Re: Glitch / Special Map - Pixologic didn't even know about this?
I think people are more willing to listen to someone who actually knows how things works, and I mean ACTUALLY works, like normalmaps, bumpmaps, displacements etc, but yours has been mostly guessing in the name of "exploration". You you clearly noted that the specia.. bumpmap looks way better than a normalmap when in… -
Re: Glitch / Special Map - Pixologic didn't even know about this?
Yeah, Doom3 is a good example, you can input a grayscale bump, but it doesnt actually use this to render, it converts it to normals and combines the two(bump+generated) on load(or compiles it into a compressed texture or something once at re-uses that). -
Re: Glitch / Special Map - Pixologic didn't even know about this?
from my (limited) knowledge, a bump map only affects depth, while a normalmap changes the normal direction on a per pixel basis. example: bump map would be good at showing the subtle pores on someone's skin, but you'd want a normalmap to help with the curvature of the skin. -
Re: Glitch / Special Map - Pixologic didn't even know about this?
I'm with EQ. There's not really any good use for this. Nobody uses bump for realtime shaders, and you're much better off just making a proper normal map in the first place than going through some bizarre highpoly->heightmap->filters->normals process. One of the main reasons his example "special map" looks higher resolution… -
Re: Glitch / Special Map - Pixologic didn't even know about this?
Alright, that all sounds good to me. I definitely have to defend myself though and say I do know how to use and make normal maps. The example graphic I made was done slightly in haste and was really only to show the raw idea of what I believed to be something that was going on with the very fine details, so by now, the… -
Re: Glitch / Special Map - Pixologic didn't even know about this?
This is sort of a silly thread, and there are a lot of misconceptions here. A bump map that is converted to a normal, has the exact same limitations as a normal. One can not be "sharper" than the other, its impossible, its limited the the bounds of the pixels contained in the image. If you want more sharpness in your… -
Re: Glitch / Special Map - Pixologic didn't even know about this?
The problem is, these forums are filled with people who work with surface-defining shaders and maps all day long as a living, and many of them know their way around it quite well. There's also the people who would overlay a normalmap unto itself since they heard it was a good trick to enhance the looks of it!, that kind of… -
Re: Glitch / Special Map - Pixologic didn't even know about this?
I definitely am a learning artist, like many here. Yes, I said the normal map, without any tweaks, looked less good than the special map, without any tweaks. Without any tweaks. It was a raw comparison, visually. I also stated the examples maps I made were done quickly and were crap....I was just getting the concept across…
