Re: tga to 16 colors?
Why would you want to create a 16 color image from a 24 or 32 bit one? Usualy, if you want a 16 color texture you paint it that way so you can choose your pallet. If you texture in 32bit color and convert to 16 you end up with a dithered mess, especially on DS size textures. If you convert a 1024 x 1024 texture for example… -
Re: Support
Ah, I figured as much with regard to the normal but wanted to double check. Can never decide if mid point is meant to be 127 or 128 and have seen both values used in different applications. Hmm, might need to update my curvature post to reflect that for the mid-point gray. Thanks. -
Fiat 127 (Finished)
Hey all, for practice i am planning on creating this car. I intend on making it as detailed as i feasibly can and making it game ready. Progress so far... -
Is This How a Normal Map Should Look or Am I Doing Something Wrong?
My knowledge of normal map baking is still fairly limited, so it’s possible that I misunderstood some aspects. I’ll try to describe how I currently see it. First, here are some screenshots of the problem. LowPoly: Low Poly modifires: UV: (I have 2 udims as this model is part of the larger model of car with texel desniinity… -
Re: Normal map from a texture
Yeah just overlay another normal map on top of another one. nDo will do it or do it by hand. Adjust the levels of the one you're laying on top to output only 1/2 of the blue channel (so instead of 0 to 255 take it down to 0 to 127/128) and set the blend mode to overlay. -
Re: Hand painted stuff
Thanks for your tips, Jessica, Lroy, Seirei. I'll make corrections, and next up probably will the the last. About the balls, nothing fancy. A simple sphere, and some planes, with transparency and their rotation tied to the camera rotation. 120 tris, and a 256 map. I tried 128, but it looked too rough in comparison with her… -
Re: Cintiq arms.. Any suggestions
Hey guys, Stumbled upon this thread awhile back... just thought I'd mention that NCIX here in Vancouver has this thing on special for $116 Can and they ship. Just bought mine today and am monkeying around with setting it up! http://www.ncix.com/products/index.php?sku=51666&vpn=45-241-026&manufacture=ERGOTRON -
Re: Maya: Vertex Normal precision errors when smoothing mesh causing normal map artifacts
It's the way computers convert something into an integer by default, 0.9999999 converted to an integer is still 0. I already mentioned it above but will do so again. With unsigned normal maps there is no 90° tangent value, only 90.35294117647059° which is 128 and 89.64705882352941° which is 127, smack dab in the middle of… -
Re: How to paint flow/anisotropic/comb maps in Photoshop.
You have the blue channel set to a constant value (127 or 128 ), so in the areas pointing zero red and zero green, it appears blue. The reason why is because you're dealing with a 3d vector that's flat in the depth plane, and because normals get expanded from 0..255 to -1..1. So the halfway point (127.5) is zero. -
Re: Of Bit Depths, Banding and Normal Maps
That could be handy. I haven't had time to check much in photoshop, but seeing EQ's hard edge cube with dithering across what should be flat areas makes me think that it's dithering the RGB 127.5 to 127 and 128. So maybe that could be scripted to use a curvature mask to at least keep the flats flat if it's actually a…
