I have no plan to release it in the future yet. Basically, this tool convert maps and models from Medal of Honor: Allied Assault, it could probably convert other q3 game with some minor code changes but I primarily focus on this game.
Here are two pics, one showing the map of the quake 3 based game, and the other one after converting & importing the FBX map into level :
The difference is really big even if there is no normal map or anything that improves texturing, UE makes the map prettier.
But as you can see there are some weird shadow artifacts on the wall and on the ground, my normals/tangents/binormals are very good though, they are generated from the tool instead of stealing vertices normals from the bsp directly. The only problem seems to come when brushes are connected to each other, unreal lightmass make it looks like there is an hole between them.
And indeed, I’m generating the lightmap UV from UE4 directly because I thought it’s the most suitable way to do so. What is better for generating a lightmap UV?
