More light from one side

[GhostPlayer]

 

What is happening here?

 

Pass from the Doombuilder to the GZDoom, and the lighting effects seem to have more of one side than the other.

 

 

I do not know what I have to do to make them equal

 

PD: my english is very bad (google traductor xD)

I agree that the difference in apparent lighting level is due to fake contrast and is completely normal (outside of ZDoom: https://doomwiki.org/wiki/Fake_contrast).

 

The simple explanation of fake contrast is that it if your wall is oriented exactly along the north-south axis, it will appear brighter and if your wall is oriented along the east-west axis exactly along the east-west axis, it will appear darker. The purpose of this is to provide the illusion of depth in a room.

 

To avoid the fake contrast and have the same brightness applied to your walls equally, there are two ways:

• Move your angles off 90 degrees (for example, move one of your vertices by 1 or 2 units).
• Rotate your entire sector by some amount between 1 and 89 degrees.

Short explanation.

isn't this always the case in the actual doom engine, i thought it was applied to right angles and called "fake contrast"?
