Hi,

I've got a gif with a single colour + transparency that I've loaded into P5.  I'm trying to tint it and display it on screen in different colours.

My problem is that the tint() has no effect when in P3D mode. and when in OPENGL mode the tint works, but the transparent areas go to the colour of the background:

my code:

import processing.opengl.*;
PImage mb;
void setup(){

 size(600, 400, P3D);
//size(600,400,OPENGL);

 mb = loadImage("maze2.gif");
 background(0);
}

void draw(){
 background(0);
 translate(width/2, height/2, 50);
 rotateY(-float(300 - mouseX)/200);
 rotateX(float(200 - mouseY)/200);
 int i;
 tint(0);
 image(mb, -50, -50);
 
tint(0, 153, 204);
 for (i = 0; i < 20; i++){
   translate(0, 0, -20);
   image(mb, -50, -50);
 }
}

I've realized my error with the OPENGL mode.. I was adding the images in the wrong order..

But I still don't understand why the tint function doesn't work with P3D...
