Help with texture processing using RenderToTexture

Scripting Issues

I managed to figure it out, the vertex shader needs to include the model view projection matrix:

Vertex shader:

#version 150

// Uniform inputs
uniform mat4 p3d_ModelViewProjectionMatrix;

// Vertex inputs
in vec4 p3d_Vertex;
in vec2 p3d_MultiTexCoord0;

// Output to fragment shader
out vec2 texcoord;

void main() {
  gl_Position = p3d_ModelViewProjectionMatrix * p3d_Vertex;
  texcoord = p3d_MultiTexCoord0;
}

It’s as simple as that.

I also got the card to appear correctly in the frame using:

card.setZ(-1)
card.setX(-1)
card.setScale(2)
