Use special shader in Unigine

[hosein.dophlin]

Hi all

I am a newer user in this forum, and i design shaders for games, i want to use my special shader in Unigine, i wrote that in HLSL format.

How can i import fx file in Unigine?

 

Thanks

there is no easy import of an fx file as UNIGINE uses a different shader concept. Have a look into documentation "Content Creation\Materials Overview\How to Create a New Material" for more infos.

 

You will find UNIGINE material definitions in subdirectory data/core/materials and shaders in data/core/shaders

Thank you ulf.schroeter, i saw a notice on the documentation like this:

 

"Unigine extensions can be divided into three types depending on the interface to be used:

 

//C++ API (components in C++)

Material system (shaders in GLSL/HLSL)

//Interpreter (scripts in UnigineScript) "

 

so you think i can not use HLSL format in Unigine directly?

As UNIGINE supports different rendering systems (OpenGL, D9/10/11, PS3) each shader definition file actually includes different language versions of the same functionality.

For DirectX9/10/11 HLSL format is used, so you can put your existing HLSL code into the DX #ifdef sections. If you also want to support OpenGL/PS3 you have to provide also shader code versions in GLSL/PS3 dialect.
