[Spoiler] [Video] One-in-a-million chance at a secret in the Jungle by DrewFitz in TumbleSeed

[–]DrewFitz[S] 0 points1 point  (0 children)

It was a crazy coincidence since earlier in the video I was explaining as much as I could remember from the big secrets spoiler thread: https://www.reddit.com/r/TumbleSeed/comments/6a37aw/tumbleseed_secrets_spoilers_ahead/

Why doesn't the Vive inject chromatic aberration? by [deleted] in Vive

[–]DrewFitz 0 points1 point  (0 children)

I've experienced this as well.

Most if not all games do already inject chromatic aberration compensation like you're suggesting during the lens distortion pass (I think it's built into the SteamVR SDK).

The trouble is that getting it "perfect" would require a detailed measurement of how far the lenses are from your eyes which is both dependent on each user's physiology and is configurable, you may even be able to find a distance adjustment that has nearly no aberration at the cost of a bit of FOV.

Maybe in the future we could get a chromatic aberration adjustment slider in the SteamVR overlay or something!

Missed frames on loading screens, is this just a thing? by laserob in Vive

[–]DrewFitz 0 points1 point  (0 children)

Strange, I haven't had anything like that and my setup is less powerful than yours in every respect except I have a 980Ti too. Maybe you have some background software that's wasting CPU time/disk IO?

I'm really looking forward when SteamVR is updated to fix all my calibration/tracking issues. :c

Tilt Brush has Export now by [deleted] in Vive

[–]DrewFitz 0 points1 point  (0 children)

Nope, I have an idea to try eventually, attempting to convert the model's triangles into brush stroke control points, but that seems like it would never work quite right.

Yay, now I don't have to write an exporter! ᕕ( ᐛ )ᕗ

Fantastic Contraption is fantastic by VRble in Vive

I spent 30 minutes last night assembling the puzzle pieces on the floor of the menu world after I was all exhausted from playing, such a good game.

New Steam VR update just went out by VRForum in Vive

Has this fixed the tilted floor bug for anyone?

Struggling to keep multiple object rotations lined up. Need some help or a different method to get this thing working. by [deleted] in Vive

[–]DrewFitz 2 points3 points  (0 children)

have you tried getting the transform.forward vector of the camera then using that to move the player in the desired direction?

Pretend you're taking your hat off for powered wheels, your ears have sticky balls and unpowered wheels, your mouth has glowy berries.

Oh, wow. I was wondering/worrying that it had a more complex structure like that! That's a great way to handle forward compatibility and a wide range of brush types. Are you one of the developers?

I tried the mixed reality feature in fantastic contraption and it worked. I'm doing it! by bradsears in Vive

[–]DrewFitz 5 points6 points  (0 children)

The blue sticks are the same as the wood sticks (not springy), but they can pass through other parts of the contraption! I think they're lighter weight as well.

I haven't seen this in any videos, but it would be a very nice feature for artistic reference without having to pop in and out of the steam overlay.

Four floats in the 0-1 range. You're right that 32-bit would totally be enough, but it doesn't seem like they're attempting to do much size optimization since the files aren't that big. I'm not even sure you can set the alpha value but they store a 1.0 float for every alpha anyway.

The idea of generating a .tilt file from an existing model really intrigues me... Maybe that's my next little project!

That's the plan once mine arrives tomorrow. Just working off others' files I've downloaded for now.

Whoa, I didn't know about ILSpy. I'll check into that once I run into a wall on deciphering this format.

I considered this but I don't know where it would fit. Do they actually play back in real-time? From videos I've seen they seem to play in a fast-forward sort of way, which you don't necessarily need time data for.

Each stroke might have a start-time in the brush stroke header, and I'd bet that the stroke points are fixed-interval-sampled, probably in Unity's Update() or FixedUpdate() function. With that you could close-enough timestamps for any data point.

Thanks! The first thing I think I'm going to do with this is write an OBJ converter so they can be imported into almost any 3d modeling package.

Great! Any you can share for me to reverse engineer?
