First, sorry for my English, I'm German ^^'
So, I was doing a project a few days ago, and got to finish it. Now I wanted to start making the stuff for another project, and suddenly my game crashes, when trying to render the sequence. What I don't unterstand is why it happens, because I haven't changed anything. I'm working with the same map, the same settings, even the same shader :/
Before you suggest things like reinstall it or anything, I already tried that, and it helped for one sequence. I was able to render it, but after that, it started to crash again and again. So, as you probably understand, I don't want to reinstall Minecraft for every litte sequence I want to render.
I'll give you the crash-report, and some pc and mod data here. But I have to say, that I already tried removing the MoBends mod, and it didn't help a lot.
Java: Java 8
Used Mods: ReplayMod, Optifine (with KUDA Shaders), MoBends
Graphics Card: NVidia GTX 760
Processor: Intel Core i7 3370
OS: Windows 10 (64-bit)
I thank everyone of you in advance for helping me
