CentiLeo is a highly efficient GPU path tracer designed for seamless integration with both 3ds Max and Cinema 4D, allowing users to easily manage complex lighting in their scenes. This advanced GPU renderer excels in delivering rapid unbiased path tracing, particularly for intricate lighting scenarios. Featuring out-of-core technology, CentiLeo can efficiently handle enormous scene assets, enabling the rendering of polygon counts, particles, and textures that exceed the limitations of GPU memory. The innovative technology extends the memory capacity for geometry and particles by four times and dramatically increases texture memory limits by a factor of 100. In addition, CentiLeo offers capabilities such as Interactive Preview Render, node-based material and shader editing, displacement mapping, motion blur, subsurface scattering, and rapid noise reduction tailored for multi-materials, glass objects, and mesh lights. Moreover, the software has received support from the Skolkovo Foundation, which has backed some of its research and development initiatives through grants, underscoring the commitment to advancing rendering technology. This combination of features makes CentiLeo an ideal choice for artists and designers looking to enhance their rendering workflows.
