If you are engaged in the 3D industry or plan to engage in the 3D industry, then you must know the VRay renderer, because this is the best rendering engine. VRay is suitable for 3dsmax, Maya, Sketchup, Rhino and other software, providing high-quality picture and animation rendering for 3D modeling software in different fields. VRay is a professional renderer. Users often encounter various problems when installing VRay. When using VRay to render pictures or animations, they often have various settings problems. If you also encounter problems, you can go online. In addition to professional tutorial videos for various VRay renderers, there are also professional answers to various VRay questions to help you quickly learn to use VR renderers.

3Dmax tutorial on using vray renderer to draw photon maps

1. Its principle is to pre-render the photon information in the rendering scene and store it. Generally, it only needs tens of seconds. When the picture is rendered, the stored photon information is read, so that the scene can be directly rendered without having to calculate the photon information in the environment, which greatly saves the designer's time.

2. First, Make sure the renderer is a VR renderer

3. Set the size parameters of the photon map, which needs to be explained here. How big is the photon image? I personally think that the sequence frame should be 1/3 of the image, and the single image should be 1/2 of the image. Of course, this is not a hard rule. You can determine your own size through your own tests. Generally, you don’t need to Exceed the size of the image as it is completely unnecessary and a waste of time.

4. Open the VR panel and change the anti-aliasing to "DMC". This step is so that you don't have to do this step after running the photon, and then put a check mark in front of "don'trenderfinalimage" , the reason is that there is no need to produce pictures when running photons

5. Then, open the GI panel and change the secondary bounce to the light cache

6. Change the quality directly to the parameters of the picture. That's it. You don't need to set it after running the photon.

7. In the "mode" option, select the longest one in the middle (this is the best way to remember), and then in the "onrenderend" option , all three options are checked, which means to automatically store and read photons, then click "Browse" at the back to set the storage path for the photon.

8. Select the storage path and name the photon file

9. Then set the "Lighting Cache" panel below, select the bottom one for "Mode", which is also the longest one (easy to remember~), and then still put the first three checkmarks to set the storage path.

10. Here is the photon path that stores the second bounce. Be careful to distinguish it from the first one when naming it.

11. Then you can render~~~Run and run~ ~Run, run~~~

12. After the photon is rendered, remove the check mark in front of "don'trenderfinalimage" in the VR panel, which means that the image will be rendered next

13. Then change the size here to the size of the image. Do not touch other parameters. Just click render

14. The image is produced, and the speed is much faster than direct rendering. , as the saying goes, "sharpening the knife will make it easier to chop wood." Dear, have you learned it~~
