Shapes

BMD places Shapes in the Krokodove Image Create Tools and describes concentric circles and squares. It is an image generator with its own Width/Height and Render controls, despite its name resembling the sEllipse/sGrid/sRender shape system.

First and Last describe the first and last pattern sets. The developer’s Krokodove v4.15 manual explains intermediate sets when Number Of Line Sets is at least 3. These tabs are not automatically created first-frame and last-frame keys.

One line set itself contains repeated concentric elements. Number Of Line Sets 3 does not mean exactly three circles. Spacing controls density within a set; the set count controls a separate structural level.

For a spatial comparison, give First and Last different centers, angles or colors on one frame and compare 1, 2 and 3 sets. Then change the frame without keys: changing time alone should not transform First into Last.

Global In/Out limits the generator’s active range. The original PNGs show 0–119, or 120 frames. Add explicit keys to Angle, Center or another animatable control for motion; the range itself does not interpolate between tabs.

Spacing and Thickness solve different problems: separation between elements and their width. Softness softens a boundary. Scaling/Increase vary the corresponding property through the pattern; a control label alone does not define the current implementation’s exact formula.

Dot Spacing and Dot Length shape the dashes, while Dot Softness affects their ends. For a clean comparison, first leave every Scaling/Increase at 0 and change one dot control. The captured Dot Length 0.5 is a useful reference to compare against shorter segments.

Color 1/2 set the set colors, while Overlap controls their interaction at intersections. The retained menu contains Maximum, Add, Multiply and Screen. No mode is presented as universally producing a correct matte or safe HDR result.

Super-Sampling controls rendering quality. The PNG shows options from 1x1 to 16x16. Increase it after designing the pattern, then compare thin diagonals and moving dashes at the final frame size.

Image sets the raster format and its interpretation. For a repeatable example, disable Auto Resolution and set 1920×1080, Pixel Aspect 1:1 and Full Frames. Check Color Space/Gamma switches in the context of the composition’s color workflow.

For a mask stream, send the Shapes image to Bitmap and explicitly choose a channel. The lesson matte graph uses Luminance from a white pattern; image alpha is inspected separately and the mask feeds Merge.EffectMask.

Current control labels are checked against all six original PNGs. BMD21 confirms the tool’s purpose and data type; the historical developer manual clarifies its set concept. It is not native-render validation or a guarantee of exact formulas or compatibility across older versions.
