Hi!
When apply this material .j3m to a object, the texture appears with inverted direction (Red object in the image). But if I load the shader and assign a texture, it appear perfectly (Blue object in the image)
testMaterial.j3m
[java]Material shiny bumpy rock : Shaders/SolidColor.j3md {
MaterialParameters {
Color: 1.0 0.0 0.0 1.0

}
}[/java]
SolidColor.j3md
[java]MaterialDef Solid Color {
//This is the complete list of user defined uniforms to be used in the
//shaders

//This is where the vertex and fragment shader files are
//specified

//This is where you specify which global uniform you need for your
//shaders
WorldParameters {

}
}[/java]
SolidColor.vert
[java]//the global uniform World view projection matrix
//(more on global uniforms below)
uniform mat4 g_WorldViewProjectionMatrix;
//The attribute inPosition is the Object space position of the vertex
attribute vec3 inPosition;
attribute vec2 inTexCoord;
// El tipo varying conecta con otra variable del mismo nombre el el Fragment shader
varying vec2 texCoord1;
void main(){
texCoord1 = inTexCoord;
//Transformation of the object space coordinate to projection space
//coordinates.
//- gl_Position is the standard GLSL variable holding projection space
//position. It must be filled in the vertex shader
//- To convert position we multiply the worldViewProjectionMatrix by
//by the position vector.
//The multiplication must be done in this order.
gl_Position = g_WorldViewProjectionMatrix * vec4(inPosition, 1.0);
}[/java]
SolidColor.frag
[java]uniform vec4 m_Color;
uniform sampler2D m_ColorMap;
varying vec2 texCoord1;
void main(){
//returning the color of the pixel (here solid blue)
//- gl_FragColor is the standard GLSL variable that holds the pixel
//color. It must be filled in the Fragment Shader.
vec4 color = vec4(1.0);
#ifdef HAS_COLOR
color *= m_Color;
#endif
#ifdef HAS_COLORMAP
color *= texture2D(m_ColorMap, texCoord1);
#endif
gl_FragColor = color;
