Custom dynamic texture

Hello, i managed how to set custom texture in code:

Code (CSharp):

1. noiseTex = new Texture2D(pixWidth, pixHeight);
2. pix = new Color[noiseTex.width * noiseTex.height];      
3. noiseTex.SetPixels(pix);
4. noiseTex.Apply();
5. MaterialPropertyBlock block = new MaterialPropertyBlock();
6. block.AddTexture("_MainTex", noiseTex);
7. GetComponent<SpriteRenderer>().SetPropertyBlock(block);

And my question is, how to set 'point filter' to this texture?
And how to make setting better

Thanks
