applying fx after 3d tint produces error

[verybigelephants]

When trying to apply the pixelate filter at the end of the drawing loop like this fx.render().pixelate(i).compose(); on a scene with some 3d mesh with some tint() applied to it breaks the renderer and it throws this error https://github.com/cansik/processing-postfx/issues/1

btw great library for simpler quick hassle free post procesing!

Thank you, I will check it out. Do you have a simple example that shows the bug? And are you running it on a mac?

[verybigelephants]

i am running windows and the project i am working with uses kinect and a lot of dependencies, so making it run would probably be a real pain sorry :/

Usually it is really helpful to provide a mcve. Otherwise I have to guess what could be wrong, and how you implemented it. For example here,I don't know if you are going to apply the tint before or after applying the fx...

Just tested it out with a tint(100); in the Simple Effect, and it works. So please provide a mcve so I can investigate further.

sorry i haven't replied in a while, i have a lot of work recently, i will try to provide a working example as soon as possible

Hi, I'm having the exact same problem. There is not truly a need for an mcve: i've just cut everything off and I'm still having the error (I was working on a complex android project, than tried this library in java mode).

Here is the code:

PostFX fx;

void setup(){
    size(360,640,P2D);
    fx = new PostFX(this);
}

void draw(){
  background(255);  
  fx.render().pixelate(100).compose();
}

this is the exception I get when in Android mode using P3D rendering:

Searching on the Internet I've got not so much infos, only that it could be related to shader compiling, but if not everyone is getting this error message I don't know what to think. Anyway the library is awesome, thanks a lot for your work <3
