VRAY granite parameters, Vray sunlight parameter problems

This one was tuned out by myself, using a granite procedural texture.

The granite texturing program allows you to simulate granite countertops, floor tiles or stone surfaces.

Color Option - Select the granite texture surface color.

Surface Particle Scale - Controls the scale of granite particles.

Marble procedural texture:

The Marble Texture program allows you to simulate marble materials on countertops, floor tiles or stone.

Color 1: The surface color of the granite texture.

Color 2: The color of the granite veins.

Vein Thickness: This allows you to adjust the thickness of the granite vein.

Miscellaneous veins: This increases the random fluctuations of granite veins.

Vein Noise Scale: This increases the overall direction of the fluctuating granite veins. :

scale: Used to control the degree of vein ore.

Glossy granite, diffuse reflection granite bitmap, reflective attenuation (select fresnel), drag the white grayscale value between 220 230 and the black grayscale value between 10 20. The reflection gloss is given to the subdivision according to the computer situation, and I generally give it to 15.

Rough surface, diffuse reflection to the granite map, reflection to 25, reflection gloss to give, subdivision 15 20 is enough. Texture concave and convex, give a granite concave and convex, preferably black, white and gray**. Of course, you can also do without reflection and reflection gloss, and you can directly concave and convex, according to personal preferences.

Keep in mind that there is no set way to adjust materials in VR.

Marble is generally reflected at 40, and it is enough to give a marble map. If the effect is not good, you can open a little blur, such as to open to. The above are the approximate values, and the specific parameters should be analyzed according to the specific scenario.

Reflection to 60, gloss is not frosted marble or reflection to adjust, frosted, concave and convex 35, environmental output, do not attenuate,

Map Reflection Attenuation (Fresnier).

Highlight glossiness.

Glossiness cancels heel reflections.

Bump 20% map.

Select a background. Wrapping materials can be added).

Will the floor tiles be like that, try it yourself.

You can go and buy the book "Impressions", which is very good and is sold in major bookstores.

It's too general.

Specific to the individual.

The procedure for setting the parameters of the metal material in vray is as follows:

1. After opening the model, press the M shortcut key to open the material library, click any shade ball, and you can name it as you like.

3. Adjust the highlight level and glossiness. For metal, the highlight level is generally 80-100, the gloss level is 60-80, and the difference between the two is generally guaranteed to be about 20, and the specific value can be determined according to the effect.

4. Add floodlights. Select the button on the diagram, click Standard, and select Flood.

5. Then draw four floodlights in the window, generally in the four directions, the left, right, front, and up, if there are too many, it will take time to render.

6. Adjust the pan intensity, the general floodlight is adjusted in about times, of course, the specific effect depends on the individual, after all, the position and number of floodlights will have an impact.

7. Rendering**, when the above work is done, you can render, of course, it is impossible to achieve the effect at one time, you must continue to render, and then move the position of the floodlight. As long as the effect is not achieved, it means that the position and intensity of the floodlight are not adjusted well, as long as you adjust it a few more times.

The parameters of vray sunlight are generally adjusted to increase the intensity, increase the size and subdivide the shadows, as the name suggests, one is to adjust the brightness (that is, the bigger the brighter. Different camera parameters are different according to the scene. You can do as you need.

If it doesn't work, change it to a bigger and smaller one. One is to adjust the size (the size of the sunlight will affect the blurring of the shadow edges, the larger the edges, the more blurred) The other is to adjust the degree of shadow subdivision, if the subdivision is too small, there will be a lot of agitation in the shadow, and the drawing will be adjusted appropriately as needed. (Generally around 16 should be fine).

The specific parameters have to be adjusted with different scenes.,But I don't usually adjust it much (because I'm lazy),Please forgive me if there's something wrong.。

The easiest thing is to find a model with sunlight, and you can see it by opening the model yourself! Hope it works for you!

When using a standard material, check Double-sided under the basic parameters of the shader, and the material will be double-sided when rendered. When using a vraymtl material, check the double-sided under the parameter option, and the material will be double-sided when rendered. Another way to attach a material indirectly is to use the Shell modifier to set the thickness value so small that the thickness is barely visible when rendered.

Even if you don't check both sides, you can display materials in view and at render time. This method is often used on models with transparent refraction effects such as glass, water, etc., so that he can avoid rendering errors because the single-sided model has no thickness and no actual refraction.
