Hello again,

i have a teleporting system over mirrors player can bound together and place. The mirrors just looking horrible. Is it possible to render a plane, that has a reflection, like a real mirror, that player will see him self when standing in front?

If it is too much, i will use normal textures, but a real mirror would be great.

you can look at mrcrayfish's furniture mod code, he has a good mirror block: https://github.com/MrCrayfish/MrCrayfishFurnitureMod/blob/master/src/main/java/com/mrcrayfish/furniture/blocks/BlockMirror.java

There's also a thread around here (probably the same mod). IIRC, the strategy was to implement something like the front-view camera (hit F5 a couple times) and skin the mirror with what it is seeing. Just make sure that mirrors can't see each other.
