Hello,
making some trials on bumpmapping I have also investigated the reason why the Tench class have a strange behavior when bump mapping is enabled and I found the cause for the problem.
This seems due to the fact that, cloning the Balao, some references to the Balao were not updated to point to new Tench files.
I've made a fix and I'm currently testing it. I will upload it, if Ducimus agrees (they are some TMO 2.5 files modified and a new normalmap texture for the Tench).
Hereafter you can find two images of the Tench with normal maps:

On surface
Hope you like it...
Bye,
