it_matrix
Sorry for the questions here. I'd like to implement node to the code below, but the method does not know. Maybe, would I be able to get a hint about this?
----------------------------------------------------------------------------------------------------------
capCoord.x = dot(UNITY_MATRIX_IT_MV[0].xyz, v.normal);
capCoord.y = dot(UNITY_MATRIX_IT_MV[1].xyz, v.normal);
----------------------------------------------------------------------------------------------------------
capCoord.x = dot(UNITY_MATRIX_IT_MV[0].xyz, v.normal);
capCoord.y = dot(UNITY_MATRIX_IT_MV[1].xyz, v.normal);

Mathematical understanding of the matrix is insufficient me. It is also the same coding. ShaderForge of you to understand me Shader has become a big help. However, I think I want to get a hint of a portion clogged.
Thank you! Have a nice day...
