Here is my status update about my progress with the engine level post processing.

First: The lua part is fully operational. It loads the shader and sets up all needed textures.

Camera layers are now unaffected by having a pp enabled camera.

The render to texture part still needs love. It shows just a red background, what means that all textures are setup correctly. I still have problems when leaving the play mode. You can't see any parts of the scene for now.

PS: I completely rewrote the posprocessing code to respect camera layers and utilize the engine functionality better.

I now have integrated the code I use in my plugin into the engine.

BUT: It is not per camera. It uses the current camera of the current scene. You can't use camera layers for now or use multiple cameras with pp enabled. I will look into that before proposing a patch.

sorry for the late reply, I was working in another town for a week,
it will be valuable to add a simple to use post-processing system to the trunk.

At first it could follow the logic of the camera layer and add two functions to activate/deactivate a post-process shader in lua.
Later we could add something in the editor, but probably only after we move the editor to MGui-v2 (from the experimental branch).

1 : add an "MFXRef * m_FXRef;" to MOCamera to handle the post-processing shaders
there is already "MTextureRef * m_renderColorTexture;" and "MTextureRef * m_renderDepthTexture;" to handle the render to texture.

2 : add the effect rendering to the default MGame::draw

3 : add two lua functions to enable and disable a camera effect. For exemple :

Camera = getObject("Camera")
enableCameraPostProcess(Camera, "shaders/myPostShader.frag")
disableCameraPostProcess(Camera)

4 : in a second time, we also need to add custom variables to the camera to send uniform variables to the shader (to control blur size, focus etc). I'll think about something generic that can create dynamic MVariable.

I am going to do a diff on your version of maratis for the theme support, I want that also. But I didn't see any commits in regards to the shaders.

I was able to do a bloom effect and tonemapping to simulate an HDR effect. I have also done a radial blur shader and some other experiments showing what you can do with GLSL shaders and postprocessing. I will upload some screenshots soon so you can see what can be done with it.

No, you would have access to postprocessing effects like HDR rendering, radial blur, depth of field etc. via GLSL shaders.

Wow, so you are currently able to use depth of field in your games? Is it real-time?

Hey community!

Since I have postprocessing using GLSL shaders up and running inside my game plugin I would like to integrate this functionality into the Maratis main engine so everyone can use it without messing with an external plugin.
You could simply use it from within your LUA scripts without a major hassle.

Anael: Would you accept such a big patch?

Sponk

What would this allow? What does it mean? You can adjust materials without Blender after the fact?
