Re: Can someone check real quick of I'm making Normal maps in a proper way? Thanks.
About blending normal maps. Generally, doing a flat overlay or blending mode from one to the other is not going to be the best way. The reason is the way the different channels are read. Red and green are your x/y direction, and are read from 1-127 as negatives (I think), and 128-255 as positives. Blue works differently.… -
Re: Blending Hi-poly Normal Maps with 2D Normal Maps
Be warned: If you overlay the resulting normalmap, level adjust the blue channel to go from 0-127 instead of 0-255. Remember, you're adding vectors here and you'd want the completely flat areas (that just use the normal from the hipoly map) to have a 0 0 0 vector instead of a 0 0 1 because a 0 0 0 vector doesn't alter the… -
Re: Photoshop/Shader - Normal Map - Deepening and Combine
Incorrect. The blue channel has nothing to do with magnitute...Your thinking of how a bump map works. The three channels of a normal map store the ANGLE of normal vectors...Red is X, Green is Y, and Blue is Z. So in any one pixel, there is a value for each channel, giving angle for each axis to direct light which way to… -
Indie Speed Run: Live Play is here!
So a few of us entered the IndieSpeedRun challenge (make a full game in 48 hours). The ISR people have just opened the doors to a month of playing and voting..keep in mind these were all made in 48 hours, with random themes delivered to everyone at the start..should be a lot of downright wacky things in there! Check out… -

Re: gametime's art dump
Fox Engine Office Remake: While the Fox Engine is very impressive, especially the E3 2013 Trailer, I felt that the Office demonstration was doable in CryEngine 3. To prove it, I present you Fox Engine Office Remake. All assets have a proxy model and the level is in real scale. Many assets have POM to further enhance their… -

Re: AO: Unreal Engine 4?
The only thing that *needs* to be linear space is a normal map, though it makes some sense for roughness maps and metalness maps to be in linear space too. However, there is no requirement there, you can have sRGB roughness and metalness maps, you just need to author and preview them as sRGB. The problems arise when you… -
Re: Making sense of hard edges, uvs, normal maps and vertex counts
Essentially, it's because the gradient doesn't have to be accounted for as strongly. Where a normal map is that light blue colour (R/G/B:127/127/255) it means that the normal points in exactly the same direction as the interpolated vertex normal at that pixel. So the more of that colour you have, the less the normal map is… -
Re: Medieval Dungeon [UDK]
I see what you mean about UDK. Honestly I find the lighting and rendering system a bit inferior, as it has a tendency to wash the scene out when baked. It can take alot of trial and error to get things looking proper. With that said here are some solutions for you.. - make sure your normals are aligned right. If going from…
