3D Max common parameters, how to set 3D Max parameters

Case: Wooden flooring.

1.Open the 2000x2000 square mm floor scene and find that the floor texture is too large (assuming each floor is 500 mm long and 50 mm wide).

2.Select the texturer and adjust the number of UV tiles to 4 each.

3.Rendered in perspective.

1.Glossy Wood : Diffuse: Texture Reflection: 35 Gray Specular:

Matte Wood : Diffuse: Texture Reflection: 35 Grey Specular: Glossy (Blurred):

2. Mirror stainless steel: diffuse: black reflection: 255 gray.

Matthew Stainless Steel: Diffuse: Black Reflection: 200 Gray Gloss (Blur):

Brushed Stainless Steel: Diffuse: Black Reflection: Attenuation Map (Black Partial Map) Glossy (Blur):

3. Pottery: Diffuse: White Reflection: 255 Fresnel.

4. Sub-surface stone: Diffuse: Texture Reflection: 100 gray Specular: Glossy (blurry): Bump map.

5. Polished Tiles: Diffuse: Tile Map Reflection: 255 Highlights: Glossy (Blurry): Fresnel.

Normal Floor Tiles: Diffuse: Tile Map Reflection: 255 Specular: Glossy (Blurred): Fresnel.

6. Wood floor: Diffuse: Tile Map Reflection: 70 Glossy (Blur): Bump Map.

7. Clear glass: Diffuse: gray Reflection: 255 Refraction 255 Refractive index.

Frosted Glass: Diffuse: Gray Reflection: 255 Highlights: Glossy (Blurry):

Refraction 255 Gloss (blurring): The refractive index of light.

8. Ordinary cloth: diffuse: texture concave and convex map.

flannel:diffuse:falloff map displacement map.

9. Leather: Diffusion: Texture Reflection: 50 Specular: Glossy (Blur): Bump Map.

10. Water Material: Diffuse: White Reflection: 255 Refraction: 255 Refractive Index Smoke Color Light Cyan.

Bump map: Bath waves.

11. Window screen: Diffusion: color Refraction: gray and white map Refractive index 1 Receiving gi: 2 - Wood grain material.

The main thing is to change the units, mainly to change the inches to centimeters, and not much else.

Workstation level:

CPU (, Intel Core i9 7980XE 18-core professional graphics card (NVIDIA Quadro M6000 price.)

Household grade:

Average: i5CPU + GTX1050Ti, 1060 Medium: i7Cup + GTX1070

Advanced: i9CPU + GTX1080Ti

If you want to be more detailed, you can check the configuration parameters of each version of 3DMAX on the official website.

Quad-core CPUs such as Intel Xeon.

Memory 8G or more (2011 2009 version 4G 8G RAM, 2012 2014 at least 8G, I am talking about this situation is to do scenes, such as 180 square meters of interior modeling rendering).

If the graphics card does not have too high requirements, the mid-to-high-end game graphics card will do the trick (the current graphics card is almost all 2G video memory, which is enough).

The object reference is not set to the instance of the object (error ** is on the line of the session).

After checking a lot of information, I finally solved the problem Roar. I'll share it with you

An important point to know:

Object reference is not set to an instance of an object" issue may be caused by the following possible causes:

1. The viewstate object is null.

2. dateset is empty.

3. DataReader is empty due to SQL statements or DateBase.

4. When declaring string variables, apply variables without assigning null values.

5. The object is not initialized with new.

6. The session object is empty.

7. When assigning a text value to a control, the value does not exist.

8. When using, the obtained object does not exist, or the initial value is not assigned when the value is empty.

9. When using findcontrol, the control does not exist but is not preprocessed.

10. Repeatedly defining the bend caused by the instance error of not setting the object reference to the object.

My error is the sixth, the session object is empty.

Error reason: Calling session["userid"].tostring() should check session["userid"] object is null

In the case of not logging in, session["userid"Soga] is null, and using the tostring() method directly will definitely make an error.

My original **:

protected void page_load(object sender, eventargs e)

strip = ;

struserid = session["userid"].tostring();

strmessage = ;

strpostid = request["postid"].tostring();

strreplytime = ;

Corrected **:

protected void page_load(object sender, eventargs e)

strip = ;

struserid = session["userid"].tostring();

strmessage = ;

strpostid = request["Embedding postid"].tostring();

strreplytime = ;
