Can anyone help me with the proper usage of a tangent space normal and the gradient bump connection?
I'm testing a product (unreleased, hence no screenshots) which uses normal maps plugged into gradient_bump. They're set to tangent space and 0.5. The figure looks horrible and splotchy if I leave hardware shading on. The texture only looks normal if I either turn hardware shading off, or change gradient_bump to 1.0.
I always leave hardware shading on, but I've never ran into this issue. Is the proper solution to turn off hardware shading, or to change the texture's gradient_bump to 1.0? Or is this a bug altogether?
I'm using PP2014 Game Dev SR5 and set to inches.
/edit
Gamma on the normal is 1.0.

Set it to 1. Leave it there. I honestly don't think the setting was intended to be dialed lower than that, which is why it looks so funky when you do. I always use it set to 1 and only have problems when the team forgets to switch the feature on during beta releases. :-)
