Chameleon is a shared code library required by jaquadro’s mods, available for Forge on Minecraft 1.8–1.12.2. It provides a more comprehensive RenderBlocks replacement suitable for TESR rendering, but does not include hooks to restore the 1.7 rendering pipeline.
Rent your own Minecraft server and install Chameleon with one click from the panel to provide the library your jaquadro mods require.
