Version update of Blender

After Blender 2.49, because the original framework can no longer meet the requirements, the code was completely reconstructed and rewritten from version 2.50, and a new interface was adopted. Blender version 2.50 has made remarkable progress in software, interface, modeling, animation process, tools, python API and so on. This progress is the result of careful study of use cases, years of continuous improvement and community collaboration. Therefore, version 2.49 may not be completely compatible with what is made by version 2.50 and later.

OSL is updated to 1.5, which supports the generation and filling of pictures and videos. Cycles volume rendering and subsurface scattering (SSS) began to support GPU computing (experimental characteristics). Volume sampling has been improved, and now it supports setting samples for "world environment" or "a certain material" separately, which is no longer a whole and adds "multiple importance sampling". Importance sampling of glossy BSDF and anisotropic BSDF is improved, noise is reduced, and the amount of memory used in rendering is reduced. The two BSDF also add Ashikhmin-Shirley illumination model algorithm. The "No caustics" option is split in two (no refraction/no reflection). Incorporating GSoC-20 13 drawing project, the texture drawing mode is greatly enhanced.

The background preview function is improved, and images outside the "view boundary" range are no longer hidden. Node "Select by Group" adds support for "Name" and "Color" types. The video sequence editor added a Gaussian blur filter. Cartoon strokes freely support circular rendering. When setting the Texture Style node, a preset is also provided automatically. The "cartoon stroke line set" rollout has been added to the material items of both engines, and the Python API of cartoon strokes has also been updated. The "interactive real-time rendering" of BI engine adds the calculation method of gradient accuracy and the viewing mode of "material" viewport, which is convenient for drawing concave-convex texture. In the subsequent version A, in addition to fixing bugs, the texture drawing mode was improved. When the grid lacks UV data and maps, a prompt will appear to guide the user's operation, which is no longer automatic.

It is now supported to define the rendering boundary directly from the rendering result, and the rendering notch can be renamed in the property bar. The option of "world background" has been added to the viewport display (only colors can be displayed under BI, and the display under CY will be similar to the background). Highlights in texture shading mode GLSL can now correctly support the transparency attribute of BI materials (the display range is no longer affected by transparency). When using OpenGL mode, selection always tries to select the nearest bone. The Show Brush option can now be displayed in UV engraving. In the Loop section, the fast smoke effect is now modified to generate only smoke nodes (initially, flame nodes will be generated at the same time). Volume rendering adds camera support, which speeds up the rendering of uniform volumes. The "step size" range of the volume is changed to 0 to 1 (originally 0.00000 1 to 100000.0).

The sorting function of deformation keys has been rewritten and now supports sorting to the top or bottom of deformation list (except basic keys). The function of crayons is greatly enhanced, allowing filling lines and editing and modifying vector points that make up lines (providing various commands). In the texture painting and engraving section, the brushes Grab and Snake Hook now support the Strength option. When using shortcut keys to adjust the brush size, you can use the number keys to enter the radius. The polygon selection mask has been improved to highlight only the edges of the selection boundary. When the raster lacks UV data, the default simple segmentation scheme will be changed to cube projection. The animation curve editor added the command of "hide curve" and added circle selection. The video sequence editor adds a background function (it can display the sequence content of the current frame). Add a Waveform Drawing control (all waveform displays can be turned on or off). The display of the sequence has been improved (the entry point and exit point no longer display the part outside the "cut range"), and the range of the composite clip can be displayed when editing the "composite clip". Add the command "slide sequence content" (adjust the In point and the Out point at the same time). Increase the adsorption function. When pressing the G key to move or adjust the entry and exit points of a sequence, hold down the Ctrl key to absorb the entry and exit points of other sequences. A built-in SVG export plug-in is added to the cartoon stroke freestyle, which can output many attributes such as "color, transparency, thickness, visibility, stroke endpoint". Set the "View map cache" check box, enhance the function of the linear "sort key" option (add the "projection X and projection Y" options), and add the "number of chains" check box in the selection. Import the plug-in COLLADA, and add the options of "modify leaf bone" and "find bone chain", which can correctly convert "joint" and "bone". The compatibility of FBX plug-ins is further enhanced. Motion tracking realizes predictive tracking, which makes the tracking speed faster. Fixed the error that the color could not be saved when the new image was solid color. Remarks: The input problem of non-western characters in Winodws platform version has finally been partially solved in this version, and Chinese can be directly input (but only some pinyin input methods are well supported).
