About RenderLib

RenderLib is a client-side only mod that makes necessary changes to entity and tile entity rendering for some of my other mods (Other ports of mods which were also made by Meldexun). This mod on its own does not provide any meaningful improvements regarding performance and you probably only want to install it when using a mod that has this mod as a dependency.

Requirements

This port already pre-bundles org.spongepowered and its other dependencies (it.unimi.dsi:fastutil:7.1.0).

It requires ConfigurationsBackport v1.1 present here: https://modrinth.com/mod/configurationsbackport

Frequently Asked Questions

Does RenderLib 1.8.9 port need to be installed on the Minecraft server?

No. Modrinth marks RenderLib 1.8.9 port as unsupported on the server side. Install it only in your local Minecraft mods folder. Your server can remain unchanged unless the mod page lists an additional dependency.

Which version and loader does RenderLib 1.8.9 port require?

Use a file for forge and your exact Minecraft version. Supported versions include 1.8.9. Files for different loaders are not interchangeable.

RenderLib 1.8.9 port is not working – what should I check?

First check the Minecraft version, loader version and required dependencies. Put the .jar file in your local .minecraft/mods folder and remove older duplicates. Because this mod is client-side, adding server RAM will not fix it.
