I am getting above error when trying to obj.ray_cast() from a copy of an object: obj = bpy.data.scenes[0].objects["Sphere"].copy() is_hit, hit_loc, hit_normal, index = obj.ray_cast(localA, localB) …

I have the following custom prop: class Settings(bpy.types.PropertyGroup): enabled = False state = { "some_data": None, # edit: this points to numpy array "some_other_data": …

I am not sure what I am missing, but all I get is a value of 1 on every return.. value_texture = numpy.zeros((100 * 100), dtype=numpy.float32) for y in range(100): for x in range(100): lo …

This works: value_texture[loc] = mathutils.noise.hetero_terrain((x*.01, y*.01, 0), 1.0, 2.0, 1.0, 1.0, 1)

Turns out I had to apply location to the BMesh I generated, I have edited code above to work: bm1.transform(scene.objects[obj_now].matrix_world) bm2.transform(scene.objects[obj_next]. …

Edit: I think I have found what I was looking for bpy.app.handlers.load_post, but will leave it open for maybe better suggestions. I have a class variable that is stored in bpy.types.Scene.my_class, w …

Using a handler to remove my_class: from bpy.app.handlers import persistent @persistent def handler_new_scene(scene): del bpy.types.Scene.my_class I think del scene.my_class will work also, or s …

Does anyone know how to extend custom nodes to support asset drops from the asset browser? If you go to the script templates > Custom Nodes sample and run it. You can add this custom node tree as an a …

This is a follow up to How to check if two meshes intersect in python with BVH Tree? It appears that just calling overlap() on the BVH tree of two objects is not enough. …

Current very slow method (code reduced): obj = bpy.context.active_object vgroups = obj.vertex_groups.new(name="test_layer") for loop in obj.data.loops: vindex = obj.data.loops[loo …

If not explicitly defined, the python class name is used. … If not explicitly defined, the python class name is used. …

I just began learning Blender Python API, not sure if what I am asking is possible. I want to write a script to distribute objects on the surface of a mesh based on RGB value of a generated texture. …

I also tried calling image.update() and image.pixels.update() on the Python side hoping for a miracle lol. void EXPORT set_all_pixels_to_white(ImBuf *buf) { float *pixels = buf->float_buffer.data; … >x * buf->y * buf->channels; for (int i = 0; i < num_pixels; i += buf->channels) { pixels[i] = 1; pixels[i + 1] = 0; pixels[i + 2] = 0; pixels[i + 3] = 1; } } Python …

The issue I am having is that at some point, randomly, the pixel data I generate and assign to an image disappears. This usually happens after several large images and pixel data have been created. Th …

How to completely delete an object without using: bpy.ops.object.delete() bpy.ops methods are too slow for my script, so far I am able to delete an object with a simple: del obj But Blender does …
