Hi there!

I think I found a bug (I hope it hasn't been reported yet and it IS a bug, not like my other bug reports).

I found that when an object has been mirrored, if you use it as an emitter, it emits light opposite to its normal. It corrects if it's mirrored again.

Here are some screen captures; the plane on the right is mirrored from the one on the left:

I couldn't reproduce it here. I've mirrored a plane on all three axes and it renders as expected. Normals are correctly mirrored too, especially if mirrored on Z. Care to share the scene?

[Fernando Tella]

Sure. Give me a second.

It's easily repeatable here. In fact I'm quite surprised you can't do it there. I'm mirroring in one axis only.

Aha. I tested it using a different scenario that's why the lack of luck. I see your point now and it's a bug indeed. When 3dsmax does the mirroring stuff, it changes the triangle winding. Thanks for the report, we'll fix it for the next plugin update.

Heyyy! I finally found a real bug.

good job Fernando!

I'm not surprised.... i have had all sorts of weird things happen after mirroring objects in MAX....

the solution i have found is after i mirror something, i convert that mirrored object into an editable poly. it's almost like erasing the history for that object....

Good tip, thanks!

In the meantime it was fixed and will be available for the next update.
