# VIOSO Warp Blend

Exaplan can apply warping and blending to the multi-projection canvas based on a VIOSO (.vwf) file.

The file can be generated from [VIOSO Calibration software](https://docs.vioso.com) (Anyblend, VIOSO6, VIOSO7 or Projection Tools - Mapper2D). It needs to be in the following format: 

* 2D
* Single Mapping, no splits
* Single file (merge all).

Below is an example with a 2x channel calibration file opened in the viewer:

1. To activate the warp & blend in Exaplan, go to the  [`Configuration file`](/configuration/configuration-file.md) and set the `VIOSOWarpBlend`  parameter to "**true**".
2. Next, you need to configure the VIOSOWarpBlend .ini file to reference the (.vwf) export as shown below:

`\Exaplan_Data\StreamingAssets\VIOSOWarpBlend.ini`&#x20;

```tsconfig
// VIOSOWarpBlend.ini for Exaplan
[default]

logLevel=2

base=[1000, 0, 0, 0; 0, 1000, 0, 0; 0, 0, -1000, 0; 0, 0, 0, 1]
eye=[0,0,0]
near=0.15000 ;the near plane clipping distance
far=10000.00000 ;the near plane clipping distance


bAutoView=1;
autoViewC=1.00000 ;
bTurnWithView=1
bBicubic=1
bDoNoBlack=0


;Path for the calibration file exported from VIOSO.
calibFile=C:\Users\AJ\Documents\VIOSO\VIOSO6\Export\screen.vwf

;Camera name in Unity
[ProjectionCamera]
calibIndex=0


```
