How to DON'T render some specific planes?

[PaulM3D]

Ok, guys, I'm progressing in Mantra and have got a new question - How to don't render some specific planes?

Real situation - I've got 2 light sources - Sun & Sky. And most of passes(image planes) are rendering for each light source and for each component(diffuse, reflect and refract in my situation).

My passes on exit are: 

1. diffuse_color_noshading - combined light, no component, one pass
2. sky_direct_diffuse
3. sky_direct_reflect
4. sky_direct_refract - don't need
5. sky_indirect_diffuse - don't need
6. sky_indirect_reflect
7. sky_indirect_refract
8. sun_direct_diffuse
9. sun_direct_reflect
10. sun_direct_refract - don't need
11. sun_indirect_diffuse  - don't need
12. sun_indirect_reflect

13. sun_indirect_refract

So, I've got 4 passes(planes) which I don't need.

Haw can I get rid of them? I thought about light contribution, but don't see how to use it in my situation.

 

Yours respectfully,

Paul

It was so simple!

I can just put names by different planes by myself individually. So obvious. I think, thread should be deleted.

It'd be a great resource if you can upload your successful test .hip file. It can help many people!

 

thanks!

Ok, I understand you. Next time - it will defenitely be next time - I'll do this. But in those particular situation it could be better explained by words.

So, when you setting up your extra image planes, you may choose "Direct Lighting(per component)" - "direct_comp" VEX variable. And, as in my case, set "Export variable for each light". But if you don't need some components you should'n use "For each component" toggle. Just create an image plane and input VEX variable like "diffuse_direct", or "coat_direct" - if, for example, you don't need "reflect" component. And for lights - you could set particular light by editing "Light Mask" field. The * symbol means all light. You can exclude particular light by setting ^ symbol before its name. Or just delete * and add name of light you need.

 

Attaching .hip files - it's very good practice, I totally agree! When you can dive in, explore it by yourself. But in my case I can't upload my file because of something like NDA and, unfortunately, I don't have a time right now to make an example.
