Masking problem.

[Makovsky]

Hi, here is 2 renders. One is beauty and second is WireColor mask, ask you can see some objects have similar color to the background? WHY? Now i cant extract picture from background :(

[Utroll]

why don't you just set another color to wire for your background then, corona is just taking the value from 3dsmax for those color ?
With much more objects I tend to render materialID and geometryID pass too, always handy to have more options for postprod

I think that WireColor mask is automatically arrange colors to objects.
In corona elements section there is only CMasking_ID - is it for object ID or material?

WireColor from Corona simply relay the wire color given in 3dsmax.

For further 'automatic' masking passes you have to 'add...' in render elements of render setup panel the 'CMasking_ID' .. then if you scroll down after selecting that new pass you have different option like primitive_ID, material_ID, etc... just give a try to see which ones might save your time in cases like one you had.

When using a studio background you could use a CMasking_mask on that one, to have a sort of alpha to differentiate your work and its background.

Aside Soulburn scripts pack has a 'wireColorRandomizer', but I cannot say if it's taking care to avoid replicated color on different objects or not. I gues it does.

OK, thank you for help.

You're welcome, forum are meant for, or insulting each other as well..

You can of course add many times render element 'CMasking_ID' with each times different options (material, primitive,etc ) for each. You are not restricted to use one. Just in case, I guess you guessed it too.
