light texture

just make a purple texture yourself (monochromic) in a .jpeg format, then convert it with wally and make a wad of it.
Let's call the texture "purple".
Then go in your VHE folder/tools. You will find a file called "lights.rad" which you have to open with notepad. Add a line like it's done for the other textures:

purple 151 9 148 150

=> first value is Red, second is Blue, third is Green, last is the brightness of the light, 200 is default but to make it look more cosy I advice you to lower it a bit.

Once this is done, save it.

I'm compiling with Batch Compiler (it's a pretty easy programme) and I don't know how it's done with VHE, so with Batch: go in the RAD tool, notch the case "Light File" and select your file "Lights.rad"

This will make your texture like a light, so you don't need a light object anymore. It should look like on your picture ingame, if not, change the values above and search how you want it to look.
