I am trying to use the heuristix gun mod, it works (Atleast it doesn't crash at startup) but the gun sights show up as all white whenever I try to zoom, please help.

There are /so/ many things wrong with this post. First, can you give us /any/ information? Crash reports, console warnings, screenshots, anything? Have you done any research? What versions are you using? Second, this should probably go into the Support/Bug Reports section. Third, this should /probably/ go into the thread for the mod that you're using.

*stands back and waits for LexManos to flame you*

Give us some kind of code or errors at least!

 

Also you are very unlikely to get help if you are not using forge.

Out from your post, this is the best emoticon expressing how I feel about helping you:

Here are the logs

Couldn't you have just read the log? "Optifine is installed or is missing files." Also, fuck MCPatcher.

Can you read the logs it has nothing to do with optifine:

Caused by: java.lang.LinkageError: loader (instance of  net/minecraft/GameUpdater$2): attempted  duplicate class definition for name: "Item762x51mm0"

Your launcher is fucked up, whatever launcher you're using

 

Aside from that the mod is trying to define the same class twice, so thats your issue, go speak with the mod author, not us.
