How to adjust V-Ray Settings to Speed up 3ds Max Rendering
Slow rendering is a common and painful problem for many 3D designers. There are also many factors that affect the rendering speed. For example, models, materials, lights, rendering parameters, etc. can all affect the final rendering time. Reasonable scene optimization and setting appropriate rendering parameters may make rendering more efficient. So let’s see what can we do to improve rendering speed for 3ds Max projects that uses V-Ray as renderer.
First of all, the most direct and easiest way to improve the rendering speed is of course to optimize the hardware device and increase the computing power used for rendering.
As a cloud render farm that has equipped with massive powerful computing resources around the world, XRender is able to provide global 3d artists a huge amount of high-end render nodes to empower your rendering.
The easy-to-use XRender client is equipped with an intelligent node scheduling system, allowing users to get the most rendering power in the shortest time; at the same time, it comes with an accurate billing system and efficient team management functions that allow supervisors to better Overall project control and budget management.
As for parameter adjustment, here are three V-Ray render parameter settings that are usually used for your reference.
RENDER TEST
The rendering test is mainly the stage of adjusting materials and lights. It needs to quickly preview the light perception and has not much to do with some details such as image noise and sampling distortion, so basically use progressive rendering to test should be enough. You can quickly see a general preview of the overall effect and decide whether to plot or continue to adjust
It is recommended to set the time of the progressive mode to 0, that is, there is no restriction. Since there is no need to pay attention to the rendering time, as long as you can see the light perception, you can directly stop the rendering manually.
GI setting for your consideration：
Rendering parameters for medium quality images (relatively short rendering times)
It is suitable for rendering tasks with less demanding quality requirements or time-critical rendering tasks. With V-Ray noise reduction, the overall quality is still good, and the rendering speed is relatively fast. And surely, in order to reduce render time, part of the quality will instead be sacrificed, so this set of parameters may produce relatively more noise in some details (such as dark corners and other places), or some reasons such as insufficient sampling and loss of details. Distortion phenomenon.
Rendering parameters for high-quality graphs
The parameters in the figure below are more suitable for rendering tasks that pursue quality, but are less time-critical and can cost more.
The above three parameters are only for references and you can also adjust them according to your own image quality. If the rendering time is still very long after the parameters are adjusted, we can check the scene from other aspects.
Model factor: If the rendering of the white film is very slow, it is likely to be caused by the model. Some of the models downloaded from the Internet are very complicated, and the number of model faces is large, which is prone to such situations.
Solution: delete the replacement model, try to collapse the model, use a proxy, adjust the camera angle to reduce the model’s field of view in the camera
Material factors: The subdivision, reflection, gloss, and maximum depth of field of the material will affect the rendering speed. Generally speaking, the material is the most difficult to check and adjust. Most glass, metal, and hair materials will render very slowly. , if the Vray rendering uses a standard material that is not Vray, the rendering time may be too long.
Solution: replace slow rendering maps, adjust material subdivisions, delete material displacement maps, delete or replace objects made by Vr hair, optimize with plugins.
Lighting factor: Too many lights or too large surface area can easily lead to slow rendering speed.
Solution: reduce the light subdivision, try not to apply the dome light, delete the unused models and lights, and reduce the step value in the interpolation of the spline.
