Animated textures a little shakey
by Michael Taylor · in Torque 3D Beginner · 01/27/2012 (11:12 pm) · 9 replies
While working with scrolling and rotating animated textures in T3D 1.2 I noticed they appear to drop a frame once each second. Textures with contrasting details show it up better. Anyway, looks to be true for all animated textures, including water ripples and foam. A check back to T3D 1.1 Final showed no such problem.
Reproducing it is easy enough; just animate a texture with rotation and look closely, watch it jerk.
Can anyone else confirm this?

I'm using a 9800 gt right now.
Perhaps its not severe enough for anyone to notice or care much?
Or, if it might be a setting, suggest away. But I get this with a new project in the Empty Terrain level. Using the Sketch Tool cube, zoom in till the 512X512 fills half the screen. Its hard to see till you get that close.

Thanks for the reply, but it is rather hard to understand how something on my box alone could effect 1.2 that way but not 1.1.I'm using a 9800 gt right now.

I've noticed them to get 'shakey' after the animation has been playing for an hour or so...

Just thinking ... it could depend on the range from origin where the float point issue comes into effect ...

An hour? Don't think I've viewed one for that stretch yet.
@Steve
But it doesn't appear to depend on that. The waterplane looks the same any distance from the origin. And I do note the location of the origin.
I have two questions- might not be easy.
1- When installing T3D 1.2 we are advised to uninstall any other installations. What nastiness can happen if we have more than one installed?
2- Of the changes made since T3D 1.1 Final, which ones could effect the rendering of all animated textures?
I think this is beyond my abilities, but Ill have a go.
And I know this is a subtle problem I'm whining about, it's just that the idea that T3D's rendering quality has been degraded doesn't sit well with me.

Thanks for your suggestions.
But I do still wonder about multiple installs.

Found it! Now I know at least one thing Vertical Sync does. Thanks for your suggestions.
But I do still wonder about multiple installs.

The 'myth' about multiple installs is that one would interfere with another, or some such. Doesn't seem to be a problem for me... but then I think they actually meant the T3D Toolbox which I don't use.

... and the shakey animation issue I've noticed was assumed to be some sort of imprecision error that builds up over time, thus taking an hour or so to be noticeable.

You'll see less of an issue with multiple installs between 1.1 and 1.2 than different versions of 1.1. The toolbox is where most of the multiple install problems occur due to the registry keys it uses, but the editors have similar issues as some editors make use of registry keys. 1.2 uses it's own unique set of those keys though, so the only thing it should conflict with is multiple installs of 1.2 or the demo.
