Mojang have recently dropped support for the old skin API used in Minecraft 1.6.4, this means that skins no longer show up in Tekkit and instead everyone just has a Steve skin. This client mod will fix it so everyone will have their custom skin again.
WARNING: If you used the old skin-fixer-1.0 mod, your Tekkit client will crash if you get too close to a player using a cracked account instead of an official account as the skin-fixer mod does not know how to handle them. The crash report usually starts with...
Description: Ticking screen
java.lang.NullPointerException
at net.minecraft.client.entity.AbstractClientPlayer.func_110300_d(AbstractClientPlayer.java:94)
at net.minecraft.client.entity.AbstractClientPlayer.func_110304_a(AbstractClientPlayer.java:69)
at net.minecraft.client.entity.AbstractClientPlayer.func_110302_j(AbstractClientPlayer.java:42)
Please use the new LumySkinPatch mod instead.
1. Download the mod at https://minecraft.curseforge.com/projects/lumy-skin-patch. Download and save the LumySkinPatch.jar file.
2. Open your Technic Launcher and go to the Tekkit Modpack Options:
3. Open the folder your Tekkit is installed at by clicking Open.
4. Go into the mods folder.
5. Copy the LumySkinPatch.jar file you downloaded into your mods folder.
IMPORTANT: If you used the old mod, delete the skin-fixer-1.0.jar file!
6. Now start up Tekkit and you and your friends will have their custom skins back!
