Hello Lida:

Your question is about the translation to Spanish of the expression “forward additive pass” that is part of the context “noforwardadd directive to skip generating forward additive pass.”

The complete context includes a lot of lines of improvements. It is the explanation of a series of “Improvements” implemented in the Unity 3.2 related to the Surface Shaders.

BILINGUAL VOCABULARY (related to the context)

1) English expression “surface” = in Spanish “superficie”, “superficies”

2) English expression “shader” = in Spanish “sombreador”

3) English expression “directive” = in Spanish “comando”

4) English expression “forward” = in Spanish “hacia adelante”

5) English expression “additive” = in Spanish “aditivo”

6) English expression “pass” = in Spanish “paso”

ANALYSIS OF THE CONTEXT

The Surface Shader is a directive to made shadows in the surfaces.

It includes different parameters. One of these parameters is the named “noforwardadd” that manages the forward movement when the shader makes shadows.

In the new version of Unity, this parameter was improved in connection with the forward passes.

The meaning of “forward additive pass” is “un paso aditivo hacia adelante”.

PROPOSAL:

- “paso aditivo hacia adelante”

I hope this analysis helps you in your work.

Regards

Domingo
