How to set the renderer image sampling option of VR4. 1 to render a large image?

If you render a large picture, the specific settings are different according to the purpose of the picture. Here I list my habits when rendering big pictures. I won't upload the pictures, please describe them in words.

1, the first point to adjust the settings is the specific degree of shadows, so generally I will first increase the subdivision values of all light sources that generate shadows from the default of 8 to around 25, with the maximum not exceeding 30. This is my personal experience.

2. After the lighting adjustment, of course, it is reflection and highlight, which should be adjusted from the material ball, and the subdivision of reflection has also increased from 8 to about 25.

3. The lighting and materials have been adjusted. It depends on the setting in f 10.

You can adjust the scale of the rendered picture in the General panel. If you use vray's built-in frame cache, you can set it in the basic item. Needless to say, this is easy to understand. Generally, the upload space does not need to be too large, and 800,600 or higher is enough. If you want to print A3 paper, A3 is 420*297mm. As long as you follow this ratio, you can print adaptively on A3. Of course, this ratio can be appropriately increased, but the higher the better. If there is not enough display space, it will not improve much when it is big, but the rendering speed will increase a lot, so it is best to be appropriate.

4. Image sampler (anti-aliasing) is more important. I usually use adaptive DMC for types. This is one of the three options, and it works well for the effect. Anti-aliasing must be turned on. If I use filters, I haven't tested them all, but I use Catmull-rom more. This is what I learned from the tutorial, and I think it is quite good. In other words, don't talk nonsense without research.

5. Indirect lighting is turned on. The first bounce glow map, the second bounce light cache. If the light is ok, there is no need to adjust the magnification, which depends on the brightness of the picture. Halo map is preset to be high (it can be high, but it will be slower), with hemisphere subdivision of 50 or 60 and interpolation sampling of 30. Optical buffer subdivision 1000. The sampling size is 0.0 1, smaller and finer. However, these pictures can be used, so don't improve them unprincipled, otherwise the rendering will be slow and the effect will be little improved.

6. The default dynamic memory limit is 400M, which can be increased appropriately. Generally, a little more than half of your memory is enough.

7, vray log, display information window, I generally think he is very annoying, do not check.

Nothing else. The picture I rendered according to my settings is still quite satisfactory. In fact, there are only a few places to set up. Accustomed to it, you can know which one to move and which not to move at a glance. Having said that, I hope I can help you. If you don't understand, please ask. If you are satisfied, please adopt it.
