I use a randomizer(at runtime, when the blocks get placed using the position) in my tesr to make my crystals(the tileentity(I can make them into non tileEntities) I'm rendering) look different from each other(I don't want to make many different models for performance reasons, and cosmetic one's).

I have seen this thread ( http://www.minecraftforge.net/forum/index.php/topic,28714.0.html ) but I wanted to know if this was the most efficient way to do so(and if it would even work because of the randomizer), and if it was still up to date.

The main 2 differences between TESR and Some Kind of Model are:

-Rendering on screen:

--TESR: each frame

--Model: only when responsible for worldrenderer updates (for example - you break block near it)

-Perforance (comes out of first):

--TESR: Eats more, because...

--Model: Eats less, because...

I know this, but I'm asking if it's possible to do, because of the randomizer but then again I think it should because I thought ICustomModelLoader ran at runtime.
