How does maya render high quality
generating a rendered image always involves choosing whether to affect image quality (anti-aliasing and sampling), rendering speed, or both. Anti-aliasing and flicker
The concave-convex edge or step edge in the pixel-based image or flicker surface is the sawtooth defect.
sawtooth artifacts arise from the point sampling process, which is used in all computer graphics applications to determine information about each pixel. Sawtooth artifacts may occur in different stages of any rendering process.
anti-aliasing is the process of eliminating or reducing these defects. There are many kinds of sawtooth effects (such as grain surface, flicker and concave-convex edge), so there are many ways to control or repair these problems. Many settings can be adjusted to reduce or eliminate jagged artifacts and flicker. Animation flicker
is suitable for Maya software rendering and Maya hardware rendering.
Maya will filter the texture when rendering. If the texture flashes or moves slowly along the object frame by frame in the scene, consider using a lower resolution file texture; Or if you are not using a file texture, adjust the Filter setting in the Effects area of the texture Attribute Editor. Clipping plane defects
Especially in large scenes where the objects are very close, the background surface may appear to show through the nearby surfaces. This is the result of how the clipping plane of the camera determines the depth position of the geometry; The problem arises from the limited accuracy for storing depth information. It is mainly influenced by the following camera parameters: near clipping distance, far clipping distance and camera angle. Rendering speed
Many settings can be adjusted to improve the rendering speed of scenes, surfaces and/or shadows, and the rendering speed of the camera.
reduce memory
in some cases, you can also reduce the memory used for rendering to shorten the rendering time.
reduce file size (Maya vector renderer)
complex scenes and some Maya vector "Render Settings" may produce very large SWF or SVG files, which are not suitable for online transmission.
if you use Maya vector renderer to create SWF or SVG files for online transmission, you can modify the scene and adjust Maya vector Render Settings to find the best compromise between image quality and file size. Improve image rendering quality
adjust anti-aliasing parameters per object
Maya software rendering
By increasing the number of visibility samples in the Attribute Editor of the selected object, flicker of very small objects can be corrected.
adjust the anti-aliasing parameters of the scene (Maya software)
Maya separates the edge aliasing parameters from the coloring aliasing parameters to better control the image quality and performance.
adjust anti-aliasing
Maya Software rendering details
select the Maya software tab in the Render Settings window. The options in the Quality drop-down list and the Edge anti-aliasing drop-down list will drive each other; If you change one option, the other option will also change, and the value of the Anti-aliasing Quality sub-area will be automatically filled in. You can fine-tune any of these settings.
do one of the following:
in the Quality area of the rendering settings window, select a preset.
in the Quality area of the Render Settings window, select Custom, and then manually adjust the settings in Number of Samples, Multi-pixel Filtering and Contrast Threshold.
Maya hardware 2. rendering details
select the Maya hardware 2. tab in the Render Settings window. Expand the Anti-aliasing area to enable Smooth Wireframe or Multisample Anti-Aliasing, and adjust the number of samples.
reducing flaws and flicker
unlike the anti-aliasing method, in the rendering settings window, you can't reduce flaws and flicker by adjusting settings. However, you can independently repair shadow defects, clipping plane defects or animation flicker.
shadow defects (Maya software rendering)
ray tracing shadows are easily affected by the final effect, which is the self-shadow error (triangle similar to smooth surface) caused by subdivision. To fix ray tracing shadow defects, increase subdivision.
clipping plane defects (Maya software rendering)
clipping planes helps Maya determine how far or near an object is relative to the camera. By default, the camera turns on Auto Render Clip Plane so that Maya can sort the geometry as accurately as possible. If the objects seem to penetrate each other, turn off Auto Render Clip Plane and set Near Clip Plane to 1..
Improving the rendering quality will make the rendering slow. You can try to use shading cloud rendering to solve the problem of slow rendering, saving rendering time and resources.
