Re: Getting good height from Nvidia-filter normalizing grayscale height
Not criticizing or anything, trying to wrap my mind around it and form my own opinion. I was sold on CB for a while there when viewing Ryan's animated GIF. Then when later viewing the wiki I was convinced that the CB example and Rod Green example were similar, so had to layer on top of each other in Photoshop to compare.… -
Re: Getting good height from Nvidia-filter normalizing grayscale height
Can't say I've used tangent space as much as object space in game art - I know, I'm bad, and need to do more character work - but the example being used here seems kind of extreme. If you've got a big spherical bubble like that in your normal map, you probably need to include it in your geometry instead. In tangent space… -

@Talon: You're right that method isn't the best, or what I would use personally. I was just too lazy to write a full on tutorial. :poly136: What I would do if I only had Photoshop and the Nvidia filter is: EDIT2: IMPORTANT! Do this whole process in a new document, the conversion back from 16 Bit per channel to 8 Bit per… -
Re: Getting good height from Nvidia-filter normalizing grayscale height
Hmm... Eric's blended map looks the same as mine. I did normalize mine before rendering, while Eric's looks non-normalized. But I don't think that accounts for the differences between the renders. I rendered my examples using two simple dot3 lights, with diffuse and specular components. Eric's rendering looks like it has…
