Items in my mod will designed by the player similar to tinkers but much more fine grained, to the point that a sword could be shaped like a bucket if that is how it was designed. I've got a pretty good idea of how to handle the properties of the item but frankly I suck at graphics.

 

Is it feasible to render an item based on it's NBT and if so how would I attach the renderer to the item.

 

This is what I had in mind for rendering an item:

public class ItemRenderer {

private static final int PARTDIM = 8;

public void RenderItem(IDraftable draft){
	IPartType[][][] parts = draft.GetPartArray();
                int depth = draft.GetPartsDeep() * PARTDIM;
	int width = draft.GetPartsWide() * PARTDIM;
	int height = draft.GetPartsHigh() * PARTDIM;
	for(int i = 0; i < width; i++)//y position
		for(int j = 0; j < height; j++)//x position
			for(int k = 0; k < depth; k++)//z position
				parts[i][j][[k].GetRenderer().RenderPart(i,j,k);// render piece in location, pieces are partially transparent
}
}

 

my items implement IDraftable and each IPartType implementation has an associated IPartRenderer implementation.

 

Edit: I'm sure that the location won't be as simple as integers but is the underlying idea feasible?

You'll want to look at

ISmartItemModel

to create a model based on the NBT. I can't help you with it myself, but it's been discussed in various threads on this forum.

Thanks, I'll take a look and see what I can find.
