Re: Toying around with normal map approaches
These are screengrabs from Maya 2009, High Quality Rendering in the viewport. Doesn't this make them "realtime"? They are using a default Lambert material, meaning no spec. One directional light that are lighting all of them. Oh and of course the 3 to the right each have a bump2D node + file node with normal maps that are… -
Re: Toying around with normal map approaches
Here's another huge comparison picture. I'm preparing stuff for a lecture anyways so might as well post it here. Yes I know that the Object Space shouldn't differ whether lowpoly has soft/hard edges. But since what works in theory doesn't always work in practice I'm not taking any chances. These are once again screengrabs… -
Re: Toying around with normal map approaches
Hey Mop on a related note - iirc the 3dsmax bakes work perfectly in UE3 since the Epic pipeline revolves around the app. So that's a combo to keep in mind. However ... some UT3 props suffer from normalmap mirroring issues. So maybe it's all related in the end? -
Re: Toying around with normal map approaches
Funny, in all engines I worked with, I had smoothing errors like EQ pointed out. In the doom3 engine you guys been working with, the tangent support is a bit more advanced - as the engine treats seperate UV islands kinda like smoothing groups. Also note the kodde removed polys from the bottom and I believe one of the… -
Re: Toying around with normal map approaches
Here is how kodde's maps came out in max when I used them. Note this is a scanline render. I've never used object space normal maps before and I don't know how you display them real-time in the max viewport. Also I had to swizzle some the green channels: Heres a tangent map rendered from max compared to kodde's: Heres a… -
Re: Toying around with normal map approaches
Wait, whats going on here? You can compress OS maps the same as a lot of games compress tangent, with DX5 compression. You cant do 3dc or whatever NM specific compression, because it uses the full 3 channels, but none of those formats are "faster", they're actually slower, because you have to re-calculate that 3rd channel…
