I am in the middle of a major graphics engine upgrade. This whole time I’ve been using fake HDR. Basically I divide every color by 2 when storing it in a texture, then multiply it by 2 whenever I read it from the texture. It works but you end up with lower color fidelity.

Now everything is done in full 64-bit floating point textures. Here’s an exaggerated before/after shot so you can see the difference. Notice the color banding on the left.

I was also skipping a few major steps of the usual recipe for bloom, namely downsampling and later resampling with a linear filter. The new bloom effect is much prettier. Here it is in action, along with some crazy geometry bugs I encountered while optimizing the vertex buffer code:

Lastly, I’m experimenting with a new effect for the slow-motion predictive block system:

That’s it for this week. Thanks for reading!

I'm stuck because I blew all the charges to drop the fuel rod but it got stuck on a corner and now I can't do anything.

Crap. Did it get stuck on a wall you created? You could try kicking through it if so. Otherwise... you might have to reload your last save. Sorry about that.

BTW you can hit F5 to quicksave at any time.

I just started tracking because of your shirt in the kickstarter video.... I guess the game looks pretty cool too.

Ah yes, I also forgot to mention in the video that I typed all the game code with boxing gloves on.

I love the new version, every previous issue i had is fixed, the gameplay feels more fluid, and the new more open stages allows for more movement.
The only minor issues i had was that, firstly the part to get to the hubworld feels a bit slow, and although i get that you were going for a puzzle feel i would have preferred if the boxes needed to blow up were reduced, and the slow motion being mapped to the same button as jump in sandbox felt odd, those are just minor complaints though.
All in all absolutely lovely.

@tk_aza You can scroll the mouse wheel over the motion blur setting and bring it down to zero. Confusing, I know.

@Worthless_Bums Unless it's distributed version control and you've got massive binary files. Then it's just pain and suffering.
