NOTE: Octane for Lightwave 1.5 has new Octane native projection nodes that should be used to texture the objects without UV maps when possible because the native Octane projections are faster to update in the IPRProvides artists a quick preview of the image prior to the final render, and efficiently allows for adjusting some elements in the scene such as lights, shaders and textures interactively. An IPR image contains shading and lighting data including some for visibility, in addition to the software render. and needs a bit less GPUThe GPU is responsible for displaying graphical elements on a computer display. The GPU plays a key role in the Octane rendering process as the CUDA cores are utilized during the rendering process. memory. See the new projection nodes section in the documentation.
Octane for Lightwave has a custom node that allow image mapping in objects without UV maps. This node currently support several texture projections, like cubic, cylindrical and spherical mapping, and it is very useful for example in architecture visualization projects, with objects that usually don’t have UV mapping.
This node must be linked to the Normal input of the root surface node. It hasn’t nothing to do with normals, but any node must be linked to make possible it’s evaluation.
Use this node is a lot faster than mapping all objects in Modeler before use them in Layout with Octane if you only need simple texture projections, and all it’s parameters can be animated with the “E” buttons. The changes of the projection parameters are updated in the IPR in real time, but node also has a button “Update UV Map in the IPR” that update the IPR if it is not updated by itself.
The node also support the Lightwave texture projections, including the UV projection using a specific UV map. To use the Lightwave texture projections, the UVMAP node reads the texture configuration of the first map layer available in the “T” Color channel of the main surface parameters. Only front projection (or camera projection) mapping is not supported.
This node also has a last option to support a front projection mapping, but it is not complete and only works with objects with small geometry. Octane itself doesn’t support front projection mapping, and it can’t be replaced with UV map coordinates.
