The new archer editor supports much quicker edits, meaning having a quicker response by the renderer will improve the feel and workflow of the application. |
:The other use of the raytracer is queuing multiple traces in a script file for the purpose of either animation or multi-view rendering can take minutes to hours depending on the complexity of the scene and the amount of frames taken. | :The other use of the raytracer is queuing multiple traces in a script file for the purpose of either animation or multi-view rendering can take minutes to hours depending on the complexity of the scene and the amount of frames taken. | ||
