BUNDLES TUTORIALS GALLERY Carrara
The Parchment plug-in lets you combine an image with your render, producing a composite image. You can apply artistic media textures (such as paper or stone) textures, overlay part of an image onto your render or achieve surreal results with odd combination techniques.

The Parchment Dialog

The dialog has two main sections:

The first is the texture section, where you can access a dialog to select the second image that you wish to combine with your render.

The second section is the application box. The first pull down, Effect, deals with whether the effect should be applied uniformly, whether it should fade in or fade out with object distance within the scene or whether it should be applied using a linear or a circular gradient. The Affect menu lets you pick whether it affects just foreground objects, just the background or both. The button lets you edit the parameters of the application method.

The Texture Dialog

The texture dialog is divided into four sections:

The first section Texture Parameters, lets you specify the texture source (either a bitmap or a shader), the texturing method and the channel(s) that it will be applied to. The lower part allows you to specify the overall strength of the effect along with the transparent colour and the range used for the overlay methods.

The second section lets you specify the bitmap to be used for texturing. It is a standard Carrara bitmap dialog.

The third section lets you specify the name of a shader to be used as a texture. You will need to manually create the shader.

The fourth section provides a preview of the scene with the texture applied.

Texturing Methods

Texture

The textures intensity is used to increase or decrease the value in the render.

Lighten

The resulting image is the higher of the value in the render and the value in the texture. The upshot is that the texture only shows where it is lighter than the render.

Darken

The resulting image is the lower of the value in the render and the value in the texture. The upshot is that the texture only shows where it is darker than the render.

Add

The resulting image is the sum of the value in the render and the value in the texture. This can lead to images with a lot of white in them.

Subtract_Texture

The resulting image is the result of subtraction the value in the texture from the value in the render. This can lead to images with a lot of black in them.

Subtract_Image

The resulting image is the result of subtraction the value in the render from the value in the texture. If the render has a predominately black background, this can lead to the effect of the render being carved out of the texture.

Multiply

The resulting image is the result of multiplying the value in the render and the value in the texture. This can lead to images with a lot of black in them.

Divide_Image

The resulting image is the result of dividing the value in the render by the value in the texture. If the texture is dark, it makes the image a lot lighter.

Divide_Texture

The resulting image is the result of dividing the value in the texture by the value in the render. Where the render is dark, the image gets a lot lighter, where it is light, it only gets a little lighter.

Overlay_Above

The overlay Threshold is used to mask the image, with all values lighter than the threshold being placed into the image.

Overlay_Below

The overlay Threshold is used to mask the image, with all values darker than the threshold being placed into the image.

Overlay_Colour

The overlay Threshold is used to mask the image, with all values further away from the Overlay Colour being placed into the image.

Overlay_Colour_AAA

This is like the Overlay Colour option, but information in non-visible parts of the texture is used to anti-alias the corresponding parts of the image.

Texture Channel

This determines how the texture is applied to the image. The options are:

Intensity

The amplitude of all three channels is modified in proportional amounts.

Colour

The amplitude of each colour channel is modified individually.

Red,_Green,_Blue, Yellow,_Cyan,_Magenta

Like colour, but restricted to only the channels listed.

The Application Dialog

This dialog lets you set parameters for your selected application method. The first box contains the Effect and Affect selections from the main Parchment dialog. You may change these values here.

The Application Mask dialog allows you to specify the name of a master shader that will be used to modify the strength of the effect. Where the shader is white, the effect will be applied at full strength, where it is black, the effect will not be applied at all. The Invert check box negates the mask before it is used.

The Distance Parameters are used for the distance fade in and fade out effects. The Lead distance is the distance from the camera before that fade starts, and the Fade Distance is the distance over which the fade completes.

The Gradient Parameters apply to all gradients. The Lead is the percentage of the total length of the gradient that it is held at 0 strength. It defaults to zero, meaning that the value of the gradient starts to increase immediately. The Width parameter controls the width of the gradient as a percentage of the total length of the gradient. At 100% the effect reaches full strength at the end of the line (assuming the lead is set to 0). If the width is reduced the effect reaches full strength more quickly, if it is increased, it reaches full strength later on.

The Invert check box swaps the ends of the gradient around - it starts and full strength and decays to 0 strength. If it is checked, lead determines the distance the gradient is held at full strength. If the Mirror check box is checked, the gradient is compressed to fit into half it's normal distance and is followed by a mirror image of the gradient. This makes it go from 0 strength to full strength and back to zero strength.

The Linear Gradient box contains the parameters for the Linear Gradient effect. The Angle slider sets the angle of the gradient. At zero degrees the gradient runs from the bottom of the screen (0 strength) to the top of the screen (full strength). Positive values rotate clockwise.

The Circular Gradient box contains the parameters for the circular gradient. If the True Circle box is not checked, the gradient will be elliptical, corresponding to the images aspect ratio. The two Center Sliders allow you to move the center of the radial gradient around within the image. The gradient has zero strength at it's center and full strength in the corners of the image.

Enter my serial number?

After purchasing Parchment you will be emailed a serial number. If you open a scene with Parchment or use Parchment in a scene, the Enter Serial Number window will display. Enter your serial number in the field provided and click OK to continue.

Get starting using Parchment?

Parchment is a Post Render Filter. To add it to a scene, select the scene and go to the effects panel. You can select Parchment from the drop down behind the plus sign.

Tips and Tricks

  1.  Remember that you can animate the values, so you can have textures appear and disappear.
  2. The ranges for the gradients are deliberately 'over large' so you can have the effect animated to cross the screen.
  3. You can use an animated texture as the mask, giving you an effect that changes over time.
  4. The Colour keyed Overlay modes allow you to take an image rendered elsewhere against a mono-coloured background and apply add just the object from it into the scene. This can be used for titling as well as for animation effects.

Evaluation Mode

Parchment supports an evaluation mode which allows you to try out Parchment before purchasing it. When the Parchment Enter Serial Number window is displayed, just click Cancel to go into evaluation mode. During evaluation mode, Parchment will apply it's effect in a triangle pattern.

Release Notes

June 08, 2010

  1. Changed where serial numbers are saved to a more modern OS friendly location. This fixes a problem with saving serial numbers on the 64-bit Windows Carrara when UAC is turned on.
