DiffuseSum) * diffuseColor) +
SpecularSum2 * specularColor * light.y * 0.8) ;
gl_FragColor = colour;[/java]

My log with j3m and EdgeSize uniform:

You may be misusing g_Time as that is supposed to be set by the engine, not your code.
Time needs to be listed in the WorldParameters and the shader needs to have a g_Time uniform that it uses… but you should not have to set this from your own code.
I use this for the waving of Mythruna grass, so I know it works in principle. I can’t say why it is doing inconsistent strange things in your case but since you are doing something you shouldn’t, it could just be that when you set g_Time in code that the engine overrides it where it doesn’t get a chance when it’s part of the j3m. But I’m just speculating.
For the second issue, if you set your uniform using mat.setFloaf(“EdgeSize”,values); the uniform should be named m_EdgeSize in the shader.
@pspeed : I did it in WorldParameters and has g_Time.
Thi is my matdef:
MaterialDef FakeParticleBlow {
MaterialParameters {
Texture2D MaskMap
Texture2D AniTexMap
Float g_Time
Color BaseColor
Boolean Animation_Y
Boolean Animation_X
Boolean Change_Direction
}
Technique {
VertexShader GLSL100: Shaders/FakeParticleBlow.vert
FragmentShader GLSL100: Shaders/FakeParticleBlow.frag
WorldParameters {
WorldViewProjectionMatrix
Time
}
Defines {
ANY_DIR_Y : Animation_Y
ANY_DIR_X : Animation_X
CHANGE_DIR : Change_Direction
}
}
Technique FixedFunc {
}
}
You’ve masked the real value with a uniform. Take it out.
Edit: ie: the MaterialParameters Float g_Time should be removed.
@pspeed: Thanks for reply! g_Time is speed of animation parameter. If I remove it, so I will not be able to change speed animation. This parameter is vital, and it works inside of code. And you can see haw this shader works on that video: http://hub.jmonkeyengine.org/groups/contribution-depot-jme3/forum/topic/fakeparticleblow-shader/
@nehon: Thanks for answer. Do you mean I should use “m_” parameter for uniforms? I thought it was a deprecated parameter. 
Well, I’ll try to make all my uniforms with “m_” and post here the result.
@pspeed: At that topic nehon recommended me to use g_Time: http://hub.jmonkeyengine.org/groups/graphics/forum/topic/how-to-animate-textures-in-jme3/ So I think g_Time should be used.
g_Time is set by the engine. You should never directly set anything starting with g_. I think @nehon was mistaken.
I use g_Time to animate my grass… and it varies with the system timer. I never actually set it. If I want to animate faster then I scale it in my shader.
Hmmm… unless he was recommending that you set it every frame to something faster than system time. Just setting it once really “shouldn’t” have any effect though it might as a side-effect of something else going wrong.

He means that in the .vert and .frag files it is m_Foo. When you set it in code or in the material file it is just Foo. The engine prepends the m_ for you. m_ indicates (in the shader) a uniform set by code. g_ indicates a uniform set by the engine.
So I just read the linked thread and I think you misunderstood the content. I didn’t see a post where it was suggested that you set g_Time yourself… only that you can use it in a shader because the engine is setting the global value for you.
I’ll reiterate that you will have undefined and potentially bad/non-functioning behavior if you declare these g_ uniforms and set them yourself. Let the engine set them.
Oh, Thanks!!! I will try to experiment with “m_” and “g_” parameters!!! Thanks!!!
Nehon said in that topic about g_tpf and g_time:
Actually you can in JME3.
there is a g_Tpf ot g_Time uniform passed to the shader if you declare it in the worldParameters section of the j3md file
Ok, but how can I change speed of animation? g_tpf makes it faster or slower depending of its value. I saw direcX shader which used Time parameter too in the same way…
Is this your shader? g_Time moves at the speed of system time. If you want to move it faster then multiply it by some value inside the shader… ie: where it is used.
Something like: [java]g_Time *= m_Value;[/java] ???
I shy away from modifying uniform values directly in the shader. Paranoia about the bad things that happen if you do the same to vertex attributes.
…but presumably you are using g_Time somewhere and that is where I’d multiply it by your m_Value.
So, essentially, yes. Sort of.
Hi guys again!!!
About EdgeSize bug - it was my mistake. I did not use “m_” parameter in my fragment shader, so it worked incorrectly.
About g_Time bug - I changed g_Time to m_TimeSpeed parameter, but the bug presents. It perfectly works in my code, but it does not work in j3m Material. Looks like texture is not updated in j3m (with SimpleUpdate ()), or Tpf does not work in j3m.
My Code:
Vertex Shader:
[java]uniform mat4 g_WorldViewProjectionMatrix;
uniform float g_Time;
#if defined (ANY_DIR_Y) || defined (ANY_DIR_X)
uniform float m_TimeSpeed;
#endif
attribute vec3 inPosition;
attribute vec2 inTexCoord;
varying vec2 texCoord;
varying vec2 texCoordAni;
void main(){
gl_Position = g_WorldViewProjectionMatrix * vec4(inPosition, 1.0);
g_Time *= m_TimeSpeed;
texCoord = inTexCoord;
texCoordAni = inTexCoord;
#if defined (ANY_DIR_Y) && !defined (CHANGE_DIR)
texCoordAni.y += g_Time;
#elif defined (ANY_DIR_Y) && defined (CHANGE_DIR)
texCoordAni.y -= g_Time;
#endif
#if defined (ANY_DIR_X) && !defined (CHANGE_DIR)
texCoordAni.x += g_Time;
#elif defined (ANY_DIR_X) && defined (CHANGE_DIR)
texCoordAni.x -= g_Time;
#endif
}[/java]
Fragment Shader:
[java]varying vec2 texCoord;
varying vec2 texCoordAni;
uniform vec4 m_BaseColor;
uniform sampler2D m_MaskMap;
uniform sampler2D m_AniTexMap;
void main(){
float Mask = texture2D(m_MaskMap, texCoord).r;
vec3 AniTex = texture2D(m_AniTexMap, vec2(texCoordAni)).rgb;
gl_FragColor.rgb = m_BaseColor.rgb * Mask * AniTex;
gl_FragColor.a = Mask;
}[/java]
Material Defenition:
[java]MaterialDef FakeParticleBlow {
MaterialParameters {
Texture2D MaskMap
Texture2D AniTexMap
Float TimeSpeed
Color BaseColor
Boolean Animation_Y
Boolean Animation_X
Boolean Change_Direction
}
Technique {
VertexShader GLSL100: Shaders/FakeParticleBlow.vert
FragmentShader GLSL100: Shaders/FakeParticleBlow.frag
WorldParameters {
WorldViewProjectionMatrix
Time
}
Defines {
ANY_DIR_Y : Animation_Y
ANY_DIR_X : Animation_X
CHANGE_DIR : Change_Direction
}
}
Technique FixedFunc {
}
}[/java]
So now it’s m_TimeSpeed that doesn’t work? Can we see the latest j3m that isn’t working right?
Yes, of cource. This is my material:
[java]Material Fake_Particle_Blow : MatDefs/FakeParticleBlow.j3md {
MaterialParameters {
MaskMap : Flip Models/jme_FakeParticleBlow/mask.png
AniTexMap : Flip Models/jme_FakeParticleBlow/particles.png
BaseColor : 2.0 1.0 0.5 1.0
Change_Direction : true
Animation_Y : true
TimeSpeed : 0.5
}
AdditionalRenderState {
FaceCull Off
Blend Additive
}
}
[/java]
And this is my code with j3m Material. “fire” is a plane (polygon) model:
[java]package ShaderBlow;
import com.jme3.app.SimpleApplication;
import com.jme3.asset.AssetKey;
import com.jme3.asset.TextureKey;
import com.jme3.material.Material;
import com.jme3.renderer.queue.RenderQueue.Bucket;
import com.jme3.scene.Spatial;
import com.jme3.texture.Texture;
import com.jme3.util.SkyFactory;
/** Sample 6 - how to give an object’s surface a material and texture.
- How to make objects transparent, or let colors "leak" through partially
- transparent textures. How to make bumpy and shiny surfaces. */
public class FakeParticleBlow1 extends SimpleApplication {
Spatial fire;
public static void main(String[] args) {
FakeParticleBlow1 app = new FakeParticleBlow1();
app.start();
}
@Override
public void simpleInitApp() {
// TextureKey skyhi = new TextureKey("Textures/Water256.dds", true);
// skyhi.setGenerateMips(true);
// skyhi.setAsCube(true);
// final Texture texhi = assetManager.loadTexture(skyhi);
TextureKey skylow = new TextureKey("Textures/Water32.dds", true);
skylow.setGenerateMips(true);
skylow.setAsCube(true);
final Texture texlow = assetManager.loadTexture(skylow);
rootNode.attachChild(SkyFactory.createSky(assetManager, texlow, false));
fire = assetManager.loadModel("Models/jme_FakeParticleBlow/FakeParticleBlow.j3o");
fire.setMaterial( (Material) assetManager.loadAsset(new AssetKey("Materials/FakeParticleBlow.j3m")));
fire.setQueueBucket(Bucket.Transparent);
rootNode.attachChild(fire);
flyCam.setMoveSpeed(5);
}
@Override
public void simpleUpdate(float tpf){
}
}[/java]
And here you can grab textures and a model:

Hi @pspeed ! I just want to ask about the bug with g_time… Is it really bug?
I have just released my shader library. ShaderBlow 0.3.
Now you can test it with mercurial. JMP Project: hg clone https://paulgeraskin@code.google.com/p/jme-glsl-shaders/ jme-glsl-shaders
Or download: http://code.google.com/p/jme-glsl-shaders/downloads/list
Threre are 2 examples. with j3m and with code. j3m still does not work.
