3dmaxFor rendering rendering, you can try cloud rendering - rendering 100 (supports batch rendering, does not occupy local computer resources, and up to 480 threads greatly improves rendering efficiency).
Problem 1: The image size is too low, resulting in poor rendering results
Cause: The image size in 3DMax is too low, resulting in grainy and noisy renderings.
Workaround:If the material pixel is not high and is used in large numbers, the large image is easy to blur when rendered. It is recommended to preprocess the map in PS and then reassign the model to the material to avoid blurring and noise after rendering.
Problem 2: The subdivision of the main light source is insufficient
Cause: The main light subdivision in 3DMax is insufficient, resulting in a grainy rendering image.
Workaround:The subdivision of the main light is usually set to about 20 to avoid affecting the rendering time too high. For hemispherical and spherical light, its subdivision should be at least 30.
Problem 3: Insufficient material subdivision
Cause: The material subdivision in 3DMax is not enough, which affects the rendering effect, resulting in grainy and noisy images.
Workaround:For the main materials in the scene, such as flooring, latex paint, and materials close to the camera, it is recommended to increase their subdivision to around 20. If the computer configuration is good, you can increase the subdivision value appropriately to get better results.
Problem 4: The impact of glow maps and light caches
Cause: Improper settings of the glow map and light cache caused the rendered image to appear grainy and noisy.
Workaround:It is recommended to set the maximum and minimum ratios to 3, -1, and hemispheric subdivision and interpolation sampling to around 50. The subdivision of the light buffer is recommended to be between 1000 and 1500, with higher values for the better. At the same time, enable pre-filtering and set it to 20.
Problem 5: The DMC sampling parameters are set inappropriately
Cause: The parameters of DMC sampling are not set properly, resulting in noise in the rendered image.
Workaround:It is recommended to set the number of adaptations to 075, the noise threshold is set to 0001, the minimum sample is set to 16-20. By following these settings, you can usually avoid noise in your image.
Problem 6: The ambient light blocking (AO) setting is unreasonable
Cause: Improper setting of Ambient Occlusion (AO) resulted in excessive shadow shadows at structural transitions in the model, resulting in a grainy and blurry rendered image.
Workaround:Press F10 to open the Render Settings panel, find the GI option, and tick Ambient Occlusion (AO). It is recommended to adjust the value to 08. The radius is adjusted to 30 and the subdivision is adjusted to 30. The specific parameters can be adjusted according to the effect of the rendering, and the structure can usually be clearer after turning on AO.
