Overgrowth alpha 54

Here is what is new in Overgrowth in this weekly alpha. If you are confused what a weekly alpha is, or even what Overgrowth is, please read our fancy FAQ. Basically, we are developing a massive video game from the ground up -- we are able to do this completely independently by accepting preorders for the game before it's done!

Here are a few highlights from the source repository:

• Working on batch optimization
• Cached shader uniforms
• Screenshots are fixed (press F7 to take screenshots)
• Faster decal projection on complex models
• Faster temporary decals (e.g. shadows)
• Large groups of decals batched into a single vertex buffer object
• Bug fixes

(reminder, summoning rigged ragdolls is alt-r or option-r)
