Repeat X
repeatx
- Number of tiles in X direction.
Repeat Y
repeaty
- Number of tiles in Y direction.
Flip X
flipx
- Flips the image in X.
Flip Y
flipy
- Flips the image in Y.
Reflect X
reflectx
- Reflects the tiles in X. NOTE: Must have Tile Y set to 2.
Reflect Y
reflecty
- Reflects the tiles in Y. NOTE: Must have Tile X set to 2.

overlapu
- Blends the edges together on the right and left edges of the tiles.

Parameters - Common Page
Output Resolution
outputresolution
- ⊞ - quickly change the resolution of the TOP's data.
- Use Input
useinput
- Uses the input's resolution.
- Eighth
eighth
- Multiply the input's resolution by that amount.
- Quarter
quarter
- Multiply the input's resolution by that amount.
- Half
half
- Multiply the input's resolution by that amount.
- 2X
2x
- Multiply the input's resolution by that amount.
- 4X
4x
- Multiply the input's resolution by that amount.
- 8X
8x
- Multiply the input's resolution by that amount.
- Fit Resolution
fit
- Fits the width and height to the resolution given below, while maintaining the aspect ratio.
- Limit Resolution
limit
- The width and height are limited to the resolution given below. If one of the dimensions exceeds the given resolution, the width and height will be reduced to fit inside the given limits while maintaining the aspect ratio.
- Custom Resolution
custom
- Enables the Resolution parameter below, giving direct control over width and height.
Resolution
resolution
- ⊞ - Enabled only when the Resolution parameter is set to Custom Resolution. Some Generators like Constant and Ramp do not use inputs and only use this field to determine their size. The drop down menu on the right provides some commonly used resolutions.
- W
resolutionw
-
- H
resolutionh
-
Use Global Res Multiplier
resmult
- Uses the Global Resolution Multiplier found in Edit>Preferences>TOPs. This multiplies all the TOPs resolutions by the set amount. This is handy when working on computers with different hardware specifications. If a project is designed on a desktop workstation with lots of graphics memory, a user on a laptop with only 64MB VRAM can set the Global Resolution Multiplier to a value of half or quarter so it runs at an acceptable speed. By checking this checkbox on, this TOP is affected by the global multiplier.
Output Aspect
outputaspect
- ⊞ - Sets the image aspect ratio allowing any textures to be viewed in any size. Watch for unexpected results when compositing TOPs with different aspect ratios. (You can define images with non-square pixels using xres, yres, aspectx, aspecty where xres/yres != aspectx/aspecty.)
- Use Input
useinput
- Uses the input's aspect ratio.
- Resolution
resolution
- Uses the aspect of the image's defined resolution (ie 512x256 would be 2:1), whereby each pixel is square.
- Custom Aspect
custom
- Lets you explicitly define a custom aspect ratio in the Aspect parameter below.
Aspect
aspect
- ⊞ - Use when Output Aspect parameter is set to Custom Aspect.
- Aspect1

- Aspect2
aspect2

Input Smoothness
inputfiltertype
- ⊞ - This controls pixel filtering on the input image of the TOP.
- Nearest Pixel
nearest
- Uses nearest pixel or accurate image representation. Images will look jaggy when viewing at any zoom level other than Native Resolution.
- Interpolate Pixels
linear
- Uses linear filtering between pixels. This is how you get TOP images in viewers to look good at various zoom levels, especially useful when using any Fill Viewer setting other than Native Resolution.
- Mipmap Pixels
mipmap
- Uses mipmap filtering when scaling images. This can be used to reduce artifacts and sparkling in moving/scaling images that have lots of detail.
Fill Viewer
fillmode
- ⊞ - Determine how the TOP image is displayed in the viewer.
NOTE:To get an understanding of how TOPs work with images, you will want to set this to Native Resolution as you lay down TOPs when starting out. This will let you see what is actually happening without any automatic viewer resizing.
- Use Input
useinput

- Fill
fill
- Stretches the image to fit the edges of the viewer.

width

- Fit Best
best
- Stretches or squashes image so no part of image is cropped.
- Fit Outside
outside
- Stretches or squashes image so image fills viewer while constraining it's proportions. This often leads to part of image getting cropped by viewer.
- Native Resolution
nativeres
- Displays the native resolution of the image in the viewer.
Viewer Smoothness
filtertype
- ⊞ - This controls pixel filtering in the viewers.
- Nearest Pixel
nearest
- Uses nearest pixel or accurate image representation. Images will look jaggy when viewing at any zoom level other than Native Resolution.
- Interpolate Pixels
linear
- Uses linear filtering between pixels. Use this to get TOP images in viewers to look good at various zoom levels, especially useful when using any Fill Viewer setting other than Native Resolution.
- Mipmap Pixels
mipmap
- Uses mipmap filtering when scaling images. This can be used to reduce artifacts and sparkling in moving/scaling images that have lots of detail.
Passes
npasses
