lender 4.2 - 4.5

• A simple but flexible painting system for non-photorealistic rendering in Blender.
• It is a layer-based add-on that resembles the usual painting process. The idea is to simplify the user's work by combining the main settings and tools in one place.

• The Grove is a plugin / add-on (for Blender, and in beta for Houdini) that lets you simulate the natural growth of trees in 3D. The idea is to combine scientific realism—how trees grow, how light and gravity interact, how branches compete for light—with interactive tools so you can art-direct or shape the trees, or just sit back and let them grow.The Grove will grow you the most natural trees ever seen in computer graphics - custom trees that are a perfect match for every project you work on. It is used in architecture, art, research, games, animation and film VFX.  The unique way of growing is what makes it so fast and easy to use, but it doesn't stop there. Bring your trees to life with lush foliage, animated wind, recorded time-lapses, a skeleton of bones and a rich set of attributes.

• Unleash cinematic color power directly in Blender with Colorist Pro, the ultimate addon + LUT pack combo for real-time color grading and creative control. Designed for Blender 4.0-4.5 and compatible with both Cycles and Eevee, this toolset dramatically streamlines your workflow—letting you see your vision come alive right in the viewport.
