2 sided Textures?

[SSmutny]

Hello!

Have have a 3ds made mesh loaded in the irrlicht engine.
I have set an ambient light and i can see all textures. But only from
one side of my mesh... from the other side you can watch through the walls.
What can i do? I want the textures to be 2 sided.

If you work in your model program you should set Draw backfaces off. Triangles are viewable from one side. The other side you can't see. You can duplicate the faces and flip them. After that you can set a texture in the inside of your model too.

Ok! Thanks!

I will test this!

Where can i turn off the backfacing?

Sorry, I work with Milkshape. There are that kind of options, it should be something like that...

[SSmutny]

Ok... i have found the option, but it does not work. I can still
watch through the walls of my house from one side.

Help!!!!

You should select, and filp your triangles (don't duplicate all, it would be heavy for your computer) of the point where you can see through. At that point you have to set your textures.

Well instead of creating mirrored faces and doubling your mesh triangles count you could simply put this in your code :

Code: Select all

    node->setMaterialFlag(video::EMF_BACK_FACE_CULLING,false);

Hope this will help you Sasha

you could simply put this in your code

--the only side effect being that your lighting on the inside will look like that of the outside of your model

I think backfaceculling is asking lots of your computers strenght.
