I had a very strange problem. I’ve been doing models for the Source Engine for about 8 years, but I’ve never encountered such a problem.
My task was to create a model of the flag, which somehow would sway in the wind. The only option is animation. I myself could not make it and just accidentally found content for UE4.
I successfully ported the model, applied a texture to it, added the animation and went to check in Garry’s Mod. But I was very saddened by the fact that the model is very strangely illuminated.
The model is only 1 polygon thick. I applied a texture with the setting $nocull 1 to it.
So I tried to make a double flag, where 2 copies of the flag are used to avoid using nocull, but the result remained the same.
So I tried to make a static flag, but again the same light appeared only when the polygons are directed to a certain plane.
I checked the model on the stock map construct, and also on my own. I changed the direction of the sun, -90 or -45, there was no difference.
Please, if anyone knows the problem … help me :surrender:
