Lily Texture Packer

Blender add-on to pack many textures into a single image. Just select all objects to pack textures from and go to menu Objects > Lily Texture Packer. A new image including all textures will be available in UV editor, and UVs of all object will be correctly placed within this new image!

Lily Texture Packer is:

• Easy-to-use No cumbersome options to tune, just select and click;
• Fast Using Numpy and a precompiled C++ packing implementation;
• Efficient Almost minimal lost space, as square as possible texture atlas, keeps only the part of original textures that is actually used by UVs

I want this for free! If for some fair reason you cannot afford the $5 minimum donnation for this product, you are invited to contact me and provide more details about your case. I may (or may not) consider reducing the price.

Extra details The add-on is making the following hypotheses about your scene. You may request for improvements regarding them:
 - Only one UV per object;
 - One texture per material is used. The add-on tries to guess by browsing the node graph which is the baseColor and uses this one;
 - Texture mapping is using UVs (not procedural coordinates);
 - Objects don't share textures (otherwise they will be copied several times in the output, so that UVs don't overlap);
 - UDIMs are not used.
