Script problem: ZBrush (transformset) gets very imprecise on big tool scales ?

[gamePat]

Hi guys, so I created a quick script for quickly switching between 2 "camera positions". Everything works fine so far, exept when I am storing the transform values of the tool when I zoomed in (tool scale) to the maximum or close to it.
Then, when I switch back to another camera view I stored, the position is not the same as before, the object is actually out of the "camera view".

Since I have no problems with switching between views, that are NOT! zoomed in very close, I suspect ZBrush gets imprecise on big zoom scales.

Btw. I experienced the same problem in the zapplink plugin. There the transformation values don't differ so much, but you still don't get the view back perfectly how it was.

I attached my script, so can anybody please have a look at it ? Or maybe somebody experienced a similar problem already...

Hi Gamepat,

Here's a link to a thread which includes a plugin (called ModelViews.txt) somewhat similar in functionality to what you are constructing. I wrote it to demonstrate several ZScripting techniques and commands implementation - you might find some parts of the listing helpful, especially the MTransformGet and MTransformSet commands which will greatly simplify what you are trying to do.

On the other hand, you may need to store and retrieve some additional information about the WINDOW position, too. I tried to resolve this issue in a general way with another plugin called
