Hi, i have several object ID3D11Texture2D and i need it is transmit in PS, how i can it is realize ?

Depends whether you're using effect files or pure shaders.

For effect files just define multiple variables.

For pure shaders you'll have to specify registers (ex. Texture2D texture0 : register(t0);), they go up to t127 or something like that, then use ID3D11DeviceContext::PSSetShaderResources() with proper indexes (0 matching t0 & so on).

Language is C++. In ID3D11DeviceContext::PSSetShaderResources() used ID3D11ShaderResourceView, and i have ID3D11Texture2D, second problem is it i dont know how many i have ID3D11Texture2D, it is created dynamically, so it is number is no constant, can i union all ID3D11Texture2D in texture array and transmit in PS, i use pure shaders.

can i union all ID3D11Texture2D in texture array and transmit in PS

Yes. How do you plan to use them in shader though? Sounds like declaring many registers isn't an option, try to look at Texture2DArray.

problem is solved, thanks
