Why Photoshop crash when applying filters Nvidia tools-Normal map?
it seems that not all plugins works with cc cs6 - x64 platforms , test it on cs6 x86 or cs5 x86/x64 .
still getting the problem ?
you can use xnormal plugin instead or crazybump or knald . knald is free i think .
take a look at them :
Another good tool is SSBump ://ssbump-generator.yolasite/ -> Also make sure to post your problem into the nvidia or photoshop forum
