I want to install minecraft forge + the sildurs shader for version 1.12.2. Forge + optifine is installed (optifine in the mod folder) and works. If I only select the optifine profile and load the shader there, it also works. However, if I load the shader in the forge profile and select the shader there, the game crashes and the following error message appears: The game crashed whilst updating screen events
Error: java.lang.NoSuchFieldError: field_191308_b
Exit code: -1
It can't actually be due to the performance of the pc (i7, gtx 1080, 16 GB RAM via the profile were assigned 8 GB to the game).
It could be due to Optifine, the shader could be adapted to Optifine, either try to uninstall optifine because it is "connected" with Optifine or just play with Optifine and then turn it on.
I tried it but it doesn't work. Is also explained on the installation page that you should first install optifine but thank you anyway.
So I just installed another shader and it worked. So it should be because of the sildurs shader
So it's up to the version of the shader
