psd export vs buffer export

#1

hi wavers :slight_smile:

a simple question: in psd export i find a layer called “diffuse lightning” and in lw buffer export a “diffuse shading” channel

the first similar but more complex (and i think correct) than the second, because is influenced by the lights color etc…and in psd export the composite results are ok, viceversa not using the other…have you ever found this kind of problem?

this is my composite example: left correct, right wrong

Yep. Diffuse Lightning in PSDExport is what was called Illumination pass in ASA_Buffer saver. Shaded Diffuse in Render Buffer Export also stores colors from diffuse illumination, but together with Raw colors. A way to export a clean illumination pass with Render Buffer Export is with DP Filter - Node Editors:

We can even extract an indirect lighting pass or a color bleed pass. Good thing about this is that we can save our passes in more inexpensive formats. This same thing is viable in several compositing applications as well.

wow thanks gerardo, that link is awesome!! now i’ve really need to learn these new features…have you written some step by step tutorial?
for me it should be fantastic! :slight_smile:

thanks again!

Glad you find it useful!

Yes, I gonna write a tutorial for HDRI3D magazine about these experimental tools barely I have some time. The good thing is that we are planning to share the scene files and node configurations as well. Then you can find this content in HDRI3D resources web page.

Cheers,

I might have to pick it up because this is something that would be very useful to know, but looks pretty dang complicated from the post on the Spin Quad forum.

Thank you William! appreciate a lot your comment!

What happens is that this is a bunch of many simple things and it looks complicated, but the structure on how this stuff works is pretty simple. Then, don’t worry, we gonna split this topic in 3 parts, so you can see things gradually. The scenes will help alot too :slight_smile:

I just want to have the time!

Cheers,

Gerardo
