Re: Maya: Make Planar tool?
I wrote this little script that averages verts on whichever axis you specifiy - I use this one quite a bit. Of course, it doesn't average on anything except the world X ,Y, or Z (or all 3) - so maybe not exactly what you're looking for - but it might help. ////////////////////////////////////////////////////////////// //… -
Re: snapshotasmesh into new mesh
here is the snippet:try( if ( selection.count==1)then theObj = selection[1];--selected object else theObj = pickObject();--pick a scene object with the mouse if superclassof theObj == GeometryClass do --if really picked a valid geometry ( print ("write file..."); tmesh = snapshotasmesh theObj --snapshot the TriMesh of the… -
Re: [Extend Programming] To create you own 3D exporter
for just a model with triangle faces and a UV map (what most formats carry) all you need:* vertex array (3 elements: each holding x,y,z positions) * face array (3 elements: each pointing to the index of the vertex array of that vertex) * uvVertex array (same as vertex, holds U & V coordinates of the UV verts) * uvFace… -
Re: What do you call this? Swizzling?
Packing or channel packing. Swizzle is the ability to change a normal maps XYZ to be in a different order/orientation, i.e. X+Y+Z+ to X+Y-Z+ or Z+Y-X- etc. -
Re: The Toolbag Baking Tutorial
No, it's not a term we've made up, it's the technical name used by rendering engineers. Handedness is actually a sub-set of tangent space, which is one of the reasons why it's automatically set in Toolbag depending on your tangent choice, for instance 3DS Max tangents automatically use -Y. It get's a little murky though,… -
Re: Unreal Developer Kit - MASTER THREAD
ok the UT3 Thread dissappeared, however i guess this is still an issue in UDK could someone tell me why offsetting UVs works different with ScalarParameters as with Constants? Ok an Example, if i have UV coordinates i could add a constant 2, but there is no Constant 2 scalar parameter, right? So i have to append one float… -
Photoshop Normal Map Action Set
Just added the rotate functions this morning and decided it might be worth sharing. http://www.dissidentlogic.com/sgfx/data/ps/sgfx_normal_map_actions.zip Cut and paste from my site: "Set of useful actions for working with normal maps in Photoshop. Overlay: Levels blue channel of current layer to 127 and sets the blend… -
3ds Max - Directional Lightmaps maxscript, matrix/normal basis issues
Hi, I've been writing a maxscript tool to render out directional lightmaps using 3ds Max and while I have the process down the final result isn't quite right. The script rotates the surface normals of the mesh before rendering each of the 3 lightmaps and the lightmaps themselves look correct but when combined back together… -
Re: helpneeded.. maxscript question (uv)
ok although you dont need this I will post it anyway because I prepared it anyway so: here is a code snippet that will read out your texture vertex points if you have a UVWunweap modifiert attached:obj = selection[ 1 ];if (classof (modPanel.getCurrentObject()) == Unwrap_UVW) then ( local uv = selection[1].modifiers[… -
Maya RANDOMLY inverting Normal maps
While using Arnold in Maya, I faced an unusual problem: There are 32 teeth models in the project (16 upper and 16 lower). I use 4 UDIM maps; one for each eight teeth. For some reason, Maya visually inverts the Normal maps along the Y axis ONLY for the lower teeth, while the upper teeth remain as they should (in the final…
