SOON TO BE RELEASED ! Introducing Rombo Sky Welcome to Rombo Tools v1.5! This major update introduces our most powerful addition yet: Rombo Sky engine – a complete volumetric sky system designed for physically-based atmospheric rendering with unprecedented flexibility and control. What sets this renderer apart is its unified approach to atmospheric effects and its[…]
Cloud Stack System Overview Rombo Sky implements an advanced Cloud Stack system that allows for the procedural generation and customization of volumetric clouds. This modular architecture enables users to create diverse cloud formations through a standardized interface that integrates seamlessly with the renderer’s volumetric ray marching system. The Cloud Stack interface consists of three floating-point[…]
Sun Effects System Overview Rombo Sky engine includes a sophisticated Sun Effects system that provides direct manipulation and enhancement of solar rendering through three RGB sockets. This specialized subsystem allows for precise control over solar phenomena and atmospheric interactions that affect the sun’s appearance. The system provides three RGB sockets for effect combination: Socket 1:[…]
Sky Addins Architecture The Rombo Sky engine features a flexible Sky Addins system that allows for the integration of additional atmospheric phenomena and celestial objects through three RGB sockets. This modular approach enables users to enhance the sky with various effects while maintaining proper integration with the main atmospheric rendering. The system provides three RGB[…]

Update v1.4 is fully dedicated to random walk subsurface scattering. We added many new features with an overall speedup and a dedicated workflow for indirect rays. Briefly : Rayleigh scattering Mie Scattering Similarity theory Albedo remapping Diffuse contrast Indirect sampling Continuation rays Overall speedup Added new demo scenes to test updated features and subsurface scattering.[…]
We’ve implemented new exciting features for the SSS random walk shaders. In the while there have also been many optimizations on how sampling is used regard direct vs indirect lighting. We’ve discovered that for the majority of cases we don’t need the extra complexity we introduce with guided (Dwivedi) sampling for indirect sampling/lighting, resulting in[…]
With v1.3 update, we’ve refined rombo reflection shaders : added a new bump mode to romboReflectGeneralized we called ‘Symmetrical’ previous ‘Analitycal’ bump mode has been renamed ‘Tangent’ added a new param ‘Rough IOR’ to romboReflectGeneralized fixed some rare NANs with romboReflect shaders sped up some internal computations Added a new utility node, romboWIFLoader. Added romboTonemapper,[…]
WIF loader is a companion shader for our romboFabricWoven material. Because sometimes we may want to use external nodes to further model things, we’ve added a romboWIFLoader utility that matches romboFabricWoven patterns for increased flexibility in modeling bumps and displacements for example. It can also be used standalone for pattern modelling and general WIF (Weaving[…]
We implemented various tonemap operators for the shader graph so they can be used for color correction or any other task that involves colors, textures and procedurals where they can be applied selectively to single image textures or a bunch of procedural nodes. They work great with HDR inputs like sunsky and environment maps and[…]
With v1.2 update, we are introducing a first batch of exciting new utility shaders : romboTileBlender romboTriplanarMapper romboTextureBlurrer romboThickness All with a single point update ! 😉 These new utilities are under Texture/Utilities folders in your DCC apz of choice. Minor updates for C4D shader structure: romboTransparency is now in the Refract folder (was before in[…]
Rombotools tile blender shader is a powerful stochastic texture synthetizer. It fully preserves texture characteristics and features. Basically it allows to have a texture as input and produce an infinite, non-repeating render-time texture from that. Effectively as soon we start increasing UV repetitions on our texture what we get back is some awful tile artifacts.[…]
