Title: How to declare a portal in Corona Standalone .scn file?
Post by: ohsnapitsjoel on 2013-11-22, 22:18:50

For the newest version of Corona Standalone, is there a different way to declare a portal triangle?

I'm currently doing this, and it's giving me an invalid portal declaration error:

Code: [Select]

portal -2.182 -1.454 2.933 -1.995 0.521 3.174 -1.099 0.221 4.936

I've changed the way portals work, there is now a portal flag for materials, and all objects with material with the flag set to true become portals. To change one of your materials to a portal, put this line into the material definition in mtl file:

Code: [Select]

#CORONA portal
To make portal that does not shade set also its material opacity to zero

This will work with new builds (which I have still yet to make). Add me on skype to coordinate this better.

AHH, I see.  So the portal declaration no longer goes in the .scn file, only the .mtl file, is that right?  And I guess that means I don't have to give it vertex coordinates either.  Hah, I should have tried it out and asked about it here before I did all that work this afternoon!

Awesome, I guess this'll be easier to manage, and it makes more sense in the UI to keep this option together with materials.
