Hello everybody 
I practice blender to make videogames. But to the next version of blender, the BlenderGameEngine will be removed. So I would like know the UPBGE. But, I don’t know how start… There is no tutorial… I would like discover how make a beautiful materials in real time ( as PBR or SSR).
Anybody cans help me?
Thank you 
(and sorry for my approximate English)
I can’t find tutorials for UPBGE aswell. That’s why i stick with BGE. Would be cool if there were good tutorials for UPBGE.
Tutorials that work on BGE work on UPBGE.
There are small differences with some APIs, but nothing to be scared about, just take a look at the documentation and you should be done:
https://pythonapi.upbge.org/#game-engine-modules
https://upbge-docs.readthedocs.io/en/latest/
yeah upbge is just bge + fixes + added features etc.
some highlights.
Static mesh batching - batch a rendercall of a bunch of objects all using the same material
https://pythonapi.upbge.org/bge.types.KX_BatchGroup.html
Geometry instancing - (materials tab) - used for rendering the same mesh 100s of times in a scene using instancing in a single draw call - best for objects like grass, leaves, bushes etc
ReinstancePhysicsMesh( 3rd argument ) = make object unique user of physics mesh
KX_Mesh.copy() = easily create new instances of a mesh without using libNew - less overhead also
BVHTree from KX_Mesh - quickly create BVHTree from triangle mesh physics type
NODES!! - Many new GLSL nodes that make game development easier.

Thank you for explaining some features of UPBGE. There is one more feature like components for quick creating characters. How does it work?
Don’t know specifically for the character components, but PythonComponents in general are just an alternative way of defining logic (than logic bricks).
Its a Python class that you refer to from the UI, with a start and update method. There is also a way to define properties to be set in the UI and picked up at runtime using a args class field:

edit: Updated the broken link with a new one.
Hello
But how use those nodes???
Secondly,
Whats is UI?
Thank you for your answers 
User Interface
look at the locations highlighted with red boxes
after checking either of these then you use the node editor to build
materials.
Hello I searched and I found how use component. But nothing exist on the creation of materials… I search again but if someone discover anything, thank to tell me
search for blender internal materials. its almost the same.
