Difference between diffuse renderElement and "texture in extraTex"

[bigbossfr]

Hi,
I have a question : i have for example a ramp connected to the diffuse on a VrayMtl.
I render the RawGI and RawLighting.
I have my result01.

Now in the hypershade i do :
(RawGI + RawLighting) * my ramp, and i connect this network to the illumination of a VrayMtl, and i set the diffuse to 0.
I have my result02.

The problem is : why my result02 is different from my result01 ?
How can i have the same result ?

Thanks.

In the first case, since the texture is directly connected to the material, it influences the GI solution producing color bleeds and so on. In the second case, you are just multiplying an existing GI solution, which was computed with different color bleeding. There is no way you could get the same result in both cases.

Best regards,
