Hi all.

I'm still finding my way around LW 2015, and so far as I can tell, there is no explicit way to render out separate passes for a scene - so if you wanted to render out (for example) separate passes for Diffuse, specular, reflection, shadow etc., how do you do this in LW ?

thanks and best wishes for 2017 to all.

You can do it for example like I showed in Global Materials video tutorials http://globalmaterials.trueart.eu
Video #3 is "matte by surface", Video #4 couple different passes the way you like.
Unlike Image/Pixel shader solutions, it's visible in VPR, so you can adjust settings in the real time.

Thank you sensei. Looks like a lot of detail in those videos - I will have to take my time and watch them slowly.

Thanks.

Look for render buffer export or something similar in the image/ pixel filter dropdown. I think the shortcut key is ctrl+f8. I'm not sitting with LW in front of me so I can tell exactly how to do it, but it is possible without buying/ downloading any third party plugins.

Yes, on my copy of 2015.3, you go to Windows > Image Processing > Processing Tab > Add Image Filter > Compositing Buffer Export, and then go from there.

This will be another way for me to explore MultiPass rendering.

Thank you.

Also worth looking into are plugins Passport (https://sourceforge.net/projects/lw-passport/) and Janus (http://faulknermano.com/janus/) which both excel at rendering-pass/breakout-type functionality.
