Why is my V-Ray render grainy?

Why is my V-Ray render grainy?

For example, if you are rendering an interior shot that is lit with sunlight, but do not have enough windows to let the light through, then the image will look grainy. Also, if you are using artificial lights but their intensity is too low, or the number of lights is not enough, then again the image will look grainy.

What is brute force in V-Ray?

The Brute force method for computing global illumination recomputes the GI values for every single shaded point separately and independently from other points. This method is very accurate, especially if you have many small details in the scene.

How increase V-Ray render quality?

In V-Ray for Sketchup, Rhino and Revit, render quality can be improved by dragging the Quality slider to a higher quality preset. and in this case slower render times are expected.

What is GI V-Ray?

Overview. Global illumination refers to lighting in a scene/environment that comes from light bouncing around and off objects (or the environment itself). Global Illumination (or GI) refers to the computation of this effect through computer graphics.

What is irradiance map in VRAY?

In V-Ray, the term Irradiance map refers to a method of efficiently computing the diffuse surface Irradiance for objects in the scene.

What resolution should I render at?

Rendering for Print‍ Use the pixel width and pixel height exactly to render your image. To print a regular US paper ( 8.5″ x 11″ ) at 300dpi (common for inkjet printers), for example, you would need to render a resolution of 2550px by 3300px.

What is frame buffer V-Ray?

The V-Ray Frame Buffer gives you full control over your rendered output, with all the tools you need to review, analyze and post process your images. Keep track of work in progress and fine-tune and manage colors — all in the V-Ray frame buffer.

What is light cache in V-Ray?

Light caching (called “light mapping” in older versions of V-Ray) is a technique for approximating the global illumination in a scene. This method was developed originally by Chaos specifically for the V-Ray renderer. The light cache is built by tracing many, many eye paths from the camera.

What is irradiance map in V-Ray?

Why is Revit rendering grainy?

Render setting is not high enough. If you need super-glossy or reflective materials, you will need higher render settings. 3. Lighting–try experimenting with different light settings and see if it makes any difference.
