Myproblem: weird rotation when using TRSRTransformation while baking IModels caused by the rotation axis not being in the center of the block.

Solution: Use TRSRTransformation.blockCenterToCorner to convert your TRSRTransformation (even though you would intuitively use TRSRTransformation.blockCornerToCenter).

I tend to use TRSRTransformation quite a lot as I often do manual model baking. I noticed when constructing a new TRSRTransformation , my rotation around y-axis doesn't happen around the center of the block, but rather on one of its corners. And also mixing translating and rotating together doesn't happen as I expected it to happen.

 

So how do I combine

1) translating (let's say 0.5 blocks north) and then

2) rotating by 90 degres around y-axis (with the axis going through the center of the block)

Found the answer

Translate (-0.5,-0.5,-0.5)

Rotate

Translate (0.5,0.5,0.5)

Well this doesn't work:

 

TRSRTransformation.blockCornerToCenter(new TRSRTransformation(
					closed ? null : vector, 
					null,
					null,
					TRSRTransformation.quatFromXYZ(0, (float) Math.toRadians(90 * direction.ID), 0)));

 

It gets properly rotated, but again it also gets translated weirdly
