render both sides of polygons

Hello,

is it possible, that irrlicht renders both sides of the polygons of a model?

Backface culling needs to be off for that... you could edit the irrlicht code to disable it, i don't think there is anyway direct call to disable it in irrlicht - though i could be wrong.

I have to ask why would you want to?

it is possible, i think its something like this:

node->getMaterial(0).BackfaceCulling = false;

or something like that (have a look at the irrlicht api

)

good luck!

so i just have to set backface culling off and then both polygon-sides will be rendered?

Code: Select all

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

that should do the trick.

i think that both ways are the same, but i dont know for sure

too lazy to look it up at the irrlicht API (.....which is a task of < 1 minute

you know what i try to say)

see you!

I don't know why, but this doesn't work:

Code: Select all

node->getMaterial(0).BackfaceCulling = false;

This does:

Code: Select all

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

If your node has more than 1 mateial, then node->getMaterial(0).BackfaceCulling = false; will only work on the first material, node->setMaterialFlag() sets it for all materials.
