float4x4 Material parameters

[Paul.Withers]

Hello,

 

Is it possible to pass a matrix (mat4) to a shader uniform via the material?

For example if i define a parameter in the material like so:

<parameter name="transformationMatrix"/>

and in the shader its defined as

UNIFORM float4x4 transformationMatrix;

How do you set that material parameter? I tried setParameterArray() but that doesn't seem to work. Is it possible to set a float4x4 uniform given a material?

Any help would be appreciated!

Hi,

You can use setParameterFloat4x4 directly on shader retrieved from material with fetchShader.

Just define your matrix in the shader like so:

CBUFFER(parameters)
	UNIFORM float4x4 s_my_matrix;
END
