Does BGE support normal map blending (animation) ? if anyone answer to my question, I would appreciate it.

Do you mean having 2 or more normal maps applied to a surface and blending between the maps? Or do you mean animating a model that has a normal map applied to it?

I think it is about the Latter, as eat_up mentioned “(animation)”. And yes, you can simply make three Materials: 1 Diffuse Material, 1 Normalmap A, 1 Nrmalmap B … then you set up a Node Material and mix the Materials depending on the Object Color, which can then be changed via Python Script. (You might look up “Alpha Fading” Examples, there are a few on the Forum too – they tend to use Object Color.)

Thank you , but i don’t understand nothing about material nodes , so is there a tutorial ? and btw i truly don’t know how edit a material by python script and integrate that with logic bricks

Material nodes
And generally people don’t use python scripts or logic bricks to change materials. It’s done through the material panel in the properties pane.

My guess is that he meant you can change the material “in game” via python script.

szupek is right I meant “change the material in game via python script”
