I've found several errors in the Working with Nifs 201 entry in the Oblivion CS Wiki. As these are a very small part of a very informative and often used article, it seems impolite of me to edit the article myself. I would rather contact the author, note the errors I found, and let him make corrections as he sees fit. Does anyone here know who wrote this article?

nvm

I hate nifs - never quite understood them - as can be seen http://www.gamesas.com/index.php?/topic/1080728-add-a-static-model-to-a-creature/
that being said the author can be found here : http://cs.elderscrolls.com/constwiki/index.php?title=Working_With_Nifs_201_:_Meshes%2C_Data%2C_and_you&limit=50&action=history
that being said also do edit it ! not impolite at all - leaving errors uncorrected is arguably more impolite
it is a wiki after all

utumno, thanks for the information. I've copied the text that needs correcting and will work on it off line.

I do have a question relative to this that hopefully others can clarify. The article suggests that, if you're feeling adventurous, you can edit the normals directly in NifSkope. The problem is, the normals are stored as direction cosines, so that the sum of the squares of the three vectors exactly equals 1.00. Mathematically, changing only one vector makes the sum of the squares not equal to 1.00 and therefore makes the set invalid. However in practice this may be Ok. My experiments on this so far have been inconclusive.

Does anyone have any direct knowledge if changing only one vector of the set is Ok in practice?

Always, always, always edit the Wiki when there are problems. Always. Everyone who has submitted anything on the Wiki has released it to be edited - everyone. Every article is open for editing, none of them 'belong' to anyone. Please, the Wiki needs people who will fix problems when they see them!

I understand. I have made a correction to the Smooth Normals paragraph and am still researching the issue with changing a single vector of a vertex normal set.
