How do i make polygons visible on both sides?

HashBrownHamish

I'm making a mesh which is hollow but the interior of it doesn't need to be complicated and the textures are going to be pretty simple so i was wondering if it's possible to make polygons visible on both sides so i don't have that "weird see through effect". And i don't want to use shell modifier because then i the polygon count goes too high.
Using 3ds max of course x)

That would be rendering backfaces, not sure how to do it in Max, but it is usually better not to do this. Reason being is that if you set an object to render backfaces, it will always render every face of the object in all situations, whereas if you did a shell modifier it would add to the total polycount, but the amount of faces actually rendered would usually be lower.

That, or you can duplicate the part you want to be double-sided and flip its normals.

Try adding a shell modifier and bring the thickness way down. Or, you could make the material inside the material editor 2 sided

...if you don't care about the fact you just more than doubled your polycount.

That's why I gave him two options. Poly count doesn't always matter.

Have you tried the shell modifier?

Or perhaps the shell modifier?

Seriously though, need more info on what you're actually trying to do. Does it just annoy you while modeling that you can see through the mesh? In that case there is probably a material setting or something (sorry, not a max guy).

Are you making something like hair where you will have alpha'd planes that need to be visible from both sides? As Per mentioned above, generally best to manually duplicate and flip in that case, as your shader may light the reverse side incorrectly if you disable culling.
