Re: how to swap channels in xnormals ?
why are you rotating channels to begin with ? as James mentioned already, use Y+ X+ Z+ default maya coordinates are: R = X+ G = Y+ B = Z+ so if you swap R channel with G channel then you swap Y and X accordingly. you need R = Y+ G = X+ B = Z+ this is where the settings are (screenshot shows setting for Max) -
Re: [MAYA HELP!!!] Rendering and Lights for Demo reel?
Ok, I'll do 2 posts here. This is a noobtastic GI light dome but it works. I've got another one on my work machine I can show you on Monday if this doesn't work. It's real similar though. Paste this in the script editor and hit enter: //PrerenderPyramid v0.7 - (c) Dmitry "Troydm" Geurkov int $lights; float $intensity;… -
What Blender Tasks Are Still Wasting Your Time? Looking for Real Automation Targets
I build Blender tools with a focus on automation and production speed, primarily for game art workflows. Before deciding what to build next, I want to hear directly from people who use Blender seriously and run into the same problems over and over—the kind where you think “this should not be manual in 2026.” I’m not… -
Re: Flipping the green channel in my normal for UDK.
you can flip it in PS before importing or make udk import flip it, or just setup xnormal and ndo up to work with -y. i just set all my tools up to use -y, since UDK is my main game engine, and my viewport shader in maya supports both -y and +y like Joshua Stubbles said, experiment, test things, problem solve before posting. -
[Mel][Maya] Begginer. Is it possible to convert string text back to variable name?
Hey there. Begginer question. Is it possible in MEL to convert string text back to variable name. Here is rough example: $x=smoothstep(0,30,frame); $y=smoothstep(50,60,frame); $a=$x*$y; //down the script i have this: string $a="$x*$y"; Can i convert it back from string variable to $a=$x*$y; consisting corresponding values… -
Re: Your favorite coordsystem
"Y" must ALWAYS be up, just like they taught you in 8th grade math. Why else would they call it "Z-buffering", if "Z" wasn't depth? My problem is, I have an instinctive tendency that makes me think "Y" when I make a move to make something go up and down in a 3D app. The first guy who ever taught me 3D was teaching me… -
Re: learning normal maps (3ds max)
the easy way to figure it out, is to move the light around, to the left or the right of the objects, and look at where the shadows and highlights are., also if your using xoliulshader, there is a checkbox to flip it. and in xnormal in the normalmap settings there is the swizzle. +x +y +z is no flipped green, +x -y +z means… -
Re: Why is the "Slant" in the opposite direction?
I wish Quixel showed it as a check box of "X+ Y+ Z+" or "X+ Y- Z+" instead of the fairly vague "flip x" "flip y"... I assume having both unchecked makes x+y+z+, but I'm not sure on that. If that's the case, then when you finish editing the normal map, save it out as a TGA. Then bring it back into photoshop, and go to the… -
Re: Maya to UDK - normal problems
right fix for the normalMap wrong concept, inverting the green has nothign to do with maya being y=up, it is because UDK uses a normal map swizzle of "+X -Y +Z" while maya is "+X +Y +Z" for udk i export as fbx, with (smoothing groups, Tangens and binormals, and triangulate) checked off in the export optins, and in UDK in… -
Re: Normal Maps
I think what matters here is the bake setup for normals. I've done bakes from 3dsMax to xNormals, 3dsMax only, Photoshop with xNormals filters, and Photoshop with CrazyBump. In any situation, the main thing to be sure off was having X, Y, and Z positive. 3dsMax and UDK both like to have Y-, however, Unity expects Y+,…
