Shaders Plus provides a collection of node groups for rendering advanced optical effects in Cycles and EEVEE. The system includes modules for real-time shadow caustics, continuous dispersion, and physically accurate thin-film interference.

The shaders are designed to handle complex light behaviors like prism effects and light biases natively, without relying on simple RGB splits or rainbow gradients. It relies on extensive vector math calculations to provide exact control over film thickness and index of refraction (IOR). The package includes 59 shader presets and modular feature nodes that can be connected to existing material setups non-destructively.
