Could someone please point me to where I can create specular, refraction, reflection passes ? I’ve searched and searched and nothing I have found is direct as to creating the passes.

There must be something I’m overlooking when you have to create overrides in passes with objects there must be a faster way to override a parameter without digging though each objects surfaces and adding them to a override.  Is it possible to just plug the surfaces you want into an override for Specular, Reflection, Refraction instead of digging in each objects surface parameters to override ?

I hope someone can please help me !

render pass creation is covered in the manuals.

The manual lists using the preset, pass.  Unless I’ve over looked something it does not list for creating reflection and refraction passes. 

What method do you take when overriding to create reflection and refraction passes ?

I don’t understand how can I override the same parameter for multiple objects, hopefully without going though each object parameters to add to the override.

Put the objects in a partition, and apply the override to the partition?

I knew all along how to create passes :) My memory went foggy over the last few days as I think a cold could be coming down. 

On the MIA_Arch_Material shader, what parameters do I override for creating specular,reflection,refraction passes using this shader ? I’ve tried a few settings within the material and all I get is sliders not check box parameters ?

Also realized that some how taking the scene from 7.x to 2010 causes some things to not work right.

the simplest way to create a reflection/refraction pass:

1. create a new empty pass
2. in this pass create a new partition (name it)
3. put all your objects that should contain reflection/refraction into the partition
4. hide the background partition and the lights partition
5. create a reflective/refractive material and drag and drop it onto your newly created partition
6. by selecting the partition you can create overides, finding under property-overides. there you can select what overrides you want to have for it, like primery rays only, secondary rays, shadow casting, etc
7. preview rendering your pass to see if its all setup ok.

alternative you can create a new render channel output and select the reflection/refraction-render channel

6. by selecting the partition you can create overides, finding under property-overides. there you can select what overrides you want to have for it, like primery rays only, secondary rays, shadow casting, etc

You mention Primary Rays and Secondary Rays.  Are these the options you would override for a reflective and refractive pass ?

What parameters do you override for the MIA_Arch Shader to create a reflection\refraction pass from that shader ?

try this:

go to render manager.
under output-tab you will see a “add"-button. click on it.
select from the list the channel you want to render.
render.

I know that option exists, but you just never know when and if the need arises on how to create them, manually.  That is what I would to know :)
