Go to: Related nodes. Attributes.

The Crater texture can be used to give the appearance of both plateaus and craters when it is used as a bump map on a shader. When it is used as a color map, it provides a psychedelic, colorful effect.

The Crater texture has a special Out Normal attribute, which you can connect directly to the Normal Camera of a shading node to produce bump mapping. (For most textures, you connect the Out Alpha to a Bump 3d node, and the output of the Bump3d node to Normal Camera).

Aside from the attributes listed here, Crater inherits many attributes from Texture3d.

In the table below, important attributes have their names shown in bold in the description column.

Long name (short name)	Type	Default	Flags
balance (ba)	float	0.0
Balance controls the ratio in which the three colors show up in the final texture.
channel1 (c1)	float3	1.0, 0.0, 0.0
Channel1 is one of the three input colors that are mixed together in this texture. Changing this has little effect if the Crater texture is used as a bump map.
channel1R (c1r) float 0.0 The red component of channel 1.
channel1G (c1g) float 0.0 The green component of channel 1.
channel1B (c1b) float 0.0 The blue component of channel 1.
channel2 (c2)	float3	0.0, 1.0, 0.0
Channel2 is one of the three input colors that are mixed together in this texture. Changing this has little effect if the Crater texture is used as a bump map.
channel2R (c2r) float 0.0 The red component of channel 2.
channel2G (c2g) float 0.0 The green component of channel 2.
channel2B (c2b) float 0.0 The blue component of channel 2.
channel3 (c3)	float3	0.0, 0.0, 1.0
Channel3 is one of the three input colors that are mixed together in this texture. Changing this has little effect if the Crater texture is used as a bump map.
channel3R (c3r) float 0.0 The red component of channel 3.
channel3G (c3g) float 0.0 The green component of channel 3.
channel3B (c3b) float 0.0 The blue component of channel 3.
frequency (fr)	float	2.0
Frequency controls the frequency of the perturbation. Increase frequency to increase the detail in the texture, decreasing the size of the detail at the same time.
melt (m)	float	0.0
Melt controls the softness of the edges between the colors in the texture. Increase Melt to make the borders between the colors smoother and wider.
normBalance (nb)	float	1.0
Norm Balance controls the ratio between the low and high normals' perturbance, when this texture is used as a bump map. Norm Balance only has an effect if the Out Normal attribute of this node is connected to the Normal Camera attribute of a shader.
normDepth (nd)	float	5.0
Norm Depth controls how deep the craters will be when this texture is used as a bump map. Increase Norm Depth to make the craters deeper. Norm Depth only has an effect if the Out Normal attribute of this node is connected to the Normal Camera attribute of a shader.
normFrequency (nf)	float	1.0
Norm Frequency controls the amount of rough detail when this texture is used as a bump map. Increase Norm Frequency to make the texture rougher, with finer detail. Decrease it to make the roughness larger-grained. Norm Frequency only has an effect if the Out Normal attribute of this node is connected to the Normal Camera attribute of a shader.
normMelt (nm)	float	0.0
Norm Melt controls the softness of the crater edges when this texture is used as a bump map. Increase Norm Melt to make the edges softer. Animate this texture to make the cratered surface look like it is melting. Norm Melt only has an effect if the Out Normal attribute of this node is connected to the Normal Camera attribute of a shader.
normalCamera (n)	float3	0.0, 0.0, 1.0
The input normal to perturbate
normalCameraX (nx) float 0.0 The X component of the input normal
normalCameraY (ny) float 0.0 The Y component of the input normal
normalCameraZ (nz) float 0.0 The Z component of the input normal
outNormal (o)	float3	0.0, 0.0, 1.0
Out Normal. Connect this attribute directly to the Normal Camera attribute of a shader to use this texture as a bump map. If you connect it directly in this way, then you can use the various Normal attributes (above) to control the qualities of the bumps.
outNormalX (ox) float 0.0 The X component of Out Normal
outNormalY (oy) float 0.0 The Y component of Out Normal
outNormalZ (oz) float 0.0 The Z component of Out Normal
refPointCamera (rpc)	float3	0.0, 0.0, 0.0
The current reference sample point that has to be shaded
refPointCameraX (rcx) float 0.0 The x component of the current sample position
refPointCameraY (rcy) float 0.0 The y component of the current sample position
refPointCameraZ (rcz) float 0.0 The z component of the current sample position
refPointObj (rpo)	float3	0.0, 0.0, 0.0
The current reference sample point that has to be shaded
refPointObjX (rox) float 0.0 The x component of the current reference sample position
refPointObjY (roy) float 0.0 The y component of the current reference sample position
refPointObjZ (roz) float 0.0 The z component of the current reference sample position
shaker (sh)	float	1.5
Shaker controls how 'perturbed' the texture is. Increase Shaker to make the texture more detailed, as though it has been "shaken up". If the crater node is being used as a bump map, increase Shaker to increase the number of craters and valleys.
