SCNNode static body with .dae causing issues
ios,objective-c,blender,scenekit
If you don't specify additional options when creating a physics body for a node, what you get is a convex hull encompassing that node's geometry. Because your landscape is a static body, you can make it use a concave shape that more closely approximates the geometry. (Note that this works...
Three.js JSONLoader blender model error: property 'length' undefined
json,3d,three.js,undefined,blender
In my experience so far with the exporter, you have to be very careful which boxes you tick! This length error is usually because you are either not exporting the vertexes, or exporting the scene rather the object....
blender game engine as simulation tool how to include one time calculations
There are two ways to run python code in the game engine, as a script or as a module. A script gets run from start to end while a module is a collection of functions that are called specifically. Modules can also keep global variables that can be accessed from...
Version control of a digital image and the file that produced it
While git keeps the information of all versions around, it doesn't keep all versions in the working tree simultantously. And its interface is meant to show differences between revisions. The problem is that unlike text files, there is no good and common definition about what a "diff" between two images...
Blender Python Material search [closed]
That first line needs to be changed to for i in range(len(bpy.data.materials)):. Alternatively, you could write the following instead: for mat in bpy.data.materials: if str(color) == mat.name: mesh.materials.append(mat) break ...
Cocos3D - background shown through meshes
This issue is caused by the order in which the nodes are being rendered in your scene. In the first model, the hair is drawn first, then the skin, then the eyebrows and eyelashes. In the second model, the hair, eyebrows and eyelashes are all drawn before the skin. By...
Blend2Java.py Shows Errors While Trying To Export
That is one of the syntax changes between python2 and python3. python 2.x you would use print "some text" in python 3.x you use print("some text") What this means is the script is written for blender versions older than 2.50. Since 2.50 blender has used python3. The last update for...
How to create part of an object a separate object on Blender?

Drawing Quads in OpenGL from .obj File
There are a number of issues in this code. I won't go into a lot of detail on most of these, but wanted to at least point out the main issues. OBJ parsing The main part of what you're doing is probably fine as long as you generate the OBJ...
Formulating the “close enough to zero” condition
Like Ami wrote in the comments, it depends on what you're doing. The system epsilon is good for single operation errors, but when you use already rounded values in further calculations, the errors can get much larger than the system epsilon. Take this extreme example: import sys print('%.20f\n' % sys.float_info.epsilon)...
XML3D: Exporting animations from blender
I guess you are referring to this exporter: https://github.com/ksons/xml3d-blender-exporter/ This exporter supports armatures in many but probably not all ways supported by Blender. Here is a very coarse mapping from blender objects to XML3D elements: https://github.com/ksons/xml3d-blender-exporter/wiki/Mappings...
Blender- How to make a 2D object 3D without bevel?
To make a circle a sphere or a rectangle a cylinder, I'd use the spin feature. See: http://wiki.blender.org/index.php/Doc:2.6/Manual/Modeling/Meshes/Editing/Duplicating/Spin Note, Apple's logo doesn't lend itself that well to a spin operation though. If I were trying this, I would probably take the left half of the logo and spin that to...
Three.js Import Blender scene including animations
I got a test object that was created and animated in the center of the scene in blender. When importing this into Three.js the position seems to shift a bit (somewhere between -1.5 and 1.5 units on every axis for me), but that can be fixed manually in Three. This...
Unexpected behavior with the IF function in Blender Game Engine
python,if-statement,game-engine,blender
The reason for the problems are rounding-errors with floating-points. Unfortunately, for floating-points addition and multiplication introduce small errors that can lead to problems with comparisons. Instead, you should use "clamping", which means you prevent over/undershooting by comparing with a threshold, and then setting the value to the threshold itself: acceleration...
overlapping of geometries in Scenekit
I'm a little confused because you are referring to a hole while it seems that your cube does not have any hole and your are adding a plane on top of it. What you are seeing is called depth fighting and it's because both objects have the same z-value, yes....
faces not appear from some angles in three.js
Your faces are probably facing (hehe) the wrong way. Try inverting these faces in blender and then export again. Or try making a double sided material that draws the material inside and outside, but the first option is more efficient. See this tutorial...

Exporting morph targets from Blender to Three.js
Just to close this topic: After some trial and error, we ended up using one keyframe in Blender for each morph target (shape key) we wanted to export. The influence of the morph target was 1 (maximum) on that frame. So for 3 morph targets we had 4 frames (3...
Blender doesn't like FBX 6100 files

No vertices property in exported scene / mesh ( Blender to Babylon.js exporter )
javascript,3d,blender,babylonjs
Ok I found the solution ( used Blender ver: 2.70 ): Instead of vertices property you have to use positions property, AND uvCount is not available in mesh ( I found that value 3 is making mesh showing properly ). It's probably issue with this Blender version ( I have...

fixing sharp looking geometry objects with widthSegmentCount property
This has nothing to do with the quality of your mesh. You are just seeing individual pixels without smoothing. SCNView exposes the antialiasingMode property that will help you get smoother edges (try .Multisampling2X or .Multisampling4X).
Workflow between blender and xcode (scenekit)
SceneKit supports materials exported in DAE from Blender. It doesn't support every possible shading option that Blender has, but unless you're doing exotic stuff it should cover most of what you're looking for. At run time there's no difference between materials loaded from DAE and those created programmatically. What you...
Is three.js ObjectLoader capable of loading textures?
Check out the dev branch. There have been recent commits for texture support for the upcoming r71 release.
Can I set the ambient property of a MeshPhongMaterial to false in a three.js imported Blender model?
three.js,blender,phong,ambient
In practice, the ambient reflectance of the material should usually match the material color, also known as the diffuse reflectance. Doing so will likely make your model look better. For example, you can do this material.ambient.copy( material.color ); or material.ambient.set( 0xff0000 ); three.js r.67...
Opening .blend files using Blender's Python API
The issue with your operator call is that it doesn't accept positional arguments, you need to name each argument - bpy.ops.wm.open_mainfile(filepath="file_path") Blender only allows one open file at a time, when you open another blend file the existing data is flushed out of ram, this normally includes the script you...

It depends a bit on what you want to achieve. Currently you have created a scene in blender containing multiple parts that together result in your BlackHawk helicopter. If you just need a single object in Ogre, you can combine the elements inside Blender into one object, export that and...
Difference between using OpenGL and 3D modelling software
OpenGL provides an API which allows you to interact directly with your graphics card. Software like Blender and Maya add layers of abstraction on top of this, making them easier and more intuitive to use. The approaches are also different: whereas using OpenGL involves writing function calls in order to...

Why is my three.js model missing faces after import?
three.js,blender,normals,uv-mapping
It seems that OBJMTLLoader can handle only triangles and quadrangles, but obj files can describe faces with any number of vertices, but the faces should be convex. If you check your model with http://3dviewer.net, you can see that every face exists, but there are some issues with non-convex faces. So...

Why does the number of vt and v elements in a blender .obj file differ?
Because OBJ and OpenGL use a different definition of "vertex", and handle indices differently. In the following explanation, I'll call the coordinates of a vertex, which are the values in the v records of the OBJ format, "positions". OBJ The main characteristic of the OBJ vertex/index model is that it...
Building Blender on Fedora 20, OSL compilation failing due to LLVM/Clang (mismatch) issues
