## What's New

- Added TIFF image versions of efeu0_alpha, efeu1_alpha, and efeu_branch_big.

- Added Status Spinner to show loading of images during Ivy Grower tool initialization.

- Added "Soft" and "Image Alpha" options for Alpha channel settings of Adult Leaf, Young Leaf, and Branch Texture Maps.

- Updated Texture Maps to retain thumbnail bitmaps and load only from file as needed to speed up tool reuse.

- Rearranged Birth options.

- Added "Sweep NURBS" creation option with "End Scale" setting and cross-section Spline linkbox for both the Branch Spline and IGSpline creation during birth. This creates a SweepNURBS with Phong and Texture tag and a Branch Material if needed for either spline. The Branch spline or IGSpline as well as a clone of the Cross-Section Spline (if it exists) are childed to the SweepNURBS.

- Fixed undo behavior with rebirth causing last non-related action to be undone.

- Added "Render Instances for Leaves" under Birth tab. Only available in Cinema 4D R11.5 and later. Separate Branch object mesh is implicit with this setting enabled.
Pro: Faster Renders, less memory usage.
Con: Undo will take a long time.

- Added Texture preview for Adult Leaf, Young Leaf, and Branch Texture Maps.

- Updated IGSpline growth to be Linearly Interpolated for smooth growth of the spline instead of point-to-point of the spline.

- Updated Birth to realize a new growth at a new seed and not undo a previous different one in the process.

- Added Status Spinner to show that growth is ongoing.

- Updated HTML documentation
