Release notes version 0.2.5
The new 2D filter highlights the silhouette of an object which is stated with render attachments and material nodes. Here is a test blend to check it out: Tutorial_Outline_shader_Upbgeupdated.zip
Now the camera capture uses dshow up-to-date format
The new python functions getAntiAliasing and setAntiAliasing are implemented they both permit to read and set the anti aliasing level. Warning: Setting the level implies recreating the off screen which can be slow.
Very useful to activate filters or other things depending on whether the game user have a graphic card or another.

A basic PBR system was introduced where 3 new shaders were included: Burley BSDF and Lambert Custom BSDF for diffuse and Optimized GGX BSDF for specular. Also, there is a new check under Shading panel for “energy conservation”.
Additionally, 2 new sliders were included under texture influence panel (roughness and metallic).
And all this was also reflected under node editor in material shader.
LOD mipmap for Reflection textures use TextureCubeLod now for better blurring.
Here below you can see 2 examples from Bianca Mello (Thanks!!)
In the purpose of complex filter, data from the rendering other than the final color or the depth could be needed in filter like space reflection or ambient occlusion. The obvious one is the view normal, but any kind of data could be interesting passing from the albedo or diffuse to a debug color for screen ray cast.
To expose such feature to the user, first a list of attachment need to be defined and secondly a way to output to these from simple material or node material.
The attachments are to the number of 7, because the 8th is the first one dedicated to the final color. The UI is defined in "Render" panel under "Attachments" sub panel. A list of 7 items is exposed and the user can add an attachment or remove one from any item, the items have four properties, the name (only for debug), the type : either custom, normal or albedo, in case of custom the properties size and HDR are exposed, they both select the size of data into the attachment texture and it's precision type.
Each GPU material is now tracking 8 out links, the first one is the same as the previous only out link and the other match the extra attachment. They are all iterated in codegen_call_functions to generate the GLSL lines for "gl_FragData[i] = ", a out link is registered using the function GPU_material_output_link.
The attachment type "custom" is dedicated only for node materials where any kind of data could be output to a special node. This node is named "Output Attachment" and has only one input and a property for the index of the attachment, this node is responsible of registering the output link. The other attachment types "normal" and "albedo" are detected in GPU_shaderesult_set and generate link for the view normal and the material diffuse (including vertex color and textures) multiplied by the object color.
From the game engine side, the attachment info are converted into LA_Launcher and put inside RAS_ICanvas, this same class is now responsible of owning and creating the offscreens, by doing this the canvas can also detect properly a resize and recreate the offscreens. Other than that the function are equivalent, GetOffScreen is now called from RAS_ICanvas instead of RAS_Rasterizer.
The attachments are readable from any filters defining the sampler uniform "bgl_DataTextures[7]", this uniform is bind as well as other uniforms in RAS_2DFilter::BindUniforms and the attachments textures in BindTextures/UnbindTextures.
Because GPUOffScreen is not anymore used and is less flexible than hand configuration of a frame buffer, their sources are restored to the blender ones.
Example file: ge_render_attachment.zip
Press key 1 or 2 to select the albedo attachment or the custom attachment, the default one if view normals.
A new category called "Patters" was added in the node editor. Inside this category will be a lot procedural texture nodes.
With this new option MSAA and FXAA antialiasing methods are included by default
Previously parallax node was able to select an other texture component than alpha thanks to a enum option. This option is ported to material texture and so visible in material texture parallax panel. The value is defaulted to alpha for versioning and new textures.
Previously the object info node was doing nothing directly by the fact that GPU_material_bind_uniforms was using nullptr for the last argument corresponding to the float array of object info.
The pass indices used by the object info is stored either in the blender material and the game object under the same variable m_passIndex. The object is coppying this value to the mesh user and BL_BlenderShader::Update is called with the material pass index as argument and inside it get the object pass index from the mesh user. These information are used to set the object info and the random value is computed from the hash of the mesh user client object, a per object value.
The pass index is exposed in python too under attributes:
KX_BlenderMaterial.passIndex
KX_GameObject.passIndex
Example: ge_pass_index.zip
Due to the unstable result of multithreaded bullet this change introduced in the previous version 0.2.4 has been reversed. We save the code to add it in future releases when it is more polished.
Previously the user was obligated to use a 4d vector to simulate a color, now using mahtutils.Color will automatically define a color property in UI.
The type CPROP_TYPE_COL3 and CPROP_TYPE_COL4 are used to define component properties targeting 3 and 4 channels mathutils.Color. mathutils.Color can now optionally support the alpha channel by passing a four elements tuple to its python constructor or passing the size to the Color_CreatePyObject* functions.
