To achieve that I try to use key-value coding setting parameter of type SCNMaterialProperty . From SceneKit manual on SCNMaterialProperty property contents : You can set a value for this property using any of the following types: ... A texture (SKTexture, MDLTexture, MTLTexture , or GLKTextureInfo) ... So, I construct MTLTexture : Create MTLTextureDescriptor with type MTLTextureType2DArray Create

I can't find any examples of this on web, and it doesn't seem to be working. Is there some built-in limitation where gl_PointCoord can't be used on multiple textures when using GL_POINTS mode for point sprites? uniform sampler2D tex ; uniform sampler2D blur_tex ; vec4 texPixel = texture2D ( tex , gl_PointCoord ); vec4 blurPixel = texture2D ( blur_tex , gl_PointCoord ); I'm sure I am passing in the textures properly, as I can do multi

The code works if I remove forward declaration and move the function above main. Is this illegal code? #version 330 core in vec2 texcoords; out vec4 color; struct Material{ sampler2D tex; // Sampler inside a struct }; uniform Material material; // Forward Declaration vec4 add(Material m); void main() { color = add(material); } // Function Definition vec4 add(Material m) { return vec4
