making a poly surface double sided

Is it possible to switch "ON" the double sided attribute of a geometry? I want my animated curtains to be visible from both sides.

 

Yes, but you need to write a custom shader with culling turned off. You can use strumpy shader editor to whip one up in < 5 minutes.

 

I'm personally having a issue with culling all the time.
Is there a easy way to set up unity to avoid this!?
Im building alot of house type models for a FPS and run into the culling issue from the inside of my meshes often.
I'm using c4d R12.
Any suggestions?

 

Like andorov said, you need to have a shader with Culling Off, see here - http://unity3d.com/support/documentation/Components/SL-CullAndDepth.html

 

It'd be easier for you to simply make the mesh double sided in your 3D app- takes literally about 5 seconds.

 

Making the mesh double-sided is the way to go; turning off the backface culling with a shader doesn't really work because the lighting on the back side will be the same as the lighting on the front side, which is wrong in most cases.

I can only affirm this. Just make the mesh itself double-sided and don't touch the shader for this purpose.

 

my problem is that I have many curtains in my scene, and I already reached my poly limit, so duplicating each skinned curtain twice is not an option. I just wanted to know if it was possible to do that in the inspector, per object bases like in Maya where you just tick ON or OFF "double sided" in the object's inspector, but it seems it's only doable via coding a shader in Unity.

 

Does anyone know how to turn on doubles used polys is C4D R12

 

I guess this doesn't work, because Unity uses another shader ( I don't know about that stuff yet ). I'd just try copying the shader and turning off the backface culling. If it affects any lightning and doesn't look statisfying you could try reducing some polys or so

 

Double sided shader will not "invert" the triangles and make your mesh magicaly double sided. For the GPU a double sided mesh is just 2x polycount, it will make the rendering twice for that material.
So again, the best way is to duplicate and flip your triangles.

even more clear: double sided shader IS NOT an optimization, it's just worse in everything.

 

alright, makes sense now.
thanks for the info everyone,

 

Ok, so I'm trying to make a muzzle flash, the poly object is double sided in Maya but after the import its single sided like everything else you import into Unity.

Is there an option in the Inspector in Unity to change these settings?

 

Are you sure thats its double sided in Maya ? or its just shown double sided in Maya ?
Turn off the "show double sided" option in Maya to get sure that its relay double sided.
