In this guide I want to explain how you can add shaders to your InfinityEvolved mod pack.
What to expect:
A beautiful world to explore and build in.
A huge fps reduction. Don't do this if you already are low on fps. I have a GTX1060 6Gb, i5-6600k@4.2Ghz, 16Gb ram computer. And my frame rate varies between 20-80fps with shaders, depending on the environment.
Some setup time to try out different settings.
What not to expect:
A glitch free experience. There will be always some block that doesn't look quite right.
What do you need:
FTB InfinityEvolved of course.
OptiFine_1.7.10_HD_U_D8
ThermalShade
A shaders pack: You can use what you want yourself. I'm using Sildur's Vibrant shaders 1.164 Extreme.
Installation:
Open the FTB launcher and edit the IE mod pack.
Open the mod folder and drop both the Optifine and ThermalShade jar file into this folder.
The ThermalShade mod is a path that fixes facades from thermal expansion.
Disable fastcraft.
If everything goes right, you can now start IE.
When minecraft is running, go to options > video settings > shaders.
Open the shader folder and drop the shader zip file in there.
Select the shader in the shader option menu.
Now you should have a working shader pack.
Tweaking:
Now that you have your shader pack running, it's time to tweak some settings to get a better experience. I can't garante that everything will work for you. It will depend on your system and shader pack. Here is the part were you need to experiment.
Go to options > video settings > shaders > shader options. Disable Ice and glass reflections.
Options > video settings > shaders. Set old lightning to "on". This can help with carpenter blocks shadows.
There are many mods that use shader effects ex. thermal expension, botania, thaumcraft. Some of these effects can conflict when using a shader pack. Most of the time you can disable these effects under options > mod options. For some mods you will need to change it in the config files (...\FTBInfinity\minecraft\config).
Setting the tesseract to use an alternative shader, can fix some weird looking shadows. Shaders don't like voids.
If you find more tweaks, don't hesitate to post it here below.
